Just a brief comment on the Aristocrat: although it may need some polishing, it looks like it's off to a good start, and much better than the standard DMG version. Enough class features to be interesting and believable, without going overboard.

Please note the eighth-level class feature should be spelled "Comeliness," and there are a couple typos in the text.

Also, on Etiquette: the basic idea is great--using one's good breeding to cover for a less refined companion--but I'm a little fuzzy on the exact mechanics. What is "social stigma" in this context, and what does the successful Diplomacy check accomplish in terms of mechanics?
