Corpse Explosion

Scan the battlefield and any corpse within 60 feet of you that you can see the torso of is an eligible target. You weave your signs as stare at the corpse willing it to burst. Each creature in a 15-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 6d6 Necrotic damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
