I found the Dietmar fight to be rather a steamroll. I regard the fight outside the cave and the Evelyn fight as difficult. I actually raised the difficulty to hard after the Dietmar fight, and then beat Evely in third try. Losing my main to things that explode in the first tries, I still dont get that. But managed to only lose my cleric henchie last time while staying away from thins that explode. Which then decided not to explode actually, don't know why.

I am making progress now on hard, using potions and scrolls and crafting and spending my money on skills. I'll lower the setting if it gets too hard.

I have a twohanded knight (main). A ranger/rogue, a fire/geo wizard and a shield fighter turned Cleric.
