Programming the +2 to hit modifier is quite easy, but how can we give the "+2D6" to the active weapons to reflect the Bane ability for the inquisitor?
At 5th level, an inquisitor can imbue one of her weapons with the bane weapon special ability as a swift action. She must select one creature type when she uses this ability (and a subtype if the creature type selected is humanoid or outsider). Once selected, the type can be changed as a swift action. 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.
