Tidal Crescendo

You conduct an orchestra of crashing waves.

Choose a point within range. A 30-foot-radius tidal explosion erupts.

Creatures in the area make a Dexterity saving throw.

On a failure: they take 8d8 bludgeoning damage and are knocked prone and pushed 30 feet to the edge. On a success the take only half damage and are not knocked prone or pushed away.

Anyone in the 30 foot radius suffers from the Deafened condition until the beginning of the next round as the thundering sound of waves comes pummeling down.
