Great Vault

Each week the Great Vault gives max-level players an extra piece of gear for the content they did the week before. There are three rows: raid bosses, Dungeons and Instances on Heroic difficulty or higher (Timewalking counts too), and world activities, a row that used to be PvP. Every goal you reach in a row unlocks one more choice, up to nine in total, but you can claim only one item.

• The reward matches the content: raid bosses give raid gear, Mythic dungeons give Mythic dungeon gear, and world tasks can give delve or tier gear.
• Its item level is a little higher than that content normally drops.
• If a goal needs several runs and you mix difficulties, the vault uses the lowest run.
• If no item suits you, take 6 Thalassian Token of Merit or 1 Nebulous Voidcore instead. You need at least three unlocked choices to get the full amount of tokens.

The goals change from season to season. In Midnight Season 2 they are:

In Midnight, world activities include Delves, Prey, Ritual Sites, Special Assignments and the weekly meta quests that reward Pinnacle caches. Mythic dungeons also count toward the dungeon row (see Mythic+ Dungeons).

The vault sits in the current expansion's hub city. You can also open it from the Mythic+ Dungeons or Journeys tab of the Adventure Guide, or by right-clicking its icon on the world map.

Next to the Midnight vault, Vaultkeeper Elysa trades Thalassian Token of Merit for useful goods, such as a Chest of Gold, packs of 10 Champion or Hero Mistcrests, and the Miasmic Jewelbinder, which adds a gem socket (see Gems and Sockets).

The Great Vault was added in patch 9.0.2 for Shadowlands. It replaced two older weekly chests: the Grand Challenger's Bounty, tied to Mythic+, and the War Chest, tied to PvP. In the last week of an expansion's final season the vault gives no rewards, and it stays off until the next expansion's first season starts.
