Keep in mind that this is nowhere near all thats needed. After you do the stuff Faefu listed you get the Detective title which you need to equip to start the actual questline.
As of now, the questline hasnt been solved completely.
Edit: you can get the Inert Peculiar key without having the detective title.
As i just edited my post, you can go get the Inert Peculiar key right away, it doesnt require the title. That will save you a little bit of work and confusion at least.
I mean, the dev that designed this is literally in the discord made for finding stuff like this.
Sure blues shouldnt release a guide, but saying its there wouldnt hurt.
I think only getting the Title part will be off. I think the rest will stay for longer. Still I think with how it’s going we will have full guide before Christmas, so there will be plenty of time for anyone how checks wowhead or mmo-champion to do it.
Lastly I think people need to learn not stress too much about fomo. If you miss out then you miss out, it’s not a big deal.
