Rework the faustian bargain traitor item

[Mageziya]

Taking Grifflez points, I suppose the briefcase doesn't really feel like an antagonist item, because the antag tends to lose out while the crew benefits more often than not.

If you're buying souls off of people, then maybe you could get a point counter for every contract signed. You could tend spend these soul points on beneficial traits to become the ultimate demon nerd. Of course now, that's a whole other can of worms that complicates everything in terms of design.
