Ok im starting a pathfinder Campaign with the alternate rule for armor as damage reduction just wondering what changes to damage reduction and what stays defense? for example a shields ac goes into defense but an armors ac goes into damage reduction aswell as natrual armor and can be bypassed by magic. but what about things that dont list a specific type of ac bonus like mage armor gives you +4 bonus to armor class does that go to defense or damage reduction? sources would be much appreciated.
