Aquabolt

You conjure a turbulent sphere of water and launch it at your foes. Make a ranged spell attack on a creature within range. On a hit, that creature takes 1d6 bludgeoning damage and, if it size large or smaller, is knocked back 5 feet.

The spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
