The Old God N’Zoth has been unleashed from his titanwrought prison, and an ancient corruption has taken root across Azeroth, turning friends into foes and trapping warriors’ minds in nightmare visions of a hopeless future. As despair and madness consume the land, the heroes of the Horde and the Alliance will need to fight for their sanity—and the fate of their wounded world in this content update.
The Visions of N’Zoth content update is packed with new features, including two new Allied Races—the fox-like vulpera (Horde) and the crafty mechagnomes (Alliance); the introduction of Assaults and N’Zoth’s Horrific Visions; new Corruption-tainted weapons and gear, a new legendary cloak to craft and upgrade—Ashjra’kamas, Shroud of Resolve; raid that takes you into the heart of the Black Empire— Ny’alotha, the Waking City; and much more.

Battle for Azeroth Season 4
Battle for Azeroth Season 4 begins, January 21 and includes an all-new Affix—Awakened— for Mythic Keystone Dungeons, Heroic Difficulty Darkshore Warfront, and more.
New Affix: Awakened
Season 4 has a new affix—Awakened. While the Awakened affix is active, players will discover obelisks throughout the dungeon, which will pull players through the veil to the shadowy world of Ny’alotha. There, players will confront a powerful servant of N’Zoth which they must defeat or the servant will join forces with the final boss in the instance. Once the lieutenant has been taken down, the party will be returned to their regular reality in the location they’re currently standing in. This will enable some interesting skips that don’t involve the use of Rogues’ Shroud of Concealment or invisibility.
New Brawl: Teeming Islands
This large-scale battle brings together two teams of 10 on an island overflowing with powerful creatures. This Brawl brings an additional challenge to the shores of PvP Island Expeditions by increasing the total amount of players from six to 20 on the biggest Islands (Havenswood and Jorundall).
When the Brawl is active, players can join the fight by opening up Group Finder (default hotkey: i), selecting it from the Player vs. Player tab, and queuing up.
