Water Lash

You instantaneously cause a 5-foot cube of water that you can see within range to take a shape of your choice and strike one creature you can see within 5 feet of that water. The target must make a Strength saving throw. On a failed save, the target takes 4d6 bludgeoning damage, and if the target is Large or smaller, you can push it up to 15 feet in a straight line or knock it prone. On a successful save, the target takes half as much damage and isn’t pushed or knocked prone.

Until the spell ends, you can shape the same cube of water or a different one and make another strike as an action on each of your turns.
