An deflection bonus is a type of modifier available for a creature's armor class, representing a barrier that deflects incoming attacks before they strike the creature. (Thus this type of bonus is effective against touch attacks.) This bonus is used as a catch-all for bonuses that do not cleanly fit the other types of armor class bonuses; it can be obtained as an item property on several types of items (gloves, ring, belt, helmet, cloak, or weapon), and as a result of several spells (aura versus alignment, mage armor, magic circle against alignment, protection from alignment, shield, shield of faith, and undeath's eternal foe). Multiple deflection bonuses do not stack.
