Distort Gravity (HB)

The spell manipulates the direction of gravity on a surface you touch, causing it to attract creatures and objects that are within 15 feet perpendicular to it as if it were the ground. The surface must be at least 10-foot square, and can be up to a 60-foot square in area and can wrap around a corners or 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 spell is cast, a creature can make a Dexterity saving throw to grab onto a fixed object it can reach, thus avoiding a fall.
Where multiple surfaces affected by this spell are in range, creatures and objects are attracted by the nearest affected surface.
When the duration ends, all creatures and objects fall from the surface.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the area that can be affected becomes 120ft square. When cast at 7th level or higher, the duration increases to 8 hours. When you cast it at 8th level or higher, you can affect any surfaces of your choice within 500 ft of you when you cast the spell (each surface must still be a minimum of 10-foot square). When cast at 9th level, the duration increases to 24 hours, doesn't require concentration, and if you cast it every day in the same location for a week it becomes permanent.
