I wanna be Bruce LeeWin a monk of any race with -2 unarmed aptitude. You must be true to the playstyle and actually use unarmed as the vast majority of your damage (you can train backup support in magic or ranged combat, but no weapons and you have to use unarmed for most things). Transmutations are welcome.
This limits your race choices to DE, HE, Mu, Sp, and Ha. HE/Ha are the least crippling in my opinion, although you could try abusing spriggan speed to escape whenever things go bad. Remember though, you have to actually kill most things in melee...Honor code, and all that. Enjoy the -30% hp if you do go spriggan
For the record I've spent a fair amount of time trying to get a spriggan and DE going, and while I had some success (I think I got 1-2 runes with a spriggan), I have yet to complete this challenge myself. DEMo (played as a monk) may be one of the worst starts in the entire game, and I'm even counting mummies here.
