just wondering how you tell what ctrl 1 dose, it dosn't seem to change the characters writen armor class. I can choose between Armor class 1 to 4, but I cant see what effect it has.
Thanks

It only changes the appearance of the character IIRC. So with armor style 1 it would seem (s)he's wearing no armor, style 2 would give the appearance of your char wearing leather, style 3 chainmail and style 4 platemail. Of course, for Magi it's the different styles of robes, and Thieves will only show leather.

So, it doesn't change your actual AC, only the appearance of the armor you're wearing.
