Mythic+ is a 5-man WoW dungeon/instance mode that adds increasing difficulty level from the initial Mythic run based on the activation of a Mythic Keystone from the previous level of difficulty. It is similar to an endlessly increasing Challenge Mode. Each level of Mythic+ Dungeon gives you an end of dungeon chest with Azerite Power to boost your Heart of Azeroth (depending on Mythic+ level completed) and 1 random epic peace of gear for your character.
You can entrust us to farm reputation to a new Battle for Azeroth factions, which is necessary to unlock new dungeons, ability to fly and other features. For example, revered reputation with all Battle for Azeroth Factions granting you tons of toys, pets, profession recipes, gear and other rewards - it's worth it!
