bloodbath

A sphere of negative energy ripples out in a 30-foot-radius sphere from yourself. Each creature of your choice in that area must make a Constitution saving throw, as blood begins seeping out of every orrifice. A target takes 12d6 necrotic damage and is blinded and deafened for a minute on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the damage increases by 2d6 for each slot level above 6th.
