Choose a point within range. All creatures and loose objects of your choice that you can see within a 20 foot radius of that point rise vertically, up to 20 feet, and remain suspended there for the duration. The spell can levitate creatures and objects that weigh up to 500 pounds. An unwilling creature that succeeds on a Constitution saving throw is unaffected. 

A creature in the area can move only by pushing or pulling against a fixed object or surface within reach (such as a wall or a ceiling), which allows it to move as if it were climbing. You can change the target's altitude by up to 20 feet in either direction on your turn. If you are in the area as the spell is cast, you can move up or down as part of your move.

When the spell ends, all creatures and objects in the area float gently to the ground if they are still aloft.
