Ah, Pilgrims, the quest which everyone diedd for the infamous (now nerfed) bonebreaker sword. I personally like that we still have quests with certified kill rooms. However, it could use better items in reflection of the new server setting.
Personally I found pilgrims very simple if you brought a cleric with Turn Undead, or a Paladin with bless weapon. It was the sort of quest you had to gear up to accomplishing, by getting negative resist items, +2 vs outsider items, and such. A newly assembled team without any of those is going to have to be very careful or they'll have a bad time. As long as your character didn't have a janky build, you'd do fine at 10+
