Corpse Explosion

The corpse of a recently deceased creature rapidly bloats at your command and erupts in a gruesome explosion. When a creature dies within 60 feet of you, you can use your reaction to detonate its body in a gory display of flesh, guts and bone. Each creature within a 10-foot-radius sphere centered on the corpse must make a Dexterity saving throw. A target takes 2d8 necrotic damage on a failed save, or half as much damage on a successful one. The size of the explosion increases by 5 feet for every size larger than medium.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d8 for each slot level above 1st.
