I don't really know what the stats meant, but in the end I managed to convince the alchimera to take care of the sewers and the town celebrated me as hero! Neat! :)
Thanks for your feedback :) I have to admit, that I had to cut down a lot of what the stats would have meant and in the story line you chose, they play (almost?) no role. If I ever touch the game again, I make them either invisible or make them matter in in a more recognizable way.
