Benefit

When you use the full attack action, you can give up your regular attacks and instead make one melee attack at your full base attack bonus against each opponent within reach. When you use the Whirlwind Attack feat, you also forfeit any bonus or extra attacks granted by other feats, spells, or abilities (such as the Cleave feat or the haste spell).

Special

A fighter may select Whirlwind Attack as one of his fighter bonus feats.
