Diving Charge( Races of the Wild, p. 150)
You can dive down at a target to deal a devastating strike.
When charging while fl ying, if you move at least 30 feet and descend at least 10 feet, you gain a bonus on your damage roll based on your fl y speed. (The damage bonus is based on your fl y speed, not how far you have moved in your charge). Fly Speed --------- Damage Bonus. 30 feet or slower -- +1d6. 31 to 90 feet -------- +2d6. 91 feet or faster ---- +3d6. In addition, after you make this attack you can choose, regardless of your maneuverability, to turn in place so that you are now fl ying parallel to the ground.
