I have a question about the spell "Beast Shape I". Do you acquire the natural armor of the creature polymorphed into? So, for example, if you cast Beast Shape I and changed into a small crocodile would your natural armor be +4 for the crocodile and then +1 bonus for the spell for a total of +5 to your ac from natural armor?
And what if you had a mage armor spell on you before you polymorphed? Would that bonus also still be active after you polymorphed into the above mentioned crocodile for a total of +9 to your ac?
Thank you in advance for your help.
