It is one of those things with class balance probably. If the character has issues with the mobs it is because he is a healer and primarily not a quick kill character like tha assassin or barb. You may need to invest in top notch blue protection from Trader and get a good dmg weapon for the BS to do it fast and quick. I had the same issue with my BS on other quests, though I may do this to see later with my BS as he is all blue geared and let you know.
I couldn't survive the first mob attacks before I upgraded my weapon, so that has helped. Even my sixty-something level Guardian struggled. And she's all melee. Just relentless mobs with multiple beatings at once.. Would like a few more individual or paired matchups.
Regardless, a werewolf story line is neat.
