Many people have had this problem over a long time now.. Seen some posts talking about this quest a few years back and it is still not fix.. It seems to work for some people and not work for others.. Dont know why..

It dosnt work for me, necromancer PC player here.. I did try to restart the game without any results, I did tp myself to a town and come back, also did abondon the quest and started it back a few times and nothing seems to work for me..

If anyone finds anything please let me know as well.. I also wonder if the quest work for someone if I could team up with them and try to see what happens if we go in the dungeon as a team.. But this would require someone doing the quest, looking if it works for them, not complete the quest, reach to us and then make a party and go in together.. Dont know if anyone would really bother with this tbh..

won't be spending anything in the in-game store 'till they fix this.
