🌀 About The Great Vault
The Great Vault is the Shadowlands equivalent of the Mythic+ Weekly Cache on Battle for Azeroth. Vault will work similarly, but it will allow you to receive a reward for completing a Mythic+ dungeon, a Raid, or for participating in PvP. The more content completed the more items will be available to choose. Our best teams are ready to give a hand in completing each type of weekly objectives. Make a choice using respective options, on reset, you will be able to open the Great Vault and select one item from the items that were added to your Vault the previous week.

Remember, this will make getting specific pieces of loot and upgrades significantly easier, although there is certainly still a random factor.
