I can add a custom title.
I don't see much wiggle room with a paladin oath that says "don't lie or cheat" and yet people seem to think that them using the deception skill is fine.I simply don't see the wiggle room other people read into it. They "will not" wear metal armor. Seems pretty darn clear to me.
This is getting repetitive: if you don't like the rule ignore it when you're DM.
