Defensive Weapon Training (Ex)

Source Weapon Master's Handbook pg. 18
The fighter gains a +1 shield bonus to his Armor Class. The fighter adds half his weapon’s enhancement bonus (if any) to this shield bonus. When his weapon training bonus for weapons from the associated fighter weapon group reaches +4, this shield bonus increases to +2. This shield bonus is lost if the fighter is immobilized or helpless.
