Initiation Time: 1 action
Range: Self (15-foot cube)
Duration: Instantaneous
A wave of forceful air billows out from you. Each creature in a 15-foot cube originating from you must make a Strength saving throw. On a failed save, a creature takes 4d4 thunder damage and is pushed 10 feet away from you. On a successful save, a creature takes half as much damage and isn't pushed.
In addition, unsecured objects that are completely within the area of effect are automatically mushed 10 feet away from you by the form's effect, and the form emits a thunderous boom audible out to 300 feet.
At Higher Levels. When you initiate this form at a higher level, the damage increases by 2d4 for each level above 1st.
