Crescent Blade Dervish (Combat)

In the thick of battle, your crescent blades spin in arcs of glittering death, striking faster than the eye can follow.

Prerequisites: Dex 13, Int 13, Combat Expertise, Exotic Weapon Proficiency (crescent blade), base attack bonus +2.

Benefit: When you wield a crescent blade and you threaten three or more opponents, you gain one additional attack at your highest base attack bonus.

Special: You can use Crescent Blade Dervish in conjunction with the Whirlwind Attack feat. In such a case, you can attack every foe you threaten, plus an additional foe of your choosing a second time.
