Air Slash

You swing your hand in a slashing motion releasing a condensed wide stream of air in a line at a creature or object within range. A stream of air forming a line 80 feet long and 5 feet wide blasts out from you in a direction you choose. Each creature in the line must make a Dexterity saving throw. A creature takes 1d8 slashing damage on a failed save, or half as much damage on a successful one. This spell's damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
