Will someone explain the maximum AC bonus for armors and weapons? Also the maximum special abilities for the same items? It appears to me that +5 is max AC and +6 on special abilities. Also, do things like glamored, slick, shadow cost any enhancement points from special ability points?
Weapons and Armor can have a total of +10 in bonuses, no more than +5 of which can be enhancement bonuses. Most special abilities have an "equivalent" bonus cost that shows how expensive it will be to upgrade the item.
