You invoke magical devastation at a point you can see within 500 feet of you. All spells of 8th level or lower in a 60-foot sphere centered on that point end. Creatures in that area must then make a Dexterity saving throw, taking 12d12 force damage on a failed save or half as much damage on a successful one. If this damage reduces a creature to 0 Hit Points, it and everything nonmagical it is wearing and carrying are disintegrated into gray dust. Creatures disintegrated in this way can be revived only by a True Resurrection or a Wish spell.
