Gizmo

A gizmo is a type of item that has a special function, typically preserved or combined/transformed after use. For example:

• An endless tonic can be re-used, in contrast to its one-use consumable counterpart.
• A Black Lion Key can be used to unlock a Black Lion Chest.

Types of gizmos

• Container gizmos — use a vendor-like UI and use their own as exchange items, e.g. Commander's Choice Chests and some other WvW boxes
• Lore books — books that offer lore and information to the player via dialogue boxes or an audio play-back
• Portable exchangers (also called "converters" or "gobblers") — use a vendor-like UI to provide rewards in exchange for a currency or item
• Teleportation devices, e.g. Portal Scrolls and Lounge passes
• Novelties — Chairs, musical instruments, music boxes, held items, toys, and endless tonics — can be unlocked in the hero panel as novelties for the whole account or kept in the inventory as gizmos for a character
• World versus World Blueprints, Traps, and Tricks, including the Mist Sentry Turret. — although these items are classified as gizmos, they behave more like consumables
