Airrow

You launch a projectile made of compressed air from your hand. Make a ranged spell attack against the target's AC. On a hit, the target takes 1d4 bludgeoning damage and is pushed 10 feet away. A Huge or larger creature cannot be pushed by this spell.

The spell’s damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
