Chaos Device

Awarded for completing the Chaos Device sidequest from Dr. Beanies. During the quest, level-ups offer skills from all classes instead of just the cat's own class, creating wildly unpredictable builds. Completing the quest unlocks the Chaos Controller, which also unlocks all classes when leveling up and lets you reroll skill choices up to three times per level-up.

Tip: The quest version is chaotic but can produce incredible cross-class combos if luck is on your side. The Chaos Controller reward is one of the most versatile items in the game, letting you cherry-pick the best abilities from every class with its reroll mechanic. It opens up entirely new build possibilities that are normally impossible.
