Death's Breath

You flood a 10-foot radius sphere with negative energy. All creatures in the area must make a Constitution saving throw. A target takes 5d6 necrotic damage on a failed save, or half as much damage on a successful one. 

A corpse in the area of this spell when it is cast becomes invested with a malevolent spark of unlife and lashes out at a creature within 5 feet of it. Make a melee spell attack. On a hit, the target takes bludgeoning damage equal to 1d6 + your spellcasting ability modifier.
