Pole Balance

 
Prerequisite(s): None.
 
Benefit: When wielding a pole arm two-handed you gain a +4 circumstance bonus to resist being bull rushed or tripped, and on any Balance checks to avoid losing your footing. You may not use this feat if you are flat-footed or if you are in a precarious position {such as on a tightrope or while climbing) that does not provide you a solid surface against which to prop the weapon.
 
Special: A fighter may select Pole Balance as one of his fighter bonus feats.
