So... if a paladin takes off his armor and shield, will his AC go up?
What, you think the gods are that easy? You prance around for years, going on and on about how much you love your deity, they're the best, your going to the temple right now, everyone will love how swell I look in this armor, isn't it great, those gnoll arrows just bounce right off, armor rules!, ooh look, that armor in the window, it's even better, I'll take this big pile of money I have and buy it, now i'm even cooler, and what was I doing? Let's go fight some ogres, they'll never hurt me in my new armor!
You think a little, "Oh, sorry, I'll take it off. Gimme those powers, sweetie" is enough? Oh, no, your deity's going to be all, "Let's see how
you like being ignored and mistreated." So get used to being smacked around by every minion with an attack bonus, buddy, 'cause you're going to be working that one off for
levels. If you're lucky, maybe the divine one will forgive you after you retrain...
