Corpse Explosion

You cause the corpse of a Medium or smaller creature you can see within range to explode. Each creature in a 10-foot radius sphere centered on the corpse must make a Dexterity saving throw. A target takes 4d6 fire damage on a failed save, or half as much damage on a successful one.

The corpse targeted by this spell and everything it is wearing and carrying, except magic items, are reduced to a pile of fine gray dust. That creature can be restored to life only by means of a true resurrection or a wish spell.
