Distort Gravity

The spell manipulates the direction of gravity on a non-horizontal surface you touch, causing it to attract creatures and objects within 15 feet of it as if it were the ground. The surface can be up to a 60-foot square in area and can wrap around a structure, if its geometry permits. A creature can walk on this surface as if it were level ground, even if the surface is perpendicular to the ground or upside down. When the duration ends, all creatures and objects fall from the surface.
