Greater Bane Weapon

At 12th level, an inquisitor can imbue one of her weapons with the greater bane weapon special ability as a swift action. A greater bane weapon excels against certain foes. Against a designated foe, the weapon's enhancement bonus is +2 better than its actual bonus. It also deals an extra 4d6 points of damage against such foes. This ability only functions while the inquisitor wields the weapon. If dropped or taken, the weapon resumes granting this ability if it is returned to the inquisitor before the duration expires. This ability lasts for a number of rounds per day equal to the inquisitor's level. These rounds do not need to be consecutive.
