Air bullet

Through the motions of your hands you weave together a ball of air circling around in your hand. You then shoot it towards a target within 60 feet. The target must make a dexterity saving throw taking 1d8 bludgeoning damage on a failed save, and if the target is large or smaller. It gets pushed 10 feet in a straight line away from you.

The damage increases by 1d8 at level 5, 11 and 17.
