Do you want outlaw appearance? You need to unlock artifact weapon for outlaw and then do few chapters of story line in stormheim. Once you’re done with that you will have to run vault of the wardens and neltharion lair dungeons for two items which drop from last boss in NL and 3rd boss in Vaults. The fastest way to reset the dungeon is to go to your garrison, talk to WoD lfr npc and sign up for any lfr from wod. Once you’re in you have to click on lfr icon and use “teleport out of dungeon”. Do not click leave the dungeon group tho! This way once you’re done with running vaults and item didn’t drop you can click on teleport to dungeon and then teleport out of dungeon and you’ll be back at vaults of the warden entrance. That’s the fastest way to reset dungeons to run them again.
