You know, I've always liked Malfeas, and I think that Charm is going to make me finally buy MoEP: Infernals.
I'm thinking of making a gentleman thief. When he failed at doing something awesome, there were no Fiend Caste or Scourge Caste exaltations available. Just a Slayer Caste exaltation. He now uses YOU GO BLIND! for stealth and ETIQUETTE IS DOING WHAT I SAY! to pull off genteel but extremely loud heists, which he gets away with mainly because everyone's too scared and/or charmed and/or stabbed in the voicebox to turn him in. Ebon Dragon as Favored Yozi, of course.
Also, make more of those. Make one for every canon Yozi, even Elloge. Especially Elloge!
The name could be a bit shorter and less obvious. Perceived-Identity-Demanding Ululation? Or just Perceived Identity Demand?
