Tainted Cain is an unlockable character in The Binding of Isaac, added in the Repentance DLC.

Bag of Crafting (consumable slot)

Can only shoot tears from his right eye.

Cannot pick up any items and must use the Bag of Crafting to obtain them.

Touching an item pedestal will convert it into an assortment of pickups. An exception to this rule are items with the quest tag.

Specific pickups are dropped when touching items based on the current room:
• Secret Room: Bone Hearts
• Curse Room: Rotten Hearts
• Planetarium: random runes
• Devil Room: Black Hearts
• Angel Room: Eternal Hearts
• Ultra Secret Room: Cracked Key

Crafting an active item will transform the old active item into pickups instead of dropping it.
