You create a spinning ring of debris that spins around you rapidly in a 5-foot radius. When you cast this spell, choose whether the disk is rotating clockwise or counter-clockwise. When a creature enters the spell's area for the first time on a turn or starts its turn there, it must succeed on a Strength saving throw. On a failure they take 2d6 bludgeoning damage and are pushed 5 feet in the direction that you chose when you cast this spell. As a bonus action, you may change the direction the disk spins.
At higher levels: When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 2d6 for each slot level above 1st.
