Hello,
I am bad at questing as I could easily fall asleep especially when the grind is boring.
How do you unlock it? Is it by Renown Level or finishing the Main Campaign storyline?
I think it is on the storyline. Need confirmation.
I reached level 80 on dungeons and crafting.
keep questing
Short and to the point.
Also, to add to this, keep doing the thing you wrote about not being good at. Eventually things will pop off.
You have to complete the main storyline for all the zones to unlock adventure mode for the War Within (which is by default unlocked for all your alts).
You don’t have to do side quest content unless you’re wanting Loremaster.
Finish the main campaign. You can do only the quests with the shield around the exclamation mark and ignore the rest.
Also, take a moment to fly around and fully explore each zone while you’re there. Then you’ll get Pathfinder “for free”.
You should really know by now that you should quest at least the first time through for these kind of unlocks. It’s usually fine to skip on alts.
You have to do every quest marked as campaign quest - get the campaign achievement for the campaign quest in each zone. At the end of the azj-kahet levelling campaign you will be sent back to dornogal to talk to moira thaurissian. Once you do world quests and adventure mode are unlocked. The campaign currently stops there.
Thanks for the replies.
I reached level 80 without seeing Azh-Kahet. I dont know how to get there. So i just follow the storyline and it led me there.
I have the Collector’s Edition with its Art Book. I have seen Orweyna, NPC on the last part of the book. Alas, she just started showing up on the storyline. Well, i think i am on the right direction.
I have no play time to do all the quests, just the campaign. But it is still long. Many of them are boring grind like fetch quests. If it involves going to the dungeon, it would keep me awake. Anyway, i have to work. Will continue later at night
I unlocked world quests and events at level 76 by doing the campaign, and so can you.
The next part of the campaign which will start after launch does require level 80.
I am not really into leveling. But i started getting lots of Valor-like stones currency which i cant spend. The game hasnt introduce me to it yet. And i realized i would need to see World Bosses and special events. I have to unlock it somehow.
I spent time more on Dungeons and Crafts. I need those awesome food buffs, elixirs/potions and flasks… i am going to amass them instead of buying them. Yeah, i would sell my extra at high price. That’s how the market plays. 
They shouldn’t require you to do the campaign. The quests are horrible. And they only give 10-11k exp when a lfg dungeon gives 67k. Making us suffer through their crap story telling.
I dont mind the campaign. But somehow, many would want it like this. It’s just too long for me.
I dont want to require dungeons for the campaign. It would be unfair for many Casuals.
Level 80 dungeons seems brutal for ungeared level 78 non-dungeon players unless they are carried. By the time super Casuals without early access reach the real Level 80 dungeons especially the one that requires skyriding/flying, without the elites to carry them, it would be very painful.
just have to complete the campaign quest 
When you press L and it shows the main The War Within thing and then 0/5 chapters. You really wanna pay attention to that. At some point it will say something like, “get to Renown 4 with each clown show to continue the campagin” that’s how you know you’re on the right track.
Oh and it tells you the next quest to pick up to continue it.
100% this.
And, for me (ymmv), despite Streams making claims that “there was a shortage of content”, I hit 80 when I was in the Ringing Deeps!!! That was JUST from the main storyline.
So it doesn’t surprise me at all that someone hit 80 and still hasn’t unlocked Adventure Mode, etc.
Good luck!
I have completed the campaign quests on 2 characters but the world quests for the last zone are not showing up. Any ideas?
I dont think they have have released that yet… for Ahj-Kahet.
Let me know if they did.
You have to pick a “Pact” in the Weaver’s Lair each week. Basically align your account with one of the three main leaders of the Severed Threads. Once you do, world quests for that leader will show up for the week.
