Aqueous Blast

You conjure a powerful stream of water from your hands.  Make a melee spell attack.  On a hit, you deal 1d8 bludgeoning damage to the target and you are pushed back 10 feet in a straight line by the pressure of the water.

This spell's damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
