So I did a bunch of play testing and since the last bug I saw, everything is pretty darned stable. So I thought I'd dabble into the codebase. Two things that I've always thought were missing are Barbarians and Monks. When it comes to new classes there's quite a bit of work to do, but here's a brief summary of the changes it took:
Add to class enum
Increase NUM_CLASSES
Update all references when loading characters for class base enhancements (starting weapons, magik type, combat/movement bonuses)
Place weapon and armor restrictions
Set stats
Set leveling names
These were pretty straight forward. The harder portion is updating the .RES files. The character descriptions and images are pulled from PICS.RES inside the UI/CREATEC folder. Slade is not very stable when viewing this and can't save changes to res files. XWE will save but it messes with the dirrectory structure, doesn't place any new files in the right content chunks, and otherwise kills off the .RES.
SO! I've started extracting the need for the description texts and images from the actual resource file. This required moving some of the STATS.H definitions to a new header file and changing up StatsUpdateCreateCharacterUI s little. But what it provides is an easier way to insert the new content. I don't think it will be adapted for the real branch... but If I start my own branch I'll definitely make it available. It will have a bare structure looking directly for the files instead of navigating the .res sources... and should make adding new classes much easier for anyone who wants to.
I've got some issues to work out, but once they are done I'll try to post the code changes.

Barbarian:
Str 40
Con 40
Acc 10
Spd 35
Mag 10
Stl 10
Weapons: Axes and Maces (and staff because there is no built in restrictions on the weapon type)
Armor: Leather
Magic: Mage
Starts only with runes for leap and speed buff spells. Only starts with these spells.
Class advantages:
+25% jump
+25% attack speed
+25% damage
+20% health regen
I think it all makes up for the weapon/armor limitation
