Corpse Explosion

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.

The corpse must have died within 7 days of casting this spell for the spell to take effect on that corpse. If a target is hit by multiple corpses, they take an additional 1d6 necrotic damage to a maximum of 6d6. 

At Higher Levels: At spell slots at 3rd or higher, the explosion does an extra 1d6 damage for each spell slot higher than 2nd.
