Befouled Barrier

Anduin summons a $@spellname365293 that inflicts 35 Twilight damage to all players and creates a barrier that persists for 30 sec. 50% of healing received by players within the area is redirected to the barrier. Up to 450 healing received reduces the size of the barrier.

Upon expiration, the barrier explodes and inflicts 100 Twilight damage, tainting all players. This effect absorbs up to 1 healing received based on the size of the Befouled Barrier.
