This article is about the item pool. For the room, see Devil Room.



The Devil Room pool is the pool of items that can be found in the Devil RoomDevil Room and can be given from Hell Games. All items can be bought for some number of Red Heart containers (In the case of the Devil Room). If Isaac has no Red Heart containers, items can be bought for three Soul HeartSoul Hearts / Black HeartBlack Hearts. (in Repentance) Occasionally, items may cost Soul Hearts even if Isaac still has Red Hearts.

Any items outside of the Devil Room item pool will have a price of 1 Red Heart or 3 Soul Hearts/Black Hearts. This can be caused either by obtaining (except in Rebirth)Collectible Chaos iconChaos or exhausting the item pool, making Collectible Breakfast iconBreakfast appear. (in Repentance) The exceptions to this are items that cost 30 cents in Angel Shops from Collectible The Stairway iconThe Stairway, and Collectible R Key iconR Key, which cost 2 Red Hearts, 1 Red Heart and 2 Soul Hearts, or 3 Soul Hearts.
