History GoodBadBugs / RolePlayingGame

** The 'Talk and Fight' bug was another useful, though very situational, bug: Any non-hostile character whom you are currently talking to or have a character lined up to talk to will have their AI disabled and will not go hostile while the character ordered to talk to them is underway. This allows you order one character to engage an NPC in dialogue, while ordering the other members of your party to, well, engage the NPC in less courteous modes of communication (like, say, a sword to the shin). The NPC, still waiting to be talked to, will sit there and take it as long as the would-be talker is still en-route and for several seconds afterwards. While it will not work on any enemy that requires a scripted event to die (such as the BigBad and the most difficult BonusBoss), it does wonders against the game's literal dragons who are not hostile towards you by default. AI mods were eventually released to kill this problem.

** The Tempest rogue specialization's Flask of Fire ability negates the stamina cost of abilities. This also applied to [[LimitBreak Focus abilities]], whether the Tempest's own [[SpamAttack Thousand Cuts]] or the [[PlayerCharacter Inquisitor]]'s Mark of the Rift. Proper usage allowed Tempests to utterly eviscerate any encounter, even [[BonusBoss High Dragons]]. This has since been patched.

* ''VideoGame/BookOfMagesTheDarkTimes'' has a glitch where a single trip to the Mana Cave can grant you more skill points than you're possibly able to spend. In the early game, trips to the Mana Cave are the only way to level up at all; the upshot of this is that you can be almost as strong as the game's BonusBoss before your ''first battle'', completely removing any difficulty whatsoever for the entire rest of the game and allowing you to [[CurbStompBattle curb-stomp]] even the early HopelessBossFight.

*** One of the BonusBoss enemies, the Egg Dragon, had the highest amount of HP possible. However, the programmers failed to cap his HP, and beating him is a simple matter of healing him with the weakest potion to cause his HP to roll over to double digits and then attacking.
*** The other BonusBoss, the Master Slime, is more of a case of PuzzleBoss disguised as a {{Good Bad Bug|s}}: you need to either kill him through pure damage or kill your own party to win the battle properly. However, neither option is easy, since you only have 3 turns to kill him and the first thing he does is heal your party to full, and if the 3 rounds pass without him dying, he attacks himself and kills himself instantly. Either way you can't really lose the battle ''per se'', but not doing the above causes him to say that you've failed and he won't give you a key to a room with a bunch of {{Bragging Rights Reward}}s inside, forcing you to redo the entire BonusDungeon from the beginning for another attempt since it has no save points.

*** One of the most famous glitched Chalice Dungeon glyphs is "''cummmfpk''" (sometimes jokingly called the [[FanNickname "Cum Dungeon" or "Cum Chalice" by fans]]). The very beginning of this chalice spawns an inactive Hunter NPC in front of a pendulum trap within the game's rendering distance but outside of aggro range, where the trap will eventually kill the NPC on its own without the player having to do anything. This instantly gives the player roughly 100k Blood Echoes on the spot (depending on equipped Runes), and the NPC Hunter will respawn if you leave the chalice and come back, turning this into the best Echo farming spot in the entire game by a huge margin and allowing you to level characters in minutes.

* ''VideoGame/{{Minecraft}}'' Hypixel's version of [=SkyBlock=] allows you to fly with DoubleJump and the grappling hook item, [[https://youtu.be/vLLJAiII6p4?t=394 as discovered by]] ''LetsPlay/{{Technoblade}}''.

[[folder:The Elder Scrolls]]
''Franchise/TheElderScrolls'' series: %%Please leave for cross-wicking purposes.

* ''VideoGame/TheElderScrollsIVOblivion'':
** A bug lets you duplicate any object hundreds of times. Cue [[https://www.youtube.com/watch?v=hmszTpK54Mk Youtube videos]] of players flooding cities knee-deep in watermelons and human hearts.
** Make two copies of an enchanted wearable item. Equip one copy. Duplicate the unworn one. Both fall off, but the effect remains. Change clothing on another body part to make it permanent. Stack enchants to your heart's content. Alternatively, just be wearing enchanted items during one of the few moments where the game forcibly removes your gear.
** Also: paintbrushes aren't affected by gravity, allowing you to construct stairways, sniper's nests, and so forth out of dropped art supplies.
** Enchanting enough armor pieces and accessories with chameleon effects [[GameBreaker turns the wearer permanently invisible]]. Hilariously, people could see your character fine in town... even if the player couldn't. These same people would not notice you if they then went outside the town gates and you stabbed them with a broadsword.
** There's also the hilarious physics of jumping off items you're holding below you in mid-air, which makes for some great speedrunning tactics.
** ''Oblivion'' has magic spells that spawn enchanted ("bound") armor and weapons. They have very strong attributes and zero weight, but the game balances this by making them only last for a while -- then the spell wears off and they disappear. But if you let the item get damaged, repair it and then drop it, it won't vanish when the spell wears off. You could then pick it back up and have it [[GameBreaker permanently in your inventory]].
** If you attack a guard in the Arcane University, occasionally every NPC in the University will break out into a full-on brawl.
** And then there is the famous door physics glitch. If you drag a body into a doorway and then shut the door in just the right way, the door will close and the body will get stuck in it. The collision detection goes crazy and results in a [[https://www.youtube.com/watch?v=3EyFURUovb4 flailing corpse stuck in a door or wall.]]
** If you are suspended from the Mages' Guild, you are required to gather alchemic ingredients for Raminus Polus to get back in[[note]] 20 Dragon's Tongues and 20 Redwort Flowers for theft, 20 Vampire Dusts and 20 Daedra Hearts for murder[[/note]]. If it's your first offense, a glitch allows you to get back in if you collect 20 pieces of only one of the required items.
* ''VideoGame/TheElderScrollsVSkyrim'':
** ''Skyrim'' wasn't out for even a week before people found out that, due to how the new game engine handles eyesight, you could put buckets on people's heads and they won't see you stealing. Realism at its finest. If they could figure out how to take off the buckets, it would be nice though. According to Todd Howard, they learned about the bug the day after release. The lead programmer wanted to fix it but Howard insisted it [[ThrowItIn be left in]].
** For a while, it wasn't uncommon to find dragons [[https://www.youtube.com/watch?v=GZXqdj0G3Ag flying around backwards.]] This was fixed in a patch.
** This being an Elder Scrolls game, horses being capable of climbing up ludicrously steep slopes is par for the course; but it is possible to get them to climb slopes that the developers didn't intend for them to be able to climb by holding forward onto a steep slope and waggling the control left and right; the horse will usually find some invisible purchase and glitch their way up the mountain. It is possible to reach The Throat of the World before learning the Clear Skies shout in this way.
** Take the ''Necromage'' restoration perk (which improves spells you cast on undead) and now your self buffs are stronger if you are a vampire. This makes some sense, but it also affects passive effects that are not actually spells but are implemented in a similar way, such as some perks, potions and all armor enchantments.
** The ''Aspect of Terror'' perk improves the level cap of fear spells by 10 points. It also buffs the damage of your fire spells by 10 points because there's a perk that causes them to make enemies flee in panic so they're considered fear spells. This is particularly useful for the Ignite spell, which deals its listed damage per second for 15 seconds, so you get 120 extra damage out of this.
** The Ritual Stone offers a power that reanimates all corpses around you as zombies, but only once a day. You can store standing stone effects into a certain item (Aetherial Crown) and unequip and reequip it to reset the cooldown for unlimited zombies that roll over anything in your path.
** The Marked for Death shout is supposed to reduce a target's armor temporarily. Due to an incorrect flag, it inflicts its armor drain ''permanently'' and applies it sixty times over the course of a minute. This results in an irreversible 4500 armor penalty, increasing damage taken more than six times, and it stacks with itself if you shout more than once. Killing a dragon in one hit with an iron dagger is absolutely possible.
** Refunding your perk points does not actually remove some perks. You get the point back but keep the effect.
** Due to a bug in the physics engine, getting killed by a giant's club will [[https://www.youtube.com/watch?v=Oso_mmhvm-Y launch you]] [[https://www.youtube.com/watch?v=GwzCVjn7f8k or your companion a few miles into the sky]]. This bug is inherent to the physics of the Gamebryo Engine ([[BlatantLies which Skyrim's engine is not at all based on]]) and has showed up (much less frequently) in previous games using it. In particular, bodies are light and the shockwave has an extraordinarily high push value.
** While the giant's club is specifically an item, it's also flagged so your character cannot pick it up and wield it. Your followers, however, do not have this restriction. Thus, it's sometimes possible to order your follower to pick up a club, meaning you get to see Lydia beating people with a massive bone bigger than she is.
** Due to another physics bug, riding your horse onto the head of the dragon from above has... [[https://www.youtube.com/watch?v=u9QbWhL6cD8 interesting effects.]]
** Casting a fireball on a dead dragon skeleton will toss it around like a toy. If you do it on top of a mountain, it will fly further than the console's draw distance.
** For some reason the Jagged Crown never counts as headgear and sometimes wants to count as a shirt.
** Potions of Fortify Restoration increase the power of restoration spells and effects. This includes potions and (clothing/armor) enchantments. You can enchant equipment with Fortify Alchemy, which will also be effected by the potions, allowing you to make more powerful Fortify Restoration potions, boosting your Fortify Alchemy Enchantments (though you have to unequip them and put them back on after each potion for it to take effect); repeat ad infinitum. This eventually leading to potions and equipment that bestow billions of hit points, let you Shout without cooldown, or [[VideoGame/ColossalCave kill a dragon with your bare hands]].
** Completing the Daedra quest "Discerning the Transmundane" earns you the Daedric Artifact "Oghma Infinium", a tome that boosts all skills in one of three classes (Warrior, Mage or Thief) by five points. However, the downside to using said tome is it will disappear after first use. Before patch 1.9, this could be avoided by exploiting a glitch involving [[ItMakesSenseInContext a bookshelf and careful hand coordination]], allowing you to [[GameBreaker boost all skills over time]] and reach level 81 [[DiscOneNuke before even making it through 1/8 of the main quest]]. The patch which fixed this not only prevents you from doing the trick, but actually ''punishes you'' for attempting to try it--the book will disappear from the game completely if you attempt to put it on a bookshelf, preventing you from gaining the bonus you're ''supposed'' to get.
** It's not particularly useful that sometimes mannequins animate and might walk and follow you around. But the scare it gives you sure is fun.
** One of the biggest complaints about the 1.9 patch is that it removes a glitch that would occasionally cause the courier to show up [[NakedFirstImpression wearing only a hat]].
** If you steal from someone, even if you aren't caught, eventually you will run into three goons labeled "hired thugs" sent to kill you. Kill them, and at least one will have a letter signed by the person you stole from, typically a home owner. However, a bug leads to just about anyone and any''thing'' capable of hiring thugs to kill you. This includes children, guards, animals, monsters, ghosts, and even people you haven't even met yet. Some will even send hired thugs after you for [[DisproportionateRetribution knocking things over]] and may send thugs after you even after they are dead. On rare occasions you may also see a giant naked NPC called "[=TestJeremyBig=]" or a small one called "[=TestJeremySmall=]" during these encounters, who have miniscule stats and run away as soon as you go hostile; as their names imply they were included in the engine for testing purposes and not actually meant to be seen in normal gameplay.
** The ''Survival Mode'' DLC reduces your attack speed when you are hungry. Unless you have any other effect that changes attack speed, in which case it greatly increases it instead.
** You can use wooden plates to clip through walls and doors by holding the plate up against a surface and sprinting into it, letting you access areas you're not supposed to and allowing for some truly ridiculous SequenceBreaking (such as skipping the entirety of Blackreach by clipping into the Tower of Mzark, or getting into the Thalmor Embassy prematurely and ''skipping half the main questline''). This works especially well with the Whirlwind Sprint shout.
** One specific type of bucket (the one with a handle) has different collision properties than the others, [[https://youtu.be/3SYe1plGuDk allowing you to fly by standing on top and grabbing it]].

** If you steal from someone, even if you aren't caught, eventually you will run into three goons labeled "hired thugs" sent to kill you.

* ''VideoGame/TheElderScrollsArena'':
** It's possible to beat the game by collecting scrolls in a single dungeon roughly 18 times, due to the plot-important item in it respawning. Also you can stack Amulets with the Necromancer's Amulet to create a huge defense bonus, exploit the repair option at equipment stores to get artifacts repaired for 13 gold in one day (it's supposed to be 10,000 gold for 10 days), cause the amount of items in treasure piles to go up simply by climbing and going down dungeon stairs, and duplicate weapons and armor. The best one, though, is that, while you were meant to only get one artifact (at least until you use that artifact's special abilities enough times it disappears from your inventory), you can use the artifact's magic abilities at least once, leave it to get it repaired, and {{Non Player Character}}s will start nudging you toward side quests to acquire more artifacts again.
* ''VideoGame/TheElderScrollsIIIMorrowind'':
** One of the easiest money earning methods takes advantage of a rounding error, and doesn't even require decent stats: the game works out the total price of goods differently depending on whether you click on a whole stack of items at once or add them individually. Simply pick up a large stack of cheap items. Go to a merchant and add them to your "sell" stack one by one and the game will raise the price by the minimum value rounded up to a whole coin on each click. Sell four hundred arrows, then [[MoneyForNothing buy the whole stack back for just one]]...
** Because potion effects stack, if you drink two sujammas, your Intelligence attribute will be drained entirely, but once the effect wears off, your magicka reserve will be restored entirely.
** The Soultrap spell has a glitch that, if combined with another spell effect, will make the latter permanent. This can allow you to create entire armies of summoned creatures that never disappear, and can allow you to max out your stats to god-like levels. All without worrying about the effects running out.
** Draining and/or damaging a skill's level before getting it trained will have the trainer treat that stat as is, allowing you to level a skill to 100 with any trainer and cheaply too. Of course this also means if you fortify a skill, it'll cost more to level for no reason.
** By 'juggling' weapons that grant stat bonuses, it's possible to have the effect stack with itself and render you nigh-godlike. This allows you to complete the game in a [[http://speeddemosarchive.com/Morrowind.html matter of minutes]].
** You can fire projectivles [[TacticalDoorUse through closed (interior) doors]] to overcome staggering odds.
** The game forgets to remove the "Unique Dwemer Artifact" from Vivec's inventory after you accept the restored Wraithguard from him, meaning that, if you kill him after taking the powered-up Wraithguard from him, you can have Yagrum Bagarn jury-rig the aforementioned artifact and have '''2''' Wraithguards, one for each hand[[note]]for whatever reason, the Jury-rigged Wraithguard is left-handed, whereas the regular one is right-handed[[/note]]. You'll still have to deal with the massive health loss from the jury-rigged Wraithguard though.

** If you steal from someone, even if you aren't caught, eventually you will run into three goons labeled "hired thugs" sent to kill you. Kill them, and at least one will have a letter signed by the person you stole from, typically a home owner.

Some will even send hired thugs after you for [[DisproportionateRetribution knocking things over]] and may send thugs after you even after they are dead.

** One of the most popular glitches is the Cinnabar Coast glitch, where there's no data for what Pokémon you're supposed to encounter there[[note]]specifically, Pokémon you can encounter in the tall grass; Cinnabar has no tall grass so this wouldn't be a problem, except the water tiles on the coast count as tall grass because of a quirk with how determining whether tiles should be a certain type of encounter tile[[/note]], so it uses the same data as the last place you were where you could fight and catch Pokémon. This glitch was fixed in the Spanish versions of ''Pokémon Red and Blue'', as it was apparently discovered before it was released in that language.

* In ''VideoGame/UnleashTheLight'', Amethyst's Show-Off skill makes one of her moves free whenever the Teamwork Bar fills up, once per battle. However, there's a glitch where this move is permanently made free, so if it's one of her strongest attacks, you're free to spam it on your enemies.

* Not as epic as some of the above, but rather satisfying: in the old ActionRPG ''VideoGame/AncientEvil'', undead enemies, when slain, would get up again after about ten seconds. The tougher undead could permanently drain your EXP if they hit with an attack, so the best response was to run like hell. However, if the game was saved and loaded, any bodies on the ground would be converted into bones, and this included the bodies of undead. Bring one down once, save and load, and it's gone forever, [[DemonicSpiders probably to your relief]].
* ''VideoGame/StarControlII'' had the infamous "planet-lander" bug: In the original version, attempting to sell a planet-lander when you had none to sell would cause an underflow bug, leaving you with around two million or so planet-landers, that you could then sell for cash.
* ''VideoGame/TheFinalFantasyLegend'':
** Thanks to some backwards math, the Saw item is an instant kill against strong monsters, like the final boss, instead of weak monsters.
** Martial arts weapons, which get stronger the fewer charges they have left, stack. List a near-empty Headbutt above a fully stocked one and the fully stocked one will do as much damage for each use.
** ''VideoGame/FinalFantasyLegendII'' fixed those bugs, but added a few more, most of it Robot-related (new class). Robots get stat bonuses for their equipment as long as they have it equipped. Wearing martial arts weapons gives Agility, but they don't deal the progressively higher damage per use. But once a Robot uses up said weapon, it disappears and they still keep the stat bonus.
* ''VideoGame/SagaFrontier'':
** Takonomics, named in honor of the man who discovered it: in Koorong, the price of gold goes down as you sell ingots and back up as you buy, but this calculation is (erroneously) made ''before'' any actual physical inventory changes hand. You can therefore manipulate the gold market in the shop menu such that when you actually sell your gold, you get more money back. Then you travel to Nelson, where gold ingots are always sold at a fixed price, and repeat until you have all the money you'll ever need.
** In addition, the well-loved Overdrive-Stasis trick, even though it ''seems'' like it may have been on purpose due to the moves descriptions ("Temporarily gain infinite speed" and "freeze time in battle"), is actually a glitch- see Zaraktheus' last post [[http://www.gamefaqs.com/boards/198537-saga-frontier/51404644?page=36 here]] for an in-depth explanation. It can be taken even further with the use of the Shadow Servant spell, which creates a shadow doppelganger that copies any spell or attack you use, effectively doubling the damage dealt in those eight turns.
** This glitch has a similar effect if a snake oil item is used by the caster on himself in lieu of Stasis, without the side effect of being in stasis after Overdrive ends. This means that Time Lord does not have to complete the Rune Quest in the four quests which he is recruitable, and could be the most useful character in the game.
** The Junk Shop glitch, which allows you to get endless free stuff from the Junk Shop in Scrap: just attempt to sell a [=HyperionBazooka=] that you don't have and you get seven free items. Perfect for either kitting yourself out with DiscOneNuke[=s=] or building up enough money to engage in Takonomics.
* ''VideoGame/WildArms1'' has an item inventory glitch where if you switched places of items during battle after having other characters use them, it reduced the number of the wrong item. How this works is that an empty inventory space is still marked as "containing" the item that once occupied it (at the beginning of the game all the empty spaces are marked as duplicators or something), so if you used an item marked as "0", it'd roll "back" to 255. If you decided to duplicate [[RareCandy Apples]], then your characters could become little walking gods almost literally a couple of hours into the game.
* ''VideoGame/WildARMsXF'' has a similar item duplication bug to the original. One could gain scores of items by having one of the desired item left, then having a Harpy steal it in battle and then using it at the same time.
* ''Amulets & Armor'' has a great bug dealing with the "death cam", the red-tinted view of the world you see when you die. Your character is actually still alive, the game just disables the keyboard. However, ''A&A'' has mouse navigation too, which it doesn't disable, letting you explore (and even beat) levels while dead.
* ''VideoGame/{{Lufia}}'':
** ''VideoGame/LufiaTheRuinsOfLore''
*** One of the skills that can be learned well into the game is Sacrifice, a free move that deals 999 damage to a non-boss enemy but kills the user... unless you target ''yourself'', in which case Sacrifice is an awesome skill that fully heals yourself without cost.
*** There are two easy ways to get huge sums of cash quickly. The first uses Blue Tea, an item found only in Ordens (limited time offer!) that can be bought in bulk for 100 each and then immediately sold back for 150. Later, when the blacksmith in the beginning area becomes available, a simple bug can be used to get a limitless amount of whatever item he just made (except the last), creating an even quicker supply of cash. Stock up on cash when you get the chance, and you can buy the very expensive and (at that point in the game) {{game|Breaker}}-breaking Zircon equipment later.
*** One item you can have made by [[ItemCrafting blacksmiths]] is Nectar, which fully restores a character's HP and AP. Such an item would be TooAwesomeToUse, given the scarcity of the ingredients...except creating the Nectar doesn't consume the ingredients, and thus an infinite amount can be created.
** ''VideoGame/LufiaIIRiseOfTheSinistrals'':
*** One of the BonusBoss enemies, the Egg Dragon, had the highest amount of HP possible. However, the programmers failed to cap his HP, and beating him is a simple matter of healing him with the weakest potion to cause his HP to roll over to double digits and then attacking.
*** The other BonusBoss, the Master Slime, is more of a case of PuzzleBoss disguised as a {{Good Bad Bug|s}}: you need to either kill him through pure damage or kill your own party to win the battle properly. However, neither option is easy, since you only have 3 turns to kill him and the first thing he does is heal your party to full, and if the 3 rounds pass without him dying, he attacks himself and kills himself instantly. Either way you can't really lose the battle ''per se'', but not doing the above causes him to say that you've failed and he won't give you a key to a room with a bunch of {{Bragging Rights Reward}}s inside, forcing you to redo the entire BonusDungeon from the beginning for another attempt since it has no save points.
* ''VideoGame/{{Diablo}}''

* ''VideoGame/{{Mother}}'':
** ''VideoGame/EarthBound1994'':
*** There is a bug concerning the use of the condiment items with any food item in the bottom two slots of a character's item-list during battle which can be exploited to use the random-stat-increasing "Rock Candy" item infinitely. Additionally, due to one condiment being able to double the increase effect of Rock Candy, this allows even HP-lacking characters like Paula and Jeff to easily exceed 1000 HP with about 30 minutes of abuse and a subsequent level-up, though ''[=EarthBound=]'''s HP display is limited to three digits. It must be used cautiously, however - [[OverflowError boost a character's stat past 255 and it'll end up at 0!]]
*** ''MOTHER 1+2'', the Japan-only CompilationRerelease of the first two games for the [[UsefulNotes/GameBoyAdvance GBA]], has a very odd glitch during the FinalBoss battle against Giygas. If the player uses a Viper (an item that [[AlwaysAccurateAttack always]] inflicts poison) on Giygas during the second phase, a programming oversight will allow Giygas to be poisoned, unlike in the original SNES version where he is immune to it. Once this occurs, if the DamageOverTime from the Viper causes his HP to reach 0, instead of [[ScriptedBattle automatically moving on to the final phase]], Giygas will instead "die" like a regular enemy (awarding 0 EXP), and the ending will proceed to play as if the battle was won normally.
** The strange way ''VideoGame/MOTHER3'' saves and loads data can cause an accidental NewGamePlus in which you begin with the best equipment and all PSI.

* ''VideoGame/PhantasyStarUniverse''[='s=] first summer event introduced swimsuits. These were treated as a single item that takes up all three clothing slots, meaning you couldn't mix-and-match as you can with the rest of the game's clothes. By going into the Xbox 360's Guide and choosing "Join Session in Progress" with another friend playing the game, all your clothes would show up as unequipped, but you would still be visibly wearing them, allowing you to equip another "layer" of clothing over the first. By having a swimsuit as your first layer, you could then put on some normal pants, while keeping the swimsuit top (bikini top for girls, shirtless for guys). Though the bug was fixed, it was popular enough the swimsuit items were later split into separate pieces for the tops, bottoms, and sandals.
* In the Playstation version of ''VideoGame/AzureDreams'', careful use of a certain transforming {{Mon|s}} can allow the player to duplicate items as long as their monster has enough MP to morph (intentional). Less careful use of the same monster can allow the player to [[GameBreakingBug freeze the game]] (unintentional).
* ''VideoGame/AdventureQuest'':
** The Power Katana weapon caused some odd bugs. In ''[=AdventureQuest=]'', the armor the player character wears determines the number of hits done with each attack during a turn, but it also determines what percent of the weapon's damage is done per hit. The Power Katana, probably due to it being the only item that scaled with your level at that time, did not play nice with the latter. Instead of damage being divided over each hit, each hit did full damage, which was insanely broken if the player paired it with an armor that performed several weak hits, allowing you to do up to six or seven times standard damage. The bug was, however, eventually patched.
** Weekly releases tend to have a few hiccups before a patch later in the day, such as the 2015 Giftbox armor bugged to deal 100% damage for two hits rather than 50% damage each. Banshee Form armor had a bug that lied unnoticed for ''months''. Banshee Form, on paper, was a strictly inferior Darkness-element armor compared to others, but in implementation, it was bugged to deal double damage compared to other armors of the level. People who actually used Banshee Form would have a much easier time clearing the game before it was patched.
* The first release of the necromancer armor in ''VideoGame/DragonFable'' had a "Final Strike" ability dealing two or three times what was intended.
* ''VideoGame/SuikodenII'':
** There was a bug during the first portions of the game where you could push a seemingly sturdy locked gate and complete a side quest you weren't supposed to many dozens of hours into the game later. If you can survive at least until you get to a town to recruit two party members to complete the side quest, you can level grind for a while. By the time you're done, you should have at least five characters who can kick ass and take names until ThatOneBoss.
** There were some [=NPCs=] in the game who spoke gibberish when you talked to them. The translators actually forgot to translate some of the text strings from Japanese to English, and the English version of the game lacked a Japanese font, thus producing something completely illegible in either language.
** Luca Blight is normally ThatOneBoss, but there is a glitch that makes him incredibly easy, so long as you don't mind the fight lasting a lot longer and only the main character getting any EXP from it. Right before you form your three teams for taking him on, leave the room and form a team and place the main character in the back row. Then go to form your teams. He will be by himself again. Don't put anyone else in that group. When you reach the third battle against Luca, the main character will in the back row. All of his main attacks will completely miss you, and the only thing you need to worry about as you [[CherryTapping cherry tap]] your way to victory is an occasional counterattack. [[https://www.youtube.com/watch?v=cFQuIr4Mjig Even then, however, it does a negligible amount of damage that can easily be negated with a Medicine or two.]]
** The game features fairly standard {{Trauma Inn}}s throughout the game. However, while the game was programmed to check if you had enough money before staying, it wasn't programmed to actually deduct the money until after the party had slept. If you cancel out of the [=Don't Save/Save=] option, you will be fully healed without paying anything.
* There is a trick in the Game Boy Advance version of ''VideoGame/KingdomHeartsChainOfMemories'' that allowed Riku in dark mode to keep the effects of support cards that affected a finite number of attacks like Overdrive and Attack bracer indefinitely. All you had to do was double-jump and attack. You deliver a multi-hit attack with the effects of the support cards and the counter does not go down. Useful for beating Ansem!
* ''VideoGame/QuestForGlory'':
** The VGA remake of ''VideoGame/QuestForGloryI'' has a bug in which you could sell your mushrooms to the healer infinitely, even when she says she has enough of them, thus allowing one to rack up as much as 100 gold early in the game.
** ''VideoGame/QuestForGloryIV'':
*** Early versions have an interesting one. Finish the game and restart with another class. You'll find yourself in the Dark One's cave with all rituals nearly completed, since all flags have not been resetted properly. [[DungeonBypass It's just a matter of climbing your way to the Big Bad, complete the last ritual and finish the game again.]]
** Whenever you fight, your stamina will slowly regenerate itself. However, because of the speed cycle bug, your stamina will instantly refill! This makes training your skills very easy. Train climbing until exhausting, then find a monster, restore your stamina, kill the monster. Rinse and repeat 'til your skill is maxed out. Rinse and repeat with the next skill.
** ''VideoGame/QuestForGloryV'':
*** There is an item duplication bug, where you stand in an area and remove a single item in your inventory. The character, for some reason, throws the item up in the air. While it's still in the air, it's also still in your inventory--which means you can remove it again and watch the second inventory item sail through the air. If you're really quick, you can use this to duplicate a number of them before the first hits the ground. You can then sell the duplicates to the shopkeeper. Naturally this is best done with the expensive items in the game, like magic chainmail. It only works with a single item, though; if you have multiples of the same item, you'll just remove those multiples from your inventory. I believe it also only works with items that can be bought and sold to the centaur shopkeeper.
*** A bug occurs after the player completes the game once. After starting a new game, the PC can walk out of Silmaria and find the hot-air balloon already made and waiting for him.
* The Apple II version of ''VideoGame/{{Wizardry}}'' had a bug where successfully identifying the "item" in slot #9 (you could only carry 8 items) would give your character 100 million experience points. This became an AscendedGlitch when it was intentionally included in the IBM PC version.
* In ''VideoGame/NostalgiaRedEntertainment'', the Golden Chalice item revives a party member with full HP. Due to a glitch, using this item will also give the party member up to eight extra turns. With judicious buffing and multi-attack skills, it's possible to do OverNineThousand points of damage.
* ''VideoGame/NeverwinterNights'':
** You can be hit by a ''practice dummy'' during the tutorial. In order to use it as a target, they had to program it in as a creature; while it doesn't get normal attacks, it does get attacks of opportunity when you make a dim move near it.
** Some weird combination of Rogue/Sorcerer, Charisma enhancing magic items, and a scroll of Tenser's Transformation can result in the player suddenly being able to cast each spell level they have 1024 times. You can go from having two Stoneskin spells to having more than a thousand, which in turn means you can handle physical damage equivalent to being repeatedly trodden on by Godzilla, with only a brief interval when you hide from it and cast Stoneskin again. As it happens, this also applies to elemental damage resistance spells. This bug was discovered when taking on a White Dragon. Cue large amounts of not dying.

* ''Franchise/{{Disgaea}}'':
** The PSP version of ''VideoGame/DisgaeaHourOfDarkness'' has several bugged items that were not present in the [=PS2=] original. A pair of glasses known as Foresight, which is readily available in the shop once certain conditions are met, contains specialists that are far more powerful than those available on any other item in the game, including maxed-out Statisticians and Armsmasters (which increase the rate of XP gain and weapon skill gain respectively) which come pre-subdued and can be moved to any other item immediately. In a game that literally requires hundreds of hours of grinding to get to some of the highest-level content, this can speed things up dramatically. On the minus side, equipping one of these items will render a character unable to move, although equipping a second one will nullify this effect. Futhermore, if you enter the Item World for a glitched item, every enemy will be a Laharl clone. A level 1500+ Laharl clone.
** Since at least ''VideoGame/Disgaea3AbsenceOfJustice'' (both on the UsefulNotes/{{PS3}} and UsefulNotes/PSVita versions) and possibly earlier, any enemy that just so happens to be Level 99 accidentally has its experience calculated improperly and winds up having the Experience Points of an enemy that's Level 297 or so, which can be rapidly exploited (in ''Disgaea 3'''s case, by combining three Level 33 zombies during a certain level in Chapter 5) by getting your characters dozens of levels within an hour or two, allowing you to breeze through the main quest -- assuming, of course, you manage to be able to kill them.\\
\\
It's potentially verging on ''AscendedGlitch'' now since this bug, while not explicitly acknowledged by Nippon Ichi, is still alive and well in ''[[VideoGame/Disgaea4APromiseUnforgotten Disgaea 4]]'' (and its remake on the Vita) and ''VideoGame/DisgaeaDimension2''. In fact, both games have levels that seem to be designed around exploiting this glitch, with enemy levels easily boosted to level 99 through the Cheat Shop and, in ''Disgaea 4's'' case, the map itself being just one destroyed geoblock away from granting an additional 150% experience.
** ''VideoGame/Disgaea4APromiseUnforgotten'' has a cloning glitch. It's already helpful on its own to duplicate rare or unique pieces of equipment, but the fact that specialists are clones alongside the item pushes it into GameBreaker territory. Even common specialists can be cloned, maxed out, and stacked together quickly with this glitch, leading to absurdly powerful weapons and huge stat increases, as well as huge Exp and Mana bonuses, provided you have the right specialists. In fact, it is so game-breaking that Nippon Ichi fixed it with a patch (Said patch can be deleted if you have already installed it, but you'll have to delete all your saves along with it).
* ''VideoGame/DivineDivinity'':
** The "Polymorph" spell that turns an enemy into a harmless critter. The duration for the spell ''should'' be only a few seconds... but it's actually permanent. And it works on bosses. ''And'' you get full exp and item drops.
** The game also has a movable bed in one house; most beds are unmovable, but this one was different because it was blocking a hatch. However unmovable objects have no established weight, and the game has no encumbrance limit. You could put the bed into your inventory and have a free health/magic restore whenever you wanted. This also works with combining two hay balls inside your inventory.
** You could multiply identical items like gems by offering them to a trader, then write a negative number into the "Place on table" option and enjoy 255 items sold plus one more in your inventory. What's more, traders like you much more for your generosity as well.
* ''VideoGame/{{Wasteland}}'' has the super loot bags, filled with the rarest items in the game, the Red Ryder easter egg gun, and a lot of non-items with names like NAME and RUSSIAN. The NAME item is particularly useful: Depending on how you equip it, it can function as impenetrable armor or a gun with the maximum damage, and can be sold for $32,000.
* ''VideoGame/DarkChronicle'': has two major useful glitches:
** The first is the "Lure Glitch". You need to have recruited Olivie, two lures (which are bought from the aforementioned character), and the Lure Rod (which can be bought or invented). Equip Max with the Lure Rod and attach one of the lures to it, then in the status screen, flick the cursor over to either Monica or the Ridepod. Highlight the lure you didn't equip and by repeatedly mashing the X button, you can duplicate the lure attached to the rod up to 999. When you unequip the lures, they can be sold for an exorbitant amount of Gilda, and this can be repeated so long as you have two lures in your inventory.
** The other involves Name-Changing Tickets you can buy from Mayor Need with medals. By using them, you can turn a weapon into any other weapon in that same class, as long as the name is exact. You can for example turn a weak store-bought Battle Wrench into the InfinityPlusOneSword LEGEND just by renaming it that.
* A glitch in ''VideoGame/SecretOfMana'' on the SNES enabled a player willing to risk game save corruption the chance to fight the very first boss all over again -- provided they made use of the cartridge's built-in soft reset feature -- and obtain a ninth sword orb. As other ninth-level weapon orbs were dropped by enemies in the final dungeon, this was the only way to obtain the last forged incarnation of the game's legendary blade. (The intended way is to cast a temporary enchantment on the sword.)
* A programming oversight in ''VideoGame/BatenKaitos Origins'' can make a large portion of the game much easier. Mountain Apples raise your entire party's HP by 5% each. The effect will stack if you take multiple. Given how you have about twenty free inventory slots and never need more than two or three slots open at any time, you can carry around fifteen or so apples and get tremendous boosts to your HP. Considering ''Origins'' is very NintendoHard, this is a ''godsend''.
* Not exactly a bug per se, but the Dreamcast version of ''VideoGame/SkiesOfArcadia'' would start working harder (the system would make audible noise) just before a random encounter. This mildly offsets the annoyance of the random encounters, giving you a second to prepare for the upcoming battle. What ''is'' a bug is that you can use this to skip roughly every other fight: if you pause as you hear the Dreamcast load, change Vyse's weapon, and unpause, the battle will cancel. Since the fight's already loaded, the next random encounter will load instantly with that battle data, but used well this can effectively cut your random battles in half.

* ''[[VideoGame/DotHackGU .hack//G.U.]]'':
** On the 2nd game, there is a part where you get to walk inside the Moon Tree's @home. In the last corridor just before the [[spoiler: white hall leading to the fight against Innis]], there is a small section of the wall that you can simply walk through. [[http://img694.imageshack.us/img694/5415/moontreehole.png Here]]
** In ''Mac Anu'', if you run towards a specific spot in a specific wall, the floor suddenly vanishes, and all the other characters fall into the orange void. [[https://www.youtube.com/watch?v=kPHAV8XSgQc Here]]
** Again in ''Mac Anu'', there is a spot in the wall to the east of the dome that, if you ride your steam bike towards it continuously, the bike will start sinking into the floor. [[https://www.youtube.com/watch?v=qvQQw-C45KI Here]]
** Starting from the second game, there are 8 areas (4 on the beach, 4 on the mountains) where the {{Invisible Wall}}s have a small break where you can pass, allowing you to walk into the air/sea. This can be used to fight the Doppelganger without the battle cage. [[https://www.youtube.com/watch?v=mP5EyhP3qis This is how to do it]]. Just make sure you take care to not be hit by a guard breaker that will [[https://www.youtube.com/watch?v=VKnsgEBd8OQ send you flying through said break in the invisible wall]]
** If you use the steam bike while walking in the air, the bike will immediately start falling. If you use it on the sea, you will have a rather crazy run until you hit the water's edge, where you will start falling.
** The area ''Delta: Flattening Ruined Fast Horse'' is pretty famous for its visual glitch. The treasure room is positioned too close to another room, so the two overlap. If you go to said room, it is possible to see a waterfall in the middle of the room! The area ''Theta: Tranquil Black Moon Raven'' has a similar glitch, but not so pretty. Still worth looking, though.
** In the second game, there are 4 areas that, if you use an item to teleport to a platform in a hill, you will end up inside the ground.
** The last floor in the ''Delta: Upfront Starting Berserker'' is completely empty of enemies. There is a Battle Area in there, but if you enter, the victory sequence starts playing immediately without any fight. When you leave the area, it counts as if you didn't defeat 5 groups of enemies.
** The area ''Delta: Screaming Idling Princess'' is a very interesting place. It's a mirror of a quest area, so it doesn't have an objective. The SideQuest NPC, Mecha Grunty, appears on the beach, almost in the water. This is the only area in the whole three games where this happens. The 2nd platform does not appear in the map, and if you try to teleport to it, you can appear below the ground. In the first game, there is a monster called "-" here that should not exist, and doesn't appear in the Book of 1000. This monster drops an item called Healing Portion (portion, not potion), which should not exist in the first game, and also does not appear in the Book of 1000. If you keep this item when converting to the 2nd game, it turns into a regular Healing Potion. Said monster is called Azul Sachem and is only introducted in the second game, due to it being a [=Lv90=] enemy. [[BossInMookClothing Yes, it's a Lv90 enemy that appears in a Lv11 area]].
** In the 3rd game, you can customize your armor with 3 slot Counters[[note]]this gives 50% chance that enemies that attack you will receive 50% of the damage dealt back at them[[/note]]. By the end of vol 3, you can use a character that was lost in the middle of the second game again. By that time, she will be around Level 90, while the last boss is [=Lv130=]. Said last boss has an attack where it'll go around to the background, and then come crashing into the battlefield, hitting everyone. For some reason, if this attack triggers a counter, it will trigger it ''three times''. Due to how the battle system works[[note]]Levels are very important to calculate damage. If the attacker is at least 15 Lvs above the target, it '''will''' hit 9999 damage.[[/note]], if you have said [=Lv90=] character trigger a counter by this attack, the last boss ''[[GameBreaker will be hit by 14997 damage and die instantly]]''.
* In ''VideoGame/ChronoCross'', Lord Viper goes into a secret room in the bar at Termina at one point to receive his level 3 tech, [=FlagBearer=], and an accessory, the Dragoon's Glory. However, if you step into the hall right outside the secret room without going into the main bar area, you can go right back in. Then, if you examine the place where the flag used to be, you will get another [=FlagBearer=] and Dragoon's Glory. The tech is useless to get multiples of, but the accessory is probably the best in the game. You can do this to acquire enough Dragoon's Glories to outfit the entire party.
* ''Franchise/KingdomHearts'':
** In ''VideoGame/KingdomHeartsI'', if you enter Hercules Cup on a timer, pause the game and choose restart the match once you get to Hercules, the fight with Hercules will restart with the timer frozen.
** ''VideoGame/KingdomHeartsII'' has a [[https://www.youtube.com/watch?v=gkuHiNCSDvE bug involving Trinity Limit]] in the original Japanese version that causes it to always inflict the maximum number of combo hits. This makes fighting bosses a joke when you're dealing over 4 bars of their HP with a single attack in under 10 seconds.
* ''VideoGame/BookOfMagesTheDarkTimes'' has a glitch where a single trip to the Mana Cave can grant you more skill points than you're possibly able to spend. In the early game, trips to the Mana Cave are the only way to level up at all; the upshot of this is that you can be almost as strong as the game's BonusBoss before your ''first battle'', completely removing any difficulty whatsoever for the entire rest of the game and allowing you to [[CurbStompBattle curb-stomp]] even the early HopelessBossFight.

* During the InevitableTournament in ''VideoGame/BreathOfFireIII'', you fight the first round in a pit of lava, standing on platforms held by large men called Dodai. You can win either by knocking out all three members of the opposing team or by knocking out the Dodai holding the opponent. The second member of the enemy team, Cawer, casts multiple spells, including Heal and Rejuvenate. Where this comes into play is how the enemy is programmed to fight -- if you focus on their Dodai, they focus on yours. Cawer's AI isn't programmed to differentiate between healing spells and attack spells when attacking the Dodai (only when focused on you), meaning he can and will heal your Dodai if you focus on his.
* In ''VideoGame/TheDenpaMen 2: Beyond the Waves,'' there's the "Local [=DenpaM=]" glitch. For some reason, certain Wi-Fi signals cause the game's random character generator to flip out a little. It starts pulling characters from what seems to be a pre-built "pool" inside the game, which have predetermined appearances and all of whom have the glitchy name "Local [=DenpaM=]." However, all of these characters ''also'' come complete with decent-to-rare equipment already attached (a significantly rarer occurrence in "real" Denpa Men). They can be used to get good equipment early... and in some instances of the glitch, even if the men are caught and released, they will ''always'' appear with their trademark equipment, making them useful money farms as well.
* The first two ''VideoGame/GoldenSun'' games have the Retreat glitch. By using the shoulder key shortcuts to cast Retreat when the character casting it has less than 6 PP, certain parts of the map will connect to other maps entirely. Useful for speed-runs, and for the [[SelfImposedChallenge No Mia Challenge]] (it's used to skip the area where she's recruited).
* ''VideoGame/BetrayalAtKrondor'':
** You're allowed to restore a few hit points by resting during the battle instead of any other action. However, if you press "R" quickly enough (or just hold it), you can rest ''in the same turn'' with any other action. Or rest twice. Casting ''Despair thy eyes'' (the cheapest paralysis spell) would cost no stamina, and using cold weapons would heal characters. Characters can routinely finish a battle with more stamina/hit points that they started with -- wear decent armour, kill all mages and poisoners, then keep defending and resting; you'll need to repair your armour after that, though.
** Late in Chapter 6, the party comes across a well that, according to its description, lets you permanently raise your strength by a few points (which means improved melee damage) if you first dose it with a potion (Fadamor's Formula, which temporarily raises your strength). The original version of the game had a bug where it would take ''all'' of your Fadamor's Formula instead of just one dose. However, a later patch overcorrected the problem, so now the well doesn't take ''any'' doses at all. As long as you start with one dose of Fadamor's Formula in your inventory, you can raise your strength to insane amounts in just a few minutes, turning even your SquishyMage into a formidable melee fighter. (Just don't raise it too high; if it goes over 255 you start doing ''negative'' damage to enemies, healing them instead.)
* ''VideoGame/EyeOfTheBeholder'':
** The ''aid'' spell can raise a character's hit points total above the max, but only temporarily (unless right before a fight, it's unlikely to be of much use). However, damage from a fall mucks up the calculation, and you can end up with more hit points than before for a while, even above your maximum, including after the expiration of the ''aid'' spell.
** The second game has a section where you are meant to relinquish all your spellbooks and cleric holy symbols and get through relying only on physical combat. However, you can open a character's spellcasting menu, ''then'' drop the items, which will still leave the menu open and allow you to use some spells. You can also keep ''one'' such item by holding it with the mouse pointer when entering the section (preferably a holy symbol for healing).
* ''VideoGame/MarioAndLuigiPaperJam'' is already an extremely buggy game, with a list of amusing glitches that numbers almost a hundred in length. However, even this game has some especially useful bugs in it...
** The first and foremost of which is the Instant Battle Glitch. Put simply, [[https://www.youtube.com/watch?v=f3fumNe6n-M if you escape a Toad Mission then fight a boss, losing and retrying will act like you've won the boss battle.]] This leads to a funny situation where the speedrun world record of the game involves the player deliberately killing themselves in every battle to move on.
** [[https://www.youtube.com/watch?v=lGPiv82OMHU There's an amusing bug that lets the player use Paper Mario on their own by escaping a Paper Mario only area with a glitch.]] In this state, he can fight any enemies he feels like, use shops, pick up items and do all manner of things you'd expect a full party to be needed for, turning the game into a ''VideoGame/PaperMario'' type experience.
** Finally, if Paper Mario returns to said area he escaped from, the bros will reappear off screen in the area they last saved in. However, the game also somehow turns off collision detection at this point, so now they can run through walls and solid objects at will. As you can imagine, this breaks a lot of the game. [[https://www.youtube.com/watch?v=lPELka1UtS0 It can also be done with the Starlow cutscene in Mount Brrr.]]
* Similarly to the Final Fantasy V example, the bosses in ''VideoGame/SuperMarioRPG'' sometimes lack the normal boss immunity to status ailments. Specifically, when you knock out one of the other enemies on screen in the fight against Exor, he loses all immunities. ''All'' immunities. Including immunity to Geno Whirl, which can OHKO him if timed correctly.
* The OptionalPartyMember of ''VideoGame/WestOfLoathing'' Buffalo Buffalo Buffalo Bill has a PercentDamageAttack that causes 50% of current HP to any enemy. Occasionally, it will do 50% ''maximum'' HP in damage, killing the enemy. Also, if his attack on one enemy hits a different enemy, it will still use the targeted enemy's HP to calculate damage.

* The sound designers for ''VideoGame/ChronoTrigger'' found a bug in the SNES's sound chip and used it to create Lavos's distinctive roar.
* The first ''VideoGame/{{Geneforge}}'' has a single living tool (series equivalent of a lockpick) found halfway through the game that, as long as it is picked up without any other living tools in your inventory, will be marked with an X (a value usually only held by ranged weapons out of ammo) and, along with weighing nothing, be able to be used an infinite amount of times. The tool disappears if any more living tools are picked up afterwards, but as long as you drop it on the ground before completing any quests that give you living tools, this is easily avoidable.
** Pyroroamers are a creation that [[ActionBomb explode upon dying]], damaging all nearby creatures, enemy or otherwise. Absorbing a creation counts as it dying. If you make a group of Pyroroamers and absorb them, you can cause them to explode on command. This includes ''in friendly towns''. And towns will only recognize you as hostile if you attack them directly. Because of this, you can kill [=NPCs=] without consequence and pick up the items they drop. You can even kill faction leaders to impress rival factions ''without the faction you attacked getting angry with you''. And to top it all off, this glitch works in every game in the series.
** The third game added the ability for you to send creations (or Alwan and Greta, if they are in your party) to steal items. Sounds fine, except for the fact that the game only checks ''the player's location'' when deciding if they get caught for stealing. Because of this, the player can move to a location with no nearby [=NPCs=] and send their followers to steal everything in the area without getting caught. The only things this glitch can't steal are items in containers, which the player needs to directly examine. This is fixed in later games.
* Moraff's ''Dungeons of the Unforgiven'' has Rings of Regeneration which restore 1 health point per ring per step taken. There is a bug in this; if you jog on the spot by pressing [Enter], not only does it count as a step, but you can get more health than your current maximum this way. Just be careful that your health doesn't go over 32,767 and thereby become negative...
* ''VideoGame/{{Minecraft}}'' Hypixel's version of [=SkyBlock=] allows you to fly with DoubleJump and the grappling hook item, [[https://youtu.be/vLLJAiII6p4?t=394 as discovered by]] ''{{LetsPlay/Technoblade}}''.

** You can bypass the gate to Sen's Fortress by using abusing death triggers. Death by falling into a bottomless pit (or similar) in the original game consists of two parts: the game going into a top-down view in order to display you falling to your death, and the game killing you proper. The former can be triggered without progressing to an actual death (such as using a parry to clip into the stairs before the building containing Andre the Blacksmith and the Undead Parish bonfire). Doing this causes the gate into Sen's Fortress to not load at all, allowing you to walk past it without ringing the Bells of Awakening.

** A particular infamous example is the off-hand bow glitch, which is very similar to the tumblebuff swap glitch from the first game. This can result in tons of different effects from faster weapon attack animations to instant spell casting, and most infamously turning a Great Bow into a Great Automatic Crossbow, allowing for shenanigans such as ''one-shotting the final boss''.

** Remember how Bone Ash enchanted Cannons were the bane of low Blood Level [=PvP=] characters? Now imagine if they had an unlimited load of those silver bullets with the [[https://youtu.be/N44Pv5jeeFI Rapid-Fire Cannon]] glitch, which requires a specific series of commands to execute. This would have been the precessor to the infamous off-hand bow glitch in ''VideoGame/DarkSoulsIII'' had it been not been discovered several years after release, and can [[https://youtu.be/g_Ev3jskwVA easily cheese]] even the ''Orphan of Kos''.

** Carian Retaliation was a solid spell parry in the initial versions of the game. Once you deflect a spell, Carian Retaliation would cast Glintblade Phalanx, summoning three invisible (except to you) magic swords that hover over you and home in on the nearest enemy after a delay. Good on its own, but nothing special. Then the 1.03 patch introduced a major bug with Carian Retaliation that caused it to scale tremendously with your shield upgrades, easily dealing thousands of damage per activation off a maxed out shield and melting the HP of any boss or player, all while safely firing shots from a distance. It's actually pretty easy to exploit as well, since you can parry ''your own spells'' or even consumables like the Wraith Calling Bell to get the swords. This set-up is so powerful that nothing, not even the game's {{Superboss}}, can actually stand up to it, killing most bosses in less than a minute with minimal risk to the player. In PVP, the Ash of War produces ludicrous damage that one-shots players and is very hard to dodge, with the only telegraph being the sounds of the item being used to create the projectiles being "parried". The 1.04 patch addressed this by removing the abnormal damage scaling so that players no longer get one-shot off this Ash of War.

** The game has a failsafe that prevents players from getting stuck by instantly killing them if they're trapped in the "falling" state for too long. This failsafe works for ''every'' entity, including bosses. There are stories of tough enemies unintentionally getting caught in a tree and dying from this failsafe.
** As in previous [=FromSoftware=] games, the player can mash buttons to struggle out of some enemies' grab attacks, causing the enemy to drop them more quickly and resulting in less damage taken. For some reason, doing this to a Runebear causes it to phase straight through the floor. Provided there's no other floor beneath it, it will end up outside the map and die to the aformentioned failsafe. Considering Runebears are some of the most aggressive and tanky enemies in the game, not only is this far more effective than actually fighting them, but [[RuleOfFunny it's also just hilarious]].

** Before it was patched, it was possible to [[https://www.youtube.com/watch?v=6lABNhKY2XU get into Mohg's arena around the fog gate]] with a well-placed jump off a gravestone, similar to the fog gate glitch from the first ''Dark Souls''. As this would cause Mohg's boss AI to not activate, this essentially made the boss trivial.

** Although the circumstances surrounding it are still unknown, it is possible for the Regal Ancestor Spirit's teleport manoeuvre to malfunction and transport him out of bounds, wherein he's instantly killed by a failsafe.

** For some reason, entering NewGamePlus results in the player running around various swamps and lava without getting their movement impeded. This is most notable in areas where you cannot ride torrent, and makes navigation much more of a breeze.

** You can bypass the gate to Sen's Fortress by using abusing the triggers for death in this game. Death by falling into a Bottomless Pit (or similar) in this game consists of two parts: the game going into a Top-Down View in order to display you falling to your death, and the game killing you proper. The former can be triggered without progressing to an actual death (such as using a parry to clip into the stairs before the building containing Andre the Blacksmith and the Undead Parish bonfire). Doing this causes the gate into Sen's Fortress to not load at all, allowing you to walk past it without ringing the Bells of Awakening.

* ''VideoGame/PokemonScarletAndViolet'' was clearly [[ChristmasRushed rushed for a November 2022 release]], and the results speak for themselves. On launch, people quickly took to social media with clips of severe framerate drops, animations glitching, characters appearing and disappearing at random, {{Player Character}}s clipping through the map, and various other anomalies. Comparisons to ''VideoGame/SonicTheHedgehog2006'' were inevitable due to the sheer amount of bugs and how outright bizarre they would get.

*** There is another funny and less-powergaming bug with the Orphan of Kos as well; if you somehow manage to do enough damage to kill the boss outright before he goes into phase 2, the Orphan will freeze in place and stare at you instead of doing its death animation, as the developers had not accounted for the boss dying before changing phases. Fortunately this is more humorous than anything, as the game will still count it as a victory after a few seconds.

** Speaking of the Orphan of Kos, there is a very cheesy glitch where if you manage to Visceral Atttack him on one of the rocks around the arena and start phase two of the fight, the boss's AI will freeze completely, making him completely trivial.
*** There is another funny and less-powergaming bug with the Orphan of Kos as well; if you somehow manage to do enough damage to kill the boss before he goes into phase 2, the Orphan will freeze upright and stare at you instead of doing its death animation, as the developers had not accounted for the boss dying before changing phases. Fortunately this is more humorous than anything, as the game will still count it as a victory.

** Father Gascoigne has a number of bugs that can render him trivial. It's very easy to get him stuck between a tree and a statue, allowing you to wail on him with impunity. It's also possible to glitch him out of the map boundaries by using a Visceral Attack on the stairs, killing him instantly.

** A difficult but absolutely ''bonkers'' glitch allows you to gain [[https://www.youtube.com/watch?v=ZXGE6JKJUk4&t=163s tens of millions of extra Echoes from bosses by stacking Heir runes]] thanks to the way the game caculates Visceral Attack overkill damage. This glitch technically works on any boss, but it's easiest to do on Living Failures in the DLC and also gives the most Blood Echoes. Equip the Heir Runes and finish the boss battle with two consecutive visceral attacks within a time window of 6 seconds. What happens on the Living Failures in particular is that it the killing blow is applied to all of them at once but counts multiplicatively with three stacked Heir Runes as the Living Failures technically share a single healthbar. The results in a boss that normally gives about a hundred thousand echoes instead giving you roughly ''68 million'' echoes. On New Game+6? Try ''''660 million''' Blood Echoes, enough to almost level your character to the level cap.

*** One of the most famous glitched Chalice Dungeon glyphs is "''cummmpfk''" (sometimes jokingly called the [[FanNickname "Cum Dungeon" or "Cum Chalice" by fans]]). The very beginning of this chalice spawns an inactive Hunter NPC in front of a pendulum trap within the game's rendering distance, where the trap will eventually kill the NPC on its own without the player having to do anything. This instantly gives the player roughly 100k Blood Echoes on the spot, and the NPC Hunter will respawn if you leave the chalice and come back, turning this into the best Echo farming spot in the entire game by a huge margin.

** The Ashes of War "Determination" and its more powerful version "Royal Knight's Resolve" apply a buff that makes a single attack deal more damage. However, this buff affects ''all'' damage you do, but is only consumed after landing a hit with the buffed weapon itself. If you buff your left-hand weapon, you could attack with your right and get the damage bonus on ''every'' hit, or even boost your spellcasting damage. It does wear off naturally after a short time, but is very quick to reapply whenever you need to. Determination is also available almost immediately by killing a Teardrop Scarab north of Agheel Lake. This interaction was corrected in the 1.03 patch to affect only the weapon with this skill.

** A very useful bug allows you to cheese the final Hunter fight of Eileen the Crow's questline, normally an [[ThatOneBoss extremely difficult battle]]. When the Hunter switches the form of his Chikage, using a Blue Elixir and running away will cause him to lose track of you and return to his starting point. However, the Chikage's alternate form also drains health, so he'll simply stand there until he dies (and he won't heal because his AI isn't technically in combat anymore).
** Remember how Bone Ash enchanted Cannons were the bane of low Blood Level [=PvP=] characters? Now imagine if they had an unlimited load of those silver bullets with the [[https://youtu.be/N44Pv5jeeFI Rapid-Fire Cannon]] glitch, which requires a specific series of commands to execute. This would have been the precessor to the infamous off-hand bow glitch in ''VideoGame/DarkSoulsIII'' had it been discovered years earlier, and can [[https://youtu.be/g_Ev3jskwVA easily cheese]] [[spoiler:''the Orphan of Kos'']], widely regarded as one of the hardest boss fights in the game.
