Whirlwind Attack

A Bug
This is a great feat, but unfortunately it's bugged with weapon attacks (a test with screenshots). This feat works properly for unarmed attacks (such as Monks), dealing 2 to 4 attacks on all enemies in a 360 degree arc around the character. While a very expensive feat for players to attain, players do gain substantial Dodge bonuses from the hefty feat prerequisites. This video shows how a Monk uses the feat.
