Although they are in a full document, there are a few Master Classes in the Eberron
and Iron Kingdoms
Conversion Guides (the only ones I translated in English yet). Ozcorn and I have also reworked the Artificer as an Expert Class. As I said, I'm not that fond of new Base Classes ...
Added, there are now 55 fan made classes up, plus variants.
My usual go-to for FC stuff is the Fantasy craft database, I do like this compenduim thread idea though. Any chance of some of the authors of these classes sending them to the database?
Also generally, it would be good to see more activity on the FCDB.
It really doesn't get the use it should, that's partly why I started putting this together.
