*** You can't even start progression into world 4 without finishing the skill tutorials for world 4.
** In order to get the respective bosses's key, you have to do some quests from [=NPCs=] near the boss door and completing them with each new character will increase the number of keys obtained. Averted with the fourth world, as the key is a random drop from the last enemy on the area.

*** The Infinity Signs will allow all of your characters to have a star sign bonus active, regardless if you have it activated or not, while also not giving you the negative downsides. The catch is that you have to obtain more infinite signs from levelling up specific shiny pets.
*** The Skill Mastery makes so that all the combined levels of the characters grants you a bonus, such as more efficiency, skill EXP, printer output and specific skill bonuses. Chopping, Mining, Fishing, Catching, Trapping and Worship in particular will also make their materials's cards passive. Construct Mastery is obtained later, but grants more benefits, such as more levels for your buildings.
** The Monolith's second quest, "Onyx Statue Crafting", will require you 20000 Power Statues, which is also the requirement to upgrade a statue into onyx. Completing the quest will have the Monolith take your Power Statues, but will also upgrade said statue to onyx as well.

* CreatorCameo: [=LavaFlame2=] himself plays the game and can be encountered since it's a MMO. He's easily recognizable since he's twice as big as the other players.

** When you first talk to Bandit Bob, he immediately shoots you dead. However, if you talk to him and then IMMEDIATELY start climbing the rope, you instead survive AND get enough Bandit Bob cards to instantly reach 3-star rank, and only need to do it once more for 4-star. This is important because without doing this you cannot max out the [=YumYum=] Desert card set.

** The Nuget Cake Hat requires looting a 1/20000 Nuget Cake drop from Crabcakes while fully active. This means no auto at all. Considering that even "active play" in this game means throwing on auto-battle and letting the game run in the background, this one can be rather tedious if you don't luck out during a Colosseum run.

* PinataEnemy: Crystal mobs have a chance to replace a normal monster when actively fighting. They have higher stats, but award extra experience, money, and drop items from multiple rare loot tables at once. Typical endgame strategies involve maximizing Crystal spawns to generate loads of statues, experience, and/or money.

** Played straight with Pre-Crime Boxes, the counterpart that only appears when you equip the Level Up Gift alchemy Bubble during a specific quest. Despite being labelled as "Quest Item", it doesn't do anything, and is not a requirement for any quest. They're also sold for a measly silver coin, at a point where you would likely get gold or platinum coins.

* PropellerHatOfWhimsy: The Beginner class is represented by a character wearing a propeller cap on its portait to represent them being a inexperienced newbie.

* DoubleUnlock: A lot of systems require you to unlock something and then spend either resources or time to actually activate it, to the point where it's easier to list what DOESN'T do this.

** Boss wings have anywhere between a 1/1000 to 1/4000 drop rate, and only drop from the hardest difficulty. For the first three bosses, you are timegated behind a daily income of keys, of which it takes days to get enough for one run. Ironically, this actually makes the Troll cape the easiest to farm because you can use Elemental Sorcerer and Divine Knight to farm tons of keys.

** Blood Berserkers get access to the Cooking skill shortly after entering the Hyperion Nebula. Unlike other games with a GameGourmet mechanic, meals specific to the Cooking skill are treated more like skill points rather than consumables. Meals are cooked up after waiting out a timer, then are "spent" by setting the table next to the kitchen, which grants passive bonuses to all characters on the same account.

* ObviousRulePatch: Sailing has been hit with a couple. Originally, you could press Escape to open the main menu and "pause" the Sailing progress, letting you cut up a big afk session into small chunks and claim a lot more chests than intended. It was patched so you could no longer use hotkeys while your Sailing gains were playing out, and patched again when it was discovered that clicking at the blank space above the map achieved the same result. Technically it's still possible to do the trick[[note]]you have to input a chat command that warps you do a minigame map while the Sailing animation plays out[[/note]] but the tedium and difficulty in doing it precisely make it no longer worth it.

** One perk that the Maestro class has is called "One Step Ahead". It's pointless to level up that perk, as it currently does nothing at all.

*** Played straight with Pre-Crime Boxes, the counterpart that only appears when you equip the Level Up Gift alchemy Bubble during a specific quest. Despite being labelled as "Quest Item", it doesn't do anything, and is not a requirement for any quest. They're also sold for a measly silver coin, at a point where you would likely get gold or platinum coins.

* ShoutOut
** The mastery mechanic is inspired by Maple Story, as evidenced in the third passive green alchemy bubble. [[note]]"Mastery is your stat that boosts minimum damage. Just like in Maplest... err, just like how I thought it up myself!"[[/note]]

** The largest amount of resources you can obtain is 1000M. Any exceeding material will be converted into atoms should you have the Atom Collider.

** Once you built something for the first time, you'll get the option to craft it by using materials in your storage.

** Obtaining certain achievements allows you to claim boss keys from the Quick Ref menu, saving you a bunch of teleports and time.

** When you first talk to Bandit Bob, he immediately shoots you dead. However, if you talk to him and then IMMEDIATELY start climbing the rope, you instead survive AND get enough Bandit Bob cards to instantly reach 3-star rank, and only need to do it once more for 4-star. This is important because without doing this you cannot max out the YumYum Desert card set.

* ImpossibleItemDrop: Some mobs drop questionable loots (like poops dropping corn kernels).

* ObviousRulePatch: Sailing has been hit with a couple. Originally, you could press Escape to open the main menu and "pause" the Sailing progress, letting you cut up a big afk session into small chunks and claim a lot more chests than intended. It was patched so you could no longer use hotkeys while your Sailing gains were playing out, and patched again when it was discovered that clicking at the blank space above the map achieved the same result.

*** Desert Davey, Iceland Irwin and Nebula Neddy will prevent access to their respective world's tasks until you complete their quests. Grassland Gary on the other hand will lock you out the tasks on a new character until you get to level 14.

* AchievementSystem: You get achievements for doing specific things, which can be seen in the tasks. They usually range from requiring an exact amount of specific items in your deposit, killing certain enemies in a time limit, or complete some minigames with a condition.
* AdamSmithHatesYourGuts: As you progress through the game, the requirements for skilling, crafting and mobbing becomes much more demanding. The first ore you mine, copper, requires 7.5 mining efficiency to mine. The third ore, gold, requires 312.5. By the time you reach void ore (the sixth one), you will need at least 150k efficiency to even obtain one. Not to mention the increasing number of skills you need to manage after each world. By the midgame, this game can hardly be considered an idle game anymore.

*** The Trapper Drone is essentially an in-town version of the Hunter's "Eagle Eye" talent, allowing you to place traps and collect critters without having to visit their specific map.

** The Slush Skull falls into this when it comes to the Worship skill. It gives 1000% max charge, and a 2% on all stats just for a requirement of level 10 in Worship. However, the speed of 2 means it generates Charge abysmally slow, and without upgrade slots you generally do better on stats by chucking World 4 or later souls at a higher-tier skull. As Worship is a skill that every character participates in, equipping Slush Skulls will greatly hinder soul gain. They do find use as a crafting ingredient for the world 5 Dreadnaught Skull at least.

* CantCatchUp:
** Once you start gathering new healing food and potions, you have no reason to use the old ones unless it's for an upgraded food pouch.
*** Unlike the Small Mana Potions and Small Life Potions (which can be used in few smithing recipes), Small Speed Potions and Small Strength Potions do not have any use for smithing recipes, and as a result become utterly pointless to collect.
