You summon a storm of radiant energy bolts that rain down in a 30-foot-radius area. Each creature in the area must make a Dexterity saving throw, taking 12d6 radiant damage on a failed save or half as much on a successful one. The bolts crackle and leave behind shimmering sparks for 1 minute, creating difficult terrain.
