Cry of the Banshee

You open your mouth and a blood freezing scream cries forth causing a wave of necrotic energy to emanate from you. Each creature in a 25-foot cone must succeed on a Wisdom saving throw or take 8D6 necrotic damage.

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, the damage increases by 2D6 for each slot level above 3rd.
