Consumable

A consumable is any item that has a special effect when used. All consumables require the player to double-click the icon to activate. Regular consumables are stackable and disappear after one use; some have multiple uses and don't stack, such as kits. Some have unlimited uses, such as everlasting tonics.

Consumables that grant a buff don't stack if used twice. Consumables cannot be used in PvP.

Types
Most consumables can be classified by effect:
 * Alcohol causes drunkness, which can add points to the Drunkard title.
 * Dye changes the color of specific items, usually weapons or armor.
 * Festive items create a visible animation on use and add points to the Party Animal title.
 * Food is a theme common for consumables.
 * Kits, having two types, either identify or salvage other items in the inventory.
 * Presents grant one of several things depending on the consumable and random chance, including items, gold, or blessings.
 * Scrolls create a Party Bonus that increases the experience gained per kill.
 * Skill tomes are used to learn profession-specific skills unlocked on the account.
 * Summoning stones summon a temporary ally for the party.
 * Sweets usually cause a speed boost in towns or outposts and add point to the Sweet Tooth title.
 * Tonics change the appearance of the user to a tonic-specific model.

Some miscellaneous consumables include those from Eye of the North crafters, which grant Morale Boosts, buffs to health, energy, and speed, and even resurrection.

Trivia

 * Identification Kits and Salvage Kits were the first consumables in the game.
 * The term "consumable" found use with the introduction of Consumable item crafters in Eye of the North.
 * For that reason, the player term "consumable set" (or "conset" for short) refers to a trio of items offered by those NPCs, namely a Grail of Might, Essence of Celerity, and Armor of Salvation.
