Wind Rage

Waving your arms in a ceremonial fashion, you summon and condense a twirling ribbon of air and fling it to a point you choose within range and then crashes with a bursting roar into an explosion of Air. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 8d6 force damage on a failed save, or half as much damage on a successful one.

Any creature that fails the Dexterity Save is also pushed 10 feet away from the the center point of the sphere. 

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
