There was an interesting discussion on the ability of a nun to bless water, but I am more interested in the idea of the personal faith (which Gallahan was alluding to) of each individual character.
I believe that this will definitely influence the character's reaction to, and interaction with, the supernatural across the spectrum from good (e.g., angels) to evil (e.g., demons). For example, take Gallahan's example:
That's what makes a crucifix powerful against vampires. It's not the shape or design or cross itself. The crucifix is merely a focus for the true power: FAITH. A person who doesn't believe in God would have no more success wielding a cross (in my opinion) than wielding a tennis racket. I love the line from Fright Night, when the vampire hunter produces a cross to ward off the bad vamp, and the vamp grabs it easily and says: "To use that on me, yah gotta have faith." And later, when the cross does work, we can see the strength, resolve and FAITH in the vampire hunter's face. Great movie, great moments.
I guess my questions are:
1) do any of you explicitly include a PC's personal faith as part of your game(s)?
2) how do you quantify the degree of faith for a PC?
2) how does that faith (or lack thereof) influence game mechanics? For example, rolls to save vs. horror factor and/or insanity, or psychic approaches to exorcism, or even possibly bonuses to strike against supernatural evil.
I would love to hear your thoughts on this issue as I am considering the possibility of making faith more important to the game I am starting.
