Devil Room (Item Pool)

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 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 Hearts / Black Hearts. 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 Chaos or exhausting the item pool, making Breakfast appear. The exceptions to this are items that cost 30 cents in Angel Shops from The Stairway, and R Key, which cost 2 Red Hearts, 1 Red Heart and 2 Soul Hearts, or 3 Soul Hearts.
