Pole Trip [General]
By thrusting the end of your weapon through the legs of an opponent and twisting sharply, you can knock your opponent to the ground.
Prerequisite: Weapon Focus (glaive, longspear, quarterstaff, ranseur or spear)
Benefit: You are able to make trip attacks with a quarterstaff or pole arm you have applied the Weapon Focus feat to. If you are tripped during your own trip attempt, you can drop your weapon to avoid being tripped.
Special: A fighter may select Pole Trip as one of his fighter bonus feats.
