Patch 7.1 is the first major content patch for the Legion expansion, released on October 25, 2016. It added a new level 110 Karazhan dungeon containing 9 bosses, which is only available on Mythic and Mythic+ difficulties. An attunement questline to unlock the dungeon is available in which the player must complete Halls of Valor, Black Rook Hold, Vault of the Wardens, and Assault on Violet Hold on Mythic difficulty. The patch also added the Trial of Valor raid, containing 3 bosses: Odyn, Guarm, and Helya, though the raid will not unlock until November 8. A new max level questline is also available in Stormheim to serve as a lead up to the raid. Additionally, a nine week long questing campaign is available in Suramar. New world quests have been added throughout the Broken Isles.
