If there's one reason people play Mythic+ dungeons in World of Warcraft, it's for the awesome loot you get at the end.
What you NEED to know about Mythic Dungeons in World of Warcraft
Mythic+ dungeons are one of the best ways to quickly gear up your character in WoW, as there is no limit to how many you can run per week, unlike base-level Mythic dungeons. Parties are guaranteed at least two pieces of gear at the end of each Mythic+ dungeon, with the personal loot system determining who gets gear. Loot recipients are random for each run.
In addition to the gear you can only get from running dungeons, you also have the chance to pick a piece of powerful gear from your Great Vault each week. The Great Vault gives rewards based on the highest level keystone dungeons you complete each week, up to a maximum of keystone level 20.
In Season Four of Dragonflight, gear found in caches at the end of Mythic+ dungeons can scale up to item level 509, while loot from the Great Vault maxes out at item level 522. There's plenty of loot to be had everywhere, so here's what the Mythic+ loot table looks like in Season Three of Dragonflight.
