Aqua Burst

 You conjure forth a rapid burst of water that crashes down on one creature you can see within range. The target must make a Strength saving throw. On a failed save, the target takes 1d6 bludgeoning damage and is pushed 5 feet in a direction of your choice. If the target is submerged in water, the damage increases to 1d10 instead.

Cantrip Upgrade. The damage increases by one die, and the push distance increases by 5 feet when you reach levels 5 (2d6 or 2d10 and 10 feet), 11 (3d6 or 3d10 and 15 feet), and 17 (4d6 or 4d10 and 20 feet).
