Vaal Detonate Dead - 20% Quality, Level 21

Targets a corpse, and deals spell damage to enemies around the corpse, as well as causing the corpse to explode, dealing fire damage. The explosion is not affected by modifiers to spell damage and cannot be reflected. This will continue to target other corpses in the area, with an increasing delay between each one, until it runs out of corpses or has destroyed 22 corpses.
