Air Cannon

You extend your arm out towards the target. a blast of air flows out of your arm and towards a target within range. make a ranged attack roll against the target. on a hit, the target takes 1d10 bludgeoning and must succeed on a Strength saving throw. if the target fails the saving throw,  the target is pushed 5ft away. 

 This spells damage increase by 1d10 whe you reach 5th level (2d10), 11th level (3d10), and 17th level (4d10).
