Consumables

Consumable is the word the game uses to describe an item that can only be used once, or that has a random chance of being unrecoverable after use. If such an item is "consumed", it is gone forever. Importantly, this term is distinct from Category:Consumable items, which encompasses all items which can leave the player's inventory upon use, but which are not necessarily destroyed or "consumed". The category is (at least theoretically) a superset of items labeled in-game as Consumable.
