Ancestors' Voice

The otherworldly voices of the denizens from Beyond the Veil echo through you.
Each creature in a 15ft cone must make a Wisdom saving throw. A creature takes 3d8 force damage on a failed save, or half as much damage on a successful one. If this amount is greater than the creature’s Constitution score it is also stunned for 1 round. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd.
