Legion-Slaying Strike (3.5e Maneuver)

You become a whirlwind of speed, striking an entire army of foes in mere seconds.

You make a single melee attack against each enemy you threaten at your highest base attack bonus, but you take a -2 penalty on each attack roll. Resolve each attack separately. If an enemy is damaged by your attack, then it is thrown off balance. You and all your allies gain the benefits of flanking whenever you attack that enemy for one round.
