Deluge

You transmute the water from the air into a huge bubble of hovering water at a point that you can see within range, dropping it on your enemies. Each creature in a 10-foot radius cylinder beneath the bubble must succeed on a Strength saving throw. On a failure, target creatures take 4d6 bludgeoning damage and fall Prone. On a success, the target takes only half damage. A creature of huge size or larger automatically succeeds on the saving throw against this spell.

At Higher Levels. When you cast this spell using a spell slot of 3rd-level or higher, the damage dealt increases by 1d6 per spell slot level expended above 2nd.
