Levitate

One creature or object of your choice that you can see within range rises vertically, up to 20 feet, and remains suspended there for the duration. The spell can levitate a target that weighs up to 500 pounds. An unwilling creature that succeeds on a constitution saving throw is unaffected. The target 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 the target, you can move up or down as part of your move. Otherwise, you can use your action to move the target, which must remain within the spell's range. When the spell ends, the target floats gently to the ground if it is still aloft.

Levitate allows the caster to move himself or herself, another creature, or an object up and down as desired. A creature must be willing to be levitated, and an object must be unattended or possessed by a willing creature. The caster can mentally direct the recipient to move up or down as much as 20 feet each round, by concentration. The caster cannot move the recipient horizontally, but the recipient could clamber along the face of a cliff, for example, or push against a ceiling to move laterally (generally at half its normal land speed).

A levitating creature that attacks with a weapon finds itself increasingly unstable; the first attack has a –1 attack penalty, the second –2, and so on, to a maximum penalty of –5. A full round spent stabilizing allows the creature to begin again at –1.
