Aerokinetic Platforms

You can start playing music of any kind to transmute the air beneath your feet to a solid surface, allowing you to walk on air. Horizontally, you may walk on air at your normal movement rate. You may also walk vertically, as if on stairs. If something hits the platform, the DM may require you to make a performance saving throw to keep the platform from disappearing.

The spell ends if you are knocked prone, fall unconscious, lose your footing, or stop playing music.
