Demon Heart

The Demon Heart is an Expert Mode consumable item from the Treasure Bag dropped by the Wall of Flesh. It gives the player a sixth accessory slot to use. This effect does not stack and may only be used once per player. When not in Expert Mode, any item in the slot will have no effect. The slot will be grayed out if it has an item in it, or will disappear if the slot is empty, however the disapeared slot will return if you go back to an Expert Mode world.
