Boarding Assault

You launch yourself and up to 3 allies within 5 feet of you 30 feet upwards in a spiraling 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 and your allies suffer no damage from the fall as long as you hit at least one hostile creature.

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.
