Epic Level Handbook
You can strike at nearby opponents in a blindingly fast spinning assault and follow it up with extra attacks.
Prerequisite: Dex 13, Int 13, Combat Expertise, Dodge, Mobility, Spring Attack, Whirlwind Attack, base attack bonus +4.
Benefit: As part of a whirlwind attack full-attack action, you can make all of your additional attacks based on your base attack bonus in addition to your normal attacks granted by the feat. For example, a 12th-level fighter with Improved Whirlwind Attack can make all his normal Whirlwind Attacks (each at +12 plus Strength and other modifiers) and then make the two additional attacks he gains from having a high base attack bonus (at +7 and +2 plus Strength and other modifiers). He does not get to make these additional attacks against every opponent; he only gets the two attacks at the end of his whirlwind.
Special: A fighter may select Improved Whirlwind Attack as one of his fighter bonus feats.
