Corkian Amplifiers are a Legendary Corkian Augment introduced in the 1.20 Gavel Reborn update which can be used while Identifying or re-rolling items to improve the rolled Identifications. Corkian Amplifiers are primarily obtained as a reward from Raids; four Tier I Amplifiers are also given as a reward for completing The Feathers Fly Part II quest. Unlike other Raid rewards, Corkian Amplifiers are not Soulbound and have no minimum combat level, so they can be bought and sold on the Trade Market and used at any level by any class.
