You know how to defend yourself against a certain class of weaponry.

Prerequisites: Int 13, Base Attack Bonus +5

Benefit: Choose a weapon group from the warrior’s weapon training class ability list (except natural weapons). You gain a +2 dodge bonus on AC when an opponent attacks you using a weapon from that group. If you also have the weapon training class feature in the selected group, your dodge bonus from this feat increases to +3.

Special: You can select this feat more than once. Its effects do not stack. Each time you select this feat, it applies to a different weapon group.
