Alkar's Concoction

An item given by High Priest Alkar when the quest The Destroyer Challenge is taken. When in the area of a Destroyer, double-clicking this item will deal 100 damage to all Destroyers in the area. Only one Concoction can be used by each player in one minute.

Although the new skill that completing The Destroyer Challenge rewards, Alkar's Alchemical Acid, deals more damage than Alkar's Concoction, the latter does not take up a skill slot, and has a larger range. Those who are patient can repeatedly accept and abandon the quest, putting the Concoctions into storage or just drop a stack from your Inventory before accepting the quest again to build up a supply.
