Loot

Loot is the collective term for various items, abilities, and currency that can be found or awarded to Guardians for completing quests. Before being collected, loot appears in the world as glowing polyhedra. Defeating bosses will reward Guardians with rare loot, such as exotic weapons and armor. Loot can also be found in chests hidden around the world; many include glimmer, but some also include a piece of gear. Items and weapons may be traded between player characters under a single account by use of a vault, armor can only be used by the class it is designed for, at this time nothing can be traded between different players within the Tower.
