+2 breastplate armor +2 ring of protection +2 amulet of natural armor +2 heavy steel shield
you get +16 armor and sit at 26 ac without much effort.
also you can have a higher dex even 14 is fine than you can get a ioun stone for +2 dex for 3 ac from dex
like some of the posters are saying if you avoid taking 40 damage its like auto healing once per round or what ever, most things might hit you but not everything otherwise you will be unconscious before its your turn and you won't be able to heal
