Mythic Weapon Training (Ex)

Select one group of weapons from the list of fighter weapon groups. You gain proficiency with all weapons in this group. If you possess a feat such as Weapon Focusthat requires you to choose a kind of weapon, you can instead apply the effects of that feat to all weapons from that weapon group. When wielding a weapon from that group, add a number equal to your tier to your CMD against disarm and sunder attempts made against that weapon. You can select this ability more than once. Each time you select this ability, it applies to a different weapon group.
