I'm posting this here for your eyes. Tell me if you see anything obviously unfair or breaking in it? Tomorrow I'm running a Ravenloft game and I am keen on using both the Madness Meter and Traits, because I think they both feed well into the concepts of Ravenloft.
So MM works much like it does in Unknown Armies. I've narrowed the Categories to Violence, Supernatural, and Self. When making a check, instead of rolling against the UA Mind stat I've decided to use something I'm calling Stress for now. Inspired by Ben and Nick's article in Uncounted Worlds, Stress is determined by averaging Intelligence and Constitution. Failed notches and hardened notches work the same. Twelve hardened notches or ten notches in one single category means that the character is now a sociopath.
I've narrowed the Traits down to three categories too; Generous/Selfish, Honest/Deceitful, Merciful/Cruel. They work a bit more like Allegiance does, in that they are a point tally system, rather than a point on a scale between 1 and 100. Characters will slowly increase their point totals in the traits through play. To start, characters begin by distributing ten points in the positive traits and five in the negative. This next part is inspired by Uncounted Worlds too, but from Sarah's article. If appropriate in play, the character can call on their trait to augment their roll. If the character is using Fast Talk, for example, they are being completely honest with their information, they can add whatever is in their Honest Trait to their roll. If they have Fast Talk 80% and Traits 10 Honest/Deceitful 12 their effective Fast Talk roll is 90%. Should they tap the Deceitful Trait while using Fast Talk their roll would be 92%.
This holds unless the character has become a sociopath. If they've hardened themselves too much, they lose their connection to humanity and can no longer invoke those traits until they get some mental help.
This will all feed into Dark Powers points, as this is Ravenloft we're talking about. I can go into that a bit more later if there is interest.
