Regarding Knowledge Checks

[Viking Bastard]

So, ask a cleric about some basic fact relating to his god or religion in general he's probably going to just know it. If you want to know some obscure fact about some ancient cult, ask the expert, who may well not be the cleric.

Sure, which is why I still use INT + Religion for trivia knowledge like that, but WIS + Religion for Divination and Detect [Divine] Magic effects.
