I have a SOA campaign and a TOB campaign at the moment. I'll save my TOB questions for that forum. In SOA my pc is a cavalier. I'm curious how you folk handle certain roleplaying issues with paladins, in particular their view of thieves. I'll give you my opinion, and then hopefully you'll share your's with me.
Poison: A paladin would never allow a party member to use poison. It is not honorable, and a paladin would not stand for it. That means no assasin, or any weapon, including arrows of biting, that use some sort of poison.
Backstabbing: Like poison, it is not honorable warfare and therefore a paladin would never condone it.
Stealing/pickpocketing: Never, never, never!
Traps: See poison and backstabbing. Never, never, never!
Open locks, find/disarm traps: No problem at all.
Tithing: While the game doesn't have any requirement, shouldn't a paladin tithe at least 10% of his money to the churches in the game?
Restriction on magical items: Do any of you limit the number of weapons and other magic items a paladin can own at any given time?
Association with anyone evil: A paladin would never take anyone evil into their party. I have heard some justify taking Viconia because you are saving her from a lawless mob, and then watching over her to make sure she does nothing evil. I disagree. In my opinion a paladin would likely save her, "notify the law of her presence so they could watch her" (hey you can't do it in the game but this is roleplaying), but never take her in. A paladin's reputation is one of his greatest comodities.
So how do you guys/gals deal with the above issues.
