Baleful Howl

You let loose a thunderous howl that shatters both the flesh and the convictions of those nearby. Each creature in a 20-foot-radius sphere centered on you must make a Strength saving throw. On a failed save, a creature takes 5d8 thunder damage and is frightened for 1 minute. On a successful save, the creature takes half as much damage and isn’t frightened.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d6 for each slot level above 4th.
