Death's Breath

A flood of necrotic smoke erupts from a point of your choice within range. Each creature in a 10-foot-radius sphere centred on that point must make a Constitution saving throw. A creature takes 3d6 necrotic damage on a failed save, or half as much damage on a successful one.

Any corpse that is within the area of the spell when it is cast becomes invested with a malevolent spark of unlife and lashes at a living creature within 5 feet of it. If there are multiple living creatures within 5 feet, select a target at random. These attacks are considered melee spell attacks. On a hit, the target takes bludgeoning damage equal to 1d6 + your spellcasting ability modifier.

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