Patch 7.2 is the second major content patch for the Legion expansion, set to release on March 28, 2017. The Broken Shore will become an endgame zone in the patch, with players advancing up the island until they reach the Tomb of Sargeras. The Tomb of Sargeras will be available as a 9-boss raid, with bosses including the Avatar of Sargeras and Kil'jaeden. A new 4-boss dungeon called the Cathedral of Eternal Night will be available at the top of the tomb on Heroic, Mythic, and Mythic+ difficulties. Additionally, Return to Karazhan is being split into two dungeons: Upper Karazhan and Lower Karazhan, and will be available on Heroic and Mythic+ difficulties now. The Arcway and Court of Stars will also be available on Heroic difficulty. The difficulty of Heroic, Mythic, and Mythic+ dungeons will also be increased. The patch will also add flying in the Broken Isles, with a class-specific flying mount for each class. The Burning Legion will periodically assault areas in the Broken Isles as well.
