Flyby Attack
(Monster Manual II, page 18, DnD 3.5)
[General, Creature]
A creature with this feat can attack on the wing.
Prerequisite
Fly speed
Benefit
When flying, the creature can take a move action (including a dive) and another standard action at any point during the move. The creature cannot take a second move action during a round when it makes a flyby attack.
Normal
Without this feat, the creature takes a standard action either before or after its move.
