Dead Again

Each humanoid corpse within range explodes with dark energy. Each creature except you within 5 feet of such a corpse must make a Dexterity saving throw. A creature takes 2d6 necrotic damage on a failed save, or half as much on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the radius of each explosion increases to 10 feet. The damage increases by 1d6 for each spell slot above 2nd.
