Good Bad Bugs / Tales Series

• Tales of Eternia:
  • There are two particularly famous bugs. The first being the "Jump Cast" glitch where by jumping and then rapidly shortcutting to a spell, the magic user you're playing as would rapidly cast said spell for little cost, making certain battles much easier. The other is the "Move Scroll" glitch where by using the scroll feature on your skill lists when they had more than one page, allowed you to access attacks and spells that the character normally wouldn't be able to use. Having Reid with Prism Sword for example, a spell which is only usable by certain bosses. Sadly, the first glitch was fixed in the PSP port, but the second one remained, surprisingly.
  • The Jini Auction glitch, which allowed you to auction a low-value or worthless item, leave the area, reset, and go back to have your item be able to be sold for millions and millions of Jini when normally it should only go for a little more than it is worth. Not only is this the best way to farm gald in the game, but it allows you to easily buy the best accessories in the game very quickly.
• Tales of Destiny 2 has the Title Glitch. This game was the first Tales game where equipping different titles would affect a character's stat gains upon leveling. So that you didn't accidentally make your characters have awful stats, the game would not let a base stat have negative growth, reducing any negative growth to zero instead. When you switched a title, however, the game could forget it had reduced your negative stat to zero. For example, equipping a title that had -6 when you only had a +2 growth stat would reduce it to 0 instead of -4. When you switched the title, the game would add +6 to counteract the -6 from the previous title, making your new growth stat +6 rather than +2. With the large amount of titles and customization available, this could be exploited to nullify a character's weak stats, making everyone into ultra-accurate, ultra-evasive Lightning Bruisers. Fixed in "The Best" version of the game.
• Tales of Symphonia:
  • The game had an interesting skill system where each skill basically had two different skill trees, but the skills from each tree were mutually exclusive. There was a glitch, however, that allowed characters to learn the highest-level skills from both trees at once, which was especially useful for the resident magic-user, Genis. Sadly, this glitch was fixed in the PS2 remake.
  • The game also included passive bonuses from a sort of item slot system, one of these bonuses was the "Randomizer" bonus, which would give a spell sometimes a chance to cast instantly, or make it take longer to cast. The player could easely abuse the fact that a spell can instantly be cancelled and then be recast as well without any lag to throw the strongest spells at anything with instant cast times.
  • The game has hidden Relationship Values. Obviously this should apply only to the other characters, but due to a bug you can make Lloyd become a total narcissus. He falls in love with himself if you have him cook himself food he likes, or dislikes himself if he cooks things he dislikes. This does nothing, but is amusing nonetheless.
  • It's also possible to make the character with the highest Relationship Values appear in one scene and give a line even if they are not in your party, one of which can do this even if they're dead. (One character can die during the course of the game depending on your choices.) Detailed here, under "Affection Related Quirks". SPOILERS.
  • The PS2 port of the game introduced the same world map glitch as Tales of the Abyss, allowing you to travel to places on the map you shouldn't be able to access yet.
  • The "move scroll" glitch from Tales of Eternia was re-introduced in the PS3 and PC ports of the game by switching from auto mode to manual mode while trying to change an attack slot, allowing anyone to equip and cast their Mystic Artes outside of overlimit.
• Tales of the Abyss:
  • There was an interesting glitch that allows you to play as Asch longer than you're supposed to. From time to time, you switch from the Designated Hero Luke to the Anti-Hero Asch. During a sidequest in mushroom forest, if the player ejects the DVD but keeps the game running and have Asch exit the other way, he'll be able to exit the forest, go through mountains, go to a city, save the game, and continue with the main story, as Asch. There are no side effects in doing this aside from a few weird moments since the lines that are supposed to do with Luke is switched, so the player can complete as Asch. It is sort of advantageous, since Asch, unlike Luke, is a Magic Knight, though later on, his usefulness decreases.
  • Finishing the game while playing as Asch using a glitch will make it so, when you start the New Game Plus, you won't have Luke on your party, so the game will always freeze on the tutorial battle, as you won't have any character in your party. Turns into a Game-Breaking Bug if you saved the finished game data on the same slot, as you're now trapped forever before the tutorial.
  • There are other numerous bugs that weren't fixed during the lengthy American localization. One such bug is opening the Disc Door while on the world map. It enables you to travel anywhere on the world map, and you can even pick up hidden items that you would have missed past the Point of No Return. Another bug would be sealing the hidden boss Nebilim's Mystic Artes using Anise's Dying Moon, which is bugged and stops any Mystic Artes from being cast for the entire battle after it is used, so she can't use her deadliest attacks on you.
• Tales of Graces keeps up the good glitches with one that lets you use your Blast Calibur over and over again. Observe.
• Tales of Hearts for the DS, due to having a 2D battle system, if you jump and then attack normally again and again will Shing kinda float and stay there. The enemy gets stuck and can't fight back so you can stay there and buttonmash until the enemy is defeated and you fall down. It works really well against flying enemies, but can be used against shorter as well.
• Tales of Xillia: Due to an oversight, Milla can jump higher than enemies can target. She also has a skill that will allow her to cast magic in the air. This can allow her to become an invulnerable caster.
• Tales of Arise: In the PC version of the game, there is a bug that can occur in the Zionne mine tunnels (aka the second location you go to in game). Since the mine connects to a late game area, the developers created a barricade to prevent players from getting to it. However, if you adjust the vsync and jump towards the pathway, you can get over the barricade and into the area. While the enemies are too high level to be winnable, you can get high level armor for Shionne that will mean she can go 75% of the game being more tanky then every other character due to the fact the armor gives almost 300 extra points of defenses to her. Detailed here.
