Ran again after the update. Dialogues helped. The entry room where you politely wait for the cultists to finish their discussion is a little jarring - it takes forever for them to notice the PC / Gnommon and become killable.
The map is nice, although the thick white lines seemed a little over-done.
I was doing in on normal with a lev 20 toon with decent gear - I can't comment on the fights or the difficulty. If the cultist HP had gone up, I didn't notice.
The treasure bags dropped by the skeletons are still not susceptible to pickup, but the skeletons seemed to be harmed by positive energy (I think - I was trying to hit one with a scroll before my summons and my hireling killed them all). Thanks for that if true.
All in all, a good fun quest. Considering the difficulty the XP felt about right. Considering the time the quest takes, well the zergers will be looking elsewhere anyway.
