The target's tail moves and acts more quickly, almost with a mind of its own. When making a full-attack Action, the target may use its tail to make a dirty trick or steal Combat Maneuver as a swift Action. For the purpose of this attack, the target's tail is a natural weapon with a reach of 5 feet. This spell has no effect on creatures lacking a prehensile tail. If the target already has an extra attack from haste or a similar effect, this spell only allows the tail to make dirty trick and steal Combat Maneuvers, but does not grant an extra attack.
