Air Slash

You create a slash of a supersonic, magically infused wave of air at a creature or object within range. Make a ranged spell attack, on a hit, the target takes 1d6 magical slashing damage and if the target is Large or smaller, it must make a Strength saving throw against your spell save DC or be pushed back 5 feet. 

The spell creates more than one wave of air when you reach higher levels: two waves at 5th level, three waves at 11th level, and four waves at 17th level. You can direct the beams at the same target or at different ones. Make a separate attack roll for each beam. Additional creatures targeted by this spell must also make a strength save against your spell save dc or be pushed back 5 feet, but can not be pushed back more than once with each casting of the spell.
