Everything

In your chosen field, your name is mud. Perhaps you’re a scientist whose bizarre theories have cost him the respect of his peers… or an academic who wound up on the wrong side of departmental politics… or a journalist who stepped too far over the line of credibility. Whatever it is you did (or are reputed to have done), your professional associates look down on you. Add +2 to the difficulty of your social and Background-based rolls when you’re trying to get those associates to take you seriously. Although this is a common Flaw among the feud-happy Etherites, anyone who depends upon a professional reputation can be discredited in this fashion – professorial Hermetics, corporate-ladder Syndicate ops, White Tower agents, and other competitive-field mages can fall afoul of a bad rep too.
