C. 820 yes, too many to name really.

Here's a thread full of ones I personally enjoy the look of http://www.giantitp.com/forums/showthread.php?t=165439 and there's a few more recent classes you can find them all here http://www.giantitp.com/forums/showthread.php?t=240717.

Oslecamo continued his thing on another site and made all advanced versions of creatures into Prestige Classes.
It's also subject to more of that, balance checking, thing people like to do to make sure something isn't too powerful.


Thread has same name on both sites.
