Holding your polearm further up its length, you can strike adjacent foes as well as those further away.
Prerequisites
Base attack bonus +5.
Benefit
You can choose to take a –2 penalty to your AC to gain the ability to threaten all opponents within the reach of your reach weapon, rather than those you would normally threaten with your weapon. You must choose to use this feat before making an attack roll during your turn, and its effects last until the start of your next turn.
