In Patch 8.3, we finally get a legendary item to upgrade and help us out.
If you liked the Mage Tower in Legion, then World of Warcraft patch 8.3's Horrific Visions is content that is designed to appeal to you -- it's content you can do solo or in a small group (up to five players) and it's designed to start off with ramping difficulty that will eventually force you out until you get better at the encounters and better geared to resist the sanity draining mechanic of the Vision.
Patch 8.3 is coming out today!
I mean, I kind of know what you're doing first -- if you want to do anything else in World of Warcraft's patch 8.3, you'll need to do the introductory questline that unlocks everything else, from the Old God Assaults to the Horrific Visions and including the raid itself, since the raid portal for Ny'alotha will switch between Uldum and the Vale of Eternal Blossoms depending on which zone is under attack by the Old God itself.
On the patch 8.3 PTR, a new item popped up in datamining that could allow players to add a socket to any piece of gear that does not already have any sockets.
Turns out legendary cloaks are kind of Wrathion's thing.
