The problem is a bit more than just having low App, but that V20 Appearance rules dont work cross splat anyway.I don't know the nuts and bolts of Exalted character creation, but if the low Appearance attribute is going to cause this much of an issue, is there anything that we could reasonably switch around on the character sheet if @DragonParadox was willing to let us do a bit of retconning? If we're ever going to do it, it would be better to do it now, while we're only a few days into the quest timeline.
Cappadocian, Samedi and Nosferatu disfigurement flaws also lower App. I have no idea why that makes you less scary.
