Bethanization

You bleat an agonizing remark in the tone of voice similar to that of some girl named Bethany at a creature you can see within range. If the target can hear you, it must succeed on a Wisdom saving throw or take 6d6 psychic damage, or half as much on a successful Wisdom saving throw. If the target is Bethany, the spell has no effect.

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.
