Anarchy Storm

Create a 40-ft. radius storm of chaotic energy centered on a point within range. Hostile creatures treat the area as difficult terrain. When a hostile creature enters the area for the first time on a turn or starts there, it must make a DEX save, taking 45 (10d8) variable damage on a failed save, or half on success. Roll 1d8 each round to determine the damage type: acid, cold, fire, force, lightning, poison, psychic, or thunder.
