Whirlwind
Effect:
You can make a Whirlwind attack as the first action of your turn when you are engaged by two or more enemies.
You take a –4 penalty to your AC and PD until the start of your next turn. Then roll a separate melee attack against each enemy you are engaged with. You deal no miss damage with these attacks.
Adventurer Feat:
You now deal normal miss damage with missed Whirlwind attacks.
Champion Feat:
The penalty to your AC and PD is reduced to –2. In addition, disengage checks you make the same turn as using Whirlwind automatically succeed.
Epic Feat:
You can use Whirlwind anytime during your turn, not just as the first action.
