Items

**Items** are an integral part of the gameplay 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.  *Afterbirth* added 95 new items, for a total of 436 items.  *Afterbirth †* added 111 new items, for a total of 547 items.  *Repentance* added 169 new items, for a total of 716 items. An update for Repentance, V1.7.5, added 3 new items, for a total of 719 items. In *Afterbirth †* and prior, 13 items are considered special and will be less likely to appear if the player has already come across other special items. The *Repentance* expansion removed the Special Item mechanic, replacing it with the item weight and item quality mechanics.

For a list of which items can potentially appear in a given special room or under certain conditions, see item pool and Item Tags.

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 , 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 ), 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.

 In some special circumstances, activated items can be placed in the consumable slot instead of the standard activated item slot. This counts as both an extra activated item slot and an extra consumable slot, meaning that other activated items and consumables can be picked up as normal. Items in this slot are used with the consumable key, and can't be lost through any means (unless they're consumed like items from ). Otherwise, they function the same as other activated items.

### Notes

* Battery Bums and most Batteries charge the item(s) in the activated item slot first, then the item in the consumable slot. The exception to this is the  Mega Battery, which recharges the items in both slots.
* Most trinkets that work with activated items (e.g. , , etc.) ignore the items in the consumable slot.

## Passive Collectibles

Passive collectables are vast and diverse, varying wildly in effect and strength. Some simply improve Isaac's stats, add health, or provide a familiar. Some completely change the way the run can play.

* Other common effects include:
	+ Isaac's tears gaining Tear effects or causing Status Effects on hitting enemies.
	+ Isaac's tears being replaced with a completely different weapon, such as a knife.
	+ Isaac's bombs gaining new effects, often with a bonus supply of extra bombs.
	+ Triggering a special effect when Isaac takes damage, or kills an enemy.
	+ Creating additional pickups, either when first collected, or over time.
	+ Improving active item cooldowns.
	+ Granting permanent flight.

An unlimited amount of passive collectibles can be held at a time, and the effects they grant usually last until the end of that run.

* Removing a passive item is only possible in a few rare ways, and usually comes with severe drawbacks, such as  and  rerolling *all* passive items, or  removing the last passive item collected at the cost of changing the active character.

* Tainted Isaac is limited to 8 passive items (12 with ) at a time, and can freely swap out old passive items once his inventory is full.

Nearly all passive collectables alter Isaac's appearance when collected, with newer items replacing the cosmetic effects of older items.

## Collectible ID Gaps

All of the collectibles in the game have contiguous IDs, with the following exceptions:
