Social Merit
Child (1-3) (M3): Your supernatural abilities manifested early. The depth of this flaw depends on just how young you are and on the situations you are likely to be in (if you're eight years old and your cabal hangs out in a bar, you have to figure out have to get in). Quite likely, you also have the Short flaw.
Good Old Boy/Girl (2) (K:UH): You're just a nice person, and people recognize and appreciate that. +1 die on social rolls when interacting with your fellow folk.
Innocent (2) (CL): You have an aura of childlike innocence (whether you really are or not). -2 difficulty on rolls involving Subterfuge or Manipulation.
Pitiable (1) (VPG2): You have an aura of child-like-ness/innocence about you, and many have the urge to pity and protect you (unless they're of a Nature that doesn't allow them that sort of thing). This can be helpful, but it may also be annoying.
Social Flaws
Airhead (1) (K:UH): Maybe you have trouble paying attention, maybe you're just clueless, maybe you just look like a flake; no matter what, people don't take you seriously. Modify social rolls as is appropriate.
Craven Image (1) (CL): There's something about you that makes you appear sniveling and "low." In appropriate situations, social difficulties are at +2.
Disturbing Mannerism (2) (CL): You have a habit or character trait which is peculiar, gross, or annoying. You may not even be aware of it-but boy, everyone else is. Difficulties of social rolls are increased at the ST's discretion.
Enemy (1-5) (most): Somebody's out to hurt you or your reputation, or even kill you (or people close to you). A 1-point enemy is less than or comparable to your own ability, a 5-point enemy could easily kick your ass into next Tuesday.
Isolated Upbringing (1) (S): You were raised in your supernatural society, or were somehow otherwise sequestered away from "normal" life, so you have trouble dealing with this Outside-World thing. Dealing with any community outside the one in which you were raised adds 1 to social difficulties, or reduces your Social pool by one.
Mistaken Identity (1) (VPG2): People think you're someone you're not; even if that person isn't bad, it can still cause you trouble if they realize you're not who they think you are.
Mistreated Minority (1 or more) (S2): You belong to a group or have a trait to which the average person will react badly. This depends a lot on where the game takes place and what kind of people you run into, so check with the ST before you assume you can take this. Yes, if you're playing an openly gay man in a backwoods redneck area, that may cause you problems. If you're playing an openly gay man in a game focused on the New York art scene, that probably won't be a problem.
