Background: In my game the players are up against a bunch of "Sith" - not really Sith though, but a group of Force users intent on rebuilding the ancient Sith Empire. They have a houserule skill:
Sorcery (Willpower) :
Sorcery is to Lore what Streetwise is to Underworld, if you get my meaning. It's like Mechanics, but specifically mystical, and is used in-game to perform certain "rituals" with various effects (think Nightsisters/Witches of Dathomir, or when Sidious and Dooku were trying to mess with Yoda's mind).
For certain types of Force users, Sorcery is very important. While these are predominantly Dark Side Force users, I don't believe it must be that way. I think the Witches of Dathomir may be an example here.
I'd like to know what people think of this, how it might be used, and what it's limits are. The game rules for Mechanics tend to be more about modding than actual creating and inventing, due to the narrative nature of the game. I think that Sorcery will follow a similar "narrative bent", but like having rolls for things so that I know whether the players are in time to prevent the evil nasty thing from happening, or just a bit late, as is so often the case.
