Effect The hazard rolls initiative.

Routine (1 action) On the hazard's initiative, a boil erupts from the ground and bursts. This blast strikes as many enemies as possible in a 15-foot burst anywhere on the isle, dealing 5d8 force damage (DC 26 basic Reflex or DC 26 basic Will, target's choice) to enemies in the area. Aslynn avoids targeting the nightmares with the blast.
