Consumables

A Consumable is an item that is removed from a player's inventory upon direct use. For items that are consumed from use of another item, see Ammunition. Some consumable items, like thrown weapons, may be recoverable as dropped items afterward in certain situations.

There are some consumables that only cause a cosmetic effect such as the Sparkle Slime Balloon. These have no effect on gameplay but are there for fun.

Note: This term is distinct from Category:Consumable items, which is a Terraria Wiki category encompassing all blocks and furniture that can leave the player's inventory via placement, but which are not necessarily used and destroyed.

Permanent boosters
Some consumables will permanently increase a character's stats or cause other permanent effects. These upgrades will never go away, even after death.

Summoning items
Some consumable items will summon bosses or events under the correct circumstances. If used under invalid circumstances however, in most cases the item is not consumed.

Note that many bosses and events can also be summoned by interacting with the environment in other ways or spawn naturally once certain criteria are fulfilled.

Critters
A critter caught with a Bug Net or will drop as an item. Using this item will spawn a living version of the critter.

Potions
A wide variety of potion items are available. Neither healing potions nor can be consumed while affected by the Potion Sickness debuff.
