Benefit
When fighting with the weapon that you choose for this feat, you gain a number of additional advantages. You gain a +4 bonus on all checks made to resist being disarmed. You can wield your weapon against a foe who grapples you without penalty and without fi rst making a grapple check. In this situation, you can take a standard action or a full attack action as normal. When you take a full attack action, you can apply a +5 bonus to any single attack after your fi rst strike. Once per round before making an attack roll, you can instead choose to treat your d20 result as a 10. You gain a +1 bonus to AC.
Special
You can choose this feat only once, for a single specific kind of weapon. The dedication and focus it requires makes it impossible to gain this feat for more than one weapon.
