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 subject to move up or down as much as 20 feet each round; doing so is a move-equivalent action. The caster cannot move the recipient horizontally, but the subject could push or pull his or her way provided there is a surface to grasp (generally at half its base
speed).
A levitating creature that attacks with a melee or
ranged weapon finds itself increasingly unstable; the first attack is made with a -1 penalty, the second -2, and so on, up to a maximum penalty of -5. A full round spent stabilizing allows the creature to begin again at -1.
