15 Best New Features in World of Warcraft: Legion

Mythic+

After the Emerald Nightmare raid arrives, dungeons will receive the new Mythic+ difficulty. This is a new scaleable difficulty that works somewhat like Diablo 3’s Greater Rifts. You use a keystone to access Mythic+ and if you complete a run within the time allotted, an opportunity to upgrade the keystone is offered. As you use higher levels of keystones, enemies will become difficult and keystones from level three onwards will have different modifiers – like more trash mobs, higher boss health and even volcanic eruptions – to further spice things up.
