I find that maxing out two categories and putting a few points into a third works best for me. Seems like you can only get 2 categories to 12 and one to around 4 or so. I checked the manual but could find nothing about what the max number of points you could get for a character was.
I am trying to make my LVL20 warrior into a true killing machine and Strength and Swordsmanship of 12 seem to be the best way to go. I sure hate the health penalties that the runes give you for very small attribute point gains....

Any suggestions on if it is possible to get more attribute points and how they should be set up for a Wa/Ra combo?
