Shattered Kingdoms

Is there a list anywhere that tells what the skills of each class are?

Afraid not. If you really want to know about class XXX, spend a minute to create one. As soon as you choose your class, you can see the list.

Yeah, there is, but it's a bit outdated. Supamang is the name of the dude who had an old website. I suggest taking 15min and making your own pages with mushclient or another client that can convert to html tables.
