Well I just don't see how you can make any melee attacks. Right now in the goblin mines where those "Night Knights" are, my melee hit chance is 38-55%. Even my summons can't hit for shit, it is as if they fight with their eyes closed.
You have too little points in strength I guess. Strength determines your chance to hit and your damage output for a melee character. And you can buff your chance to hit (e.g. with a "bless" spell).
With 11 points in intelligence you obviously have too little points in strength...
Also leadership is an important skill. Your whole party can gain up to 10% chance to hit with leadership.
