Loot Tokens
From Wyvern Source
Loot Tokens are a form of currency used to claim items dropped during a Lootsplosion, from Yojimbo's Pawn Shop, from a slain Yojimbo, or at the end of a Live Quest.
Loot Tokens can be earned from daily login rewards, from killing Onyros, from slaying Yojimbo, or from slaying a Live Quest boss.
