playing the devil's advocate here: Sometimes on quests Will saves are seen as aversion to things that will possess your mind (For an example: On the Evilness and Greed quest a mindsave was rolled to remember well..the events of the quest basically). Another example would be some sort of object or entity attaching themselves to the character (which has also happened many times on quests: Stating a few: Pandemonial Horses, and the Dagger and the Rose). I don't see how having a faith in a god would detour these things, or, now that I think about it , the effects of spells requiring a will save unless AFTER the spell (Say, dominate person) was cast, the person was then told to do something against the deity.
This seems more of a case by case basis rather than a straight + to will save, and I think there could be better ways to incorperate it into Rp if some thought was put into it.
on the other side of this: I dont pretend to know how anything in PnP, D&D or NWN works , so Im just answering this to what I think, in accordance to strict rp, unattached from dice or pnp rules or anything of that sort.
