Anduin summons a Befouled Barrier that inflicts X Twilight damage to all players and creates a barrier that persists for 30 sec. X% of healing received by players within the area is redirected to the barrier. Up to X healing received reduces the size of the barrier. Upon expiration, the barrier explodes and inflicts X Twilight damage, tainting all players. This effect absorbs up to X healing received based on the size of the Befouled Barrier.
