? Card: Activates the item without consuming it, allowing for potential multiple uses.
Diplopia: Spawns two Eden's Souls that will both drop 2 items when used.

Car Battery: Does not affect Eden's Soul, only two items will spawn upon use.
Void: If absorbed, Eden's Soul is stored, and allows for a single use in a desired location. Also effectively reduces charge time to 6 rooms
