From Binding of Isaac: Rebirth Wiki
Jump to: navigation, search

Items are an integral part of the game-play of The Binding of Isaac: Rebirth. They modify Isaac's attributes, grant or modify tear effects, and much more.

Items are classified into several distinct types and groups. Some items are passive, which add an effect permanently to Isaac, while others only activate when used. The original The Binding of Isaac had 196 items. Rebirth has a total of 341 items. Added in Afterbirth Afterbirth added 95 new items, for a total of 436 items. Added in Afterbirth † Afterbirth † added 111 new items, for a total of 547 items. Of those, 13 items are considered special and will be less likely to appear if the player has already come across other special items.

For a list of which items can potentially appear in a given special room, see item pool.

For the grids of items that appear in the stats menu, see Collection Page.

Not to be confused with cards and runes, pills, and trinkets.

Activated Collectibles

Unless the player has Added in Afterbirth †Schoolbag Schoolbag, only one activated item can be held at a time, with the old collectible being placed on a pedestal if a new activated item is picked up. Most activated items need to recharge before use, with the recharge bar filling either by clearing rooms or recharging over time. Other activated items do not have a charge bar, and, with a few exceptions (such as How to Jump How to Jump), will instead either disappear after a single use or require resources such as coins or health. Some activated items will also grant passive effects as long as they are equipped.
