You propel yourself up to 15 feet into the air without provoking opportunity attacks. Then, you briefly gather energy before smashing down onto an unoccupied space on the ground within 30 feet, causing an echoing shock wave. Each creature within 10 feet of you when you land must make a Constitution saving throw. On a failed save, a creature takes 1d12 bludgeoning damage and 1d12 thunder damage, and is also pushed back 20 feet away from you. On a successful save, the creature takes half as much damage and isn’t pushed.   You take no fall damage when you land with this spell. In addition, unsecured objects that are completely within the area of effect are automatically pushed 20 feet away from you by the spell’s effect, and the spell emits a thunderous boom audible out to 300 feet.
