Chaos is a passive item added in The Binding of Isaac: Afterbirth.

Effects

• Drops 1-6 random pickups around Isaac.
• Causes items to be chosen from random item pools.
  • Fixed item drops that ignore the current room's item pool will not be replaced. Examples include Cube of Meat after defeating one of The Harbingers as a floor boss, or The Small Rock after breaking a Tinted Rock.

Notes

• When playing Greed mode, items that are available only in the normal game will still not appear despite Chaos; the modes' different item pools stay separate.
• As the item does not mix or combine item pools, it is possible to quickly deplete smaller item pools and end up with Breakfast.
  • Thus, if Chaos tries to pull from an item pool that is already depleted, it will not pull from a different pool and instead give you Breakfast.
    • As many Greed mode item pools are small, Chaos tends to result in Breakfast more often during Greed mode.
• Since all item pools have the same probability of being selected, bomb-related items are much more common due to the Bomb Bum item pool.
• If an item outside of the Devil Room pool appears as a Devil deal, it will always cost 1 Red Heart container (or 3 Soul Hearts should Isaac have no Red Hearts).

Interactions

• Sacrificial Altar: Sacrificial Altar ignores Chaos's effect and always generates from the normal Devil Room pool, even on Greed Mode.

Gallery

• 

  The Forgotten gains a unique appearance from Chaos. Rather than the troll face grin, The Forgotten's grin is larger, fully showing his teeth (likely due to being skeletal), and the smile is even across both sides of his face.

Trivia

• The item's sprite is a Symbol of Chaos.
• The character appearance is similar to the "Trollface".
