There was an issue regarding temple of demon god, if you party with the Instance Creator any of your other online character will also teleported. This happened since the Instance exist lol.
you get teleported even your current char not even the same party
It warps/recalls you to fire basin map, even without a party randomly.
After testing 17.2 quests , along with the items and cards, I would gladly suggest that we use back +12 Capped CEB (iro Version i think). Tested with even basic gear this will help a lot, without needing +18 tickets. Whoever tested 17.2 item will know how significant future damage will come in woe, later all will be one shot meta again.
Talk to the said npc, it will give the quest to kill Demon God , Brinneranea and Muspelskoll i dunno how to spell these mob. But yeah they give the quest first to you before you can even speak with Nidhogg.
