Notes on Natural Armor
Natural armor appears to have significantly changed. It is no longer applied in addition to armor, but in place of. A creature with Natural Armor has a base AC that they add their Dexterity Bonus to. Creatures with Natural Armor use shields normally. If a creature with Natural Armor wears Armor only the higher value is used. Creatures are always proficient with their Natural Armor, and count as unencumbered. Natural Armor never causes disadvantage to stealth even should at Armor Classes over 15.
Creatures with Natural Armor count as armored for the purposes of the Mage Armor spell(I think).
