I had problem with this as well, I think I died about 5 times. But then I realised what a mistake I've made. When I get lvl up's I used the skillpoints too much on given them fair to both strenght and constitution. But when I finally started over again and gave all my points to strenght for the death knight and agility for my hero (I was supposed to use the bow, but forgot it <img src="/ubbthreads/images/graemlins/ouch.gif" alt="" /> )I killed him very easy with only using one or two healing potions.
