I’m trying to start the questline for the legendary cloak and I’ve read online it’s meant to auto-pop on screen when I have met the criteria. I think I’ve done everything I need to; complete the war campaign, unlock nazjatar, the heart forge and the essence system but it is still not showing for me.
Has this happened to anyone before? Has anyone got any ideas?
When you unlocked Nazjatar, did you do the quests up to creating a portal back to Draztalor? If so, try going through it from Draz to Naz and back again to see if the quest pops.
From what I read, the war campaign is not required, just 120, Heart Forge and Nazjatar fully opened.
If that does not work, close the game, delete the “Cache” folder in your World of Warcraft\Retail folder and log back in to see if it pops up then.
Yeah I completed the intro quests and unlocked the portal. Just jumped through it for the sake of it and nothing happened.
Deleted the cache file as you suggested, nothing came up when I logged in so I jumped through the portal again and still nothing 
I know this is going to sound really silly, but I have to ask anyway…
Have you checked to see if the quest is already in your log and maybe just isn’t being tracked?
No probs 
Yeah, only quest I have is a Nazjatar bounty I picked up earlier.
Hey Johneldordao! Did you recently do a faction change? This could be preventing it from popping up so if you have, create a ticket and we’ll be able to look into it more for you 
If you haven’t, there’s a whole guide on picking up this quest here https://www.wowhead.com/guides/visions-of-nzoth-introduction-questline-horrific-visions-assaults#unlocking-visions-of-nzoth-content
