Aqueous Blast

You shoot out a rapid stream of water from your palm. Make a ranged spell attack against the target. On a hit, the target takes 1d6 bludgeoning damage. You can choose for either you or the target creature to be pushed back 10 feet. 

This spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6). At 11th level you can increase the distance either you or the target creature get pushed back by to 20 feet.
