Wrong Item Level on Mythic+ Reward from Great Vault
- Why is my Mythic+ loot from the Great Vault so low
- The Mythic+ loot I received from the Great Vault was at a lower item level than it should have been
The item level on Mythic + rewards from the Great Vault depends on the key levels of the dungeons that were completed during the previous week.
The order in which you complete your dungeons does not matter, and completing additional M+ dungeons does not compromise the item levels that you have already earned.
See Wowhead's guide to Mythic+ for an overview of the relevant item levels.
