Airborne Slam

You launch yourself 20 feet upwards in a spiralling gust of wind, then come crashing down on a point within range, forcing all creatures within 10 feet of your landing point to make a Strength saving throw or take 6d6 bludgeoning damage and be knocked prone, or take half as much damage and stay standing on a successful save. You suffer no damage from the fall.

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