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 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.
