As for the number, I don't know, maybe three? Four possibly? I was thinking since there are unholy things around, perhaps a setting that can shoot holy water. It would be far easier to have a gun with multiple such settings than carrying, say, a bunch of things in one's pockets. In the heat of the moment, you might pull out the wrong thing. You are quite right, I do think I can make something that can cover the main few evils we encounter here. That is what I'm thinking anyway. We will see if the prototype actually is functional.
