Choose a point that you can see within range as you raise your hands into the air, letting fine sand slip between your fingers. Every large or smaller creature within a 20 ft radius centered on that point is raised up 30 ft into the air and forcefully slammed back down to the ground. A creature must make a Dexterity saving throw upon impact.

On a failure, the creature suffers 3d8 points of bludgeoning damage and is knocked prone. On a success the creature takes half as much damage and is not knocked prone. If the creature impacted a ceiling due to this effect, the saving throw is made at disadvantage. In addition, unsecured objects that are completely within the area of effect are also raised and slammed.
