Crushing Force

You alter the direction of gravity in a 10-foot-radius, 20-foot-high cylinder centered on a point you can see within range on the ground. Each creature in the cylinder must make a Dexterity saving throw. A target takes 5d8 bludgeoning damage and is knocked prone on a failed save as it is lifted 20 feet into the air and then slammed back into the earth. A creature that is flying that is in range of the cylinder is also lifted 20 feet in the air (unless it's already there) and slammed into the ground. A creature takes half damage on a successful save and isn't knocked prone.

 

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level about 3rd.
