While not in a Raid or Dungeon every 15 sec sec while in combat, you apply 5 stacks of Ula'tek's Gift to the target with the highest amount of Ula'tek's Gift applications. Otherwise afflict the highest health enemy. Ula'tek's Gift Deal X Nature damage per application every an effect-defined interval sec for 1 min. Upon applying 20 stacks to a target, the Gift corrodes, dealing the remainder of its damage immediately before removing itself.
