The creature can attack on the wing with increased mobility.
Prerequisite: Fly speed, Dodge, Flyby Attack, Mobility.
Benefit: If the standard action taken by a creature during a round in which it uses Flyby Attack is a melee attack, the creature provokes no attacks of opportunity from moving out of squares threatened by its target.
Normal: Without this feat, a creature making an attack as part of a Flyby Attack maneuver provokes attacks of opportunity as normal from moving out of squares threatened by its target.
