You create a torrent of wind that circles around your feet, making you levitate. You then target one creature within 30 ft to blow a gust of wind at them, dealing 1d12 force damage and getting pushed back 15 ft. The target makes a strength saving throw (DC 15), the target doesn't get pushed back on a successful save. Every time it comes to your turn the force damage taken reduces by two(1d12 to 1d10 to 1d8 etc.).
