The Great Vault Explained — Complete Guide for WoW Midnight Season 2

The Great Vault is the single most valuable weekly reward in the game, and it's also the system players misunderstand most.

Three rows. Up to nine items generated. You pick exactly one.

This guide covers how each row actually calculates your item level, the season-long raid mechanic that isn't in most guides, why your third world slot is stuck at Tier 1 no matter how many Delves you run, and what to take when none of the nine items are upgrades.

The Basics

The Horde-sector vault has no attendant. If you want to trade for currency or a bonus roll, use the neutral one.

Check it from anywhere: Adventure Guide (J) → Journeys tab → small Great Vault button in the top right. You can view progress remotely, but you still have to physically visit the vault to open it and pick.

Row Requirements

Every slot can roll a tier piece. This includes dungeon and world slots — you do not need to raid to get tier gear from your vault. Most players don't know this and skip the vault entirely on non-raid weeks.

Rewards unlock on the following reset. Complete objectives this week, choose next week.

The Raid Row

Lairs count toward the Raid row. Nymrissa Wavecaller in the Tidebound Grotto fills raid progress, which makes it the cheapest raid credit available — queueable solo on World difficulty.

Item level is set by the highest difficulty at which you completed each threshold. If you cleared 8/8 Normal but only 5/8 Heroic, your first two slots are Heroic quality and your third drops to Normal — because you didn't kill six Heroic bosses.

Raid Vault Item Levels

Vault rewards come from the loot table one difficulty above what you cleared. Heroic clears produce Myth-track gear. This is why Heroic raiding stays relevant for the entire season even in Mythic-progression guilds.

Your Raid Loot Pool Stays Open All Season

This is the mechanic that changes how you plan progression, and it isn't obvious from the UI.

Once you've killed a boss at a given difficulty, that boss's loot table stays unlocked for you at that difficulty for the rest of the season. It doesn't reset weekly.

Here's what that looks like in practice:

1. You kill boss 8 on Mythic in week 4.

2. In week 9 you only kill bosses 1 and 2 on Mythic, unlocking a single raid slot.

3. That slot can still roll loot from boss 8 — and from every boss before it.

Why this matters: if there's a specific trinket or weapon sitting on a late boss, you don't need to reach that boss every single week. Kill it once at your target difficulty, then fill the raid row with whatever's convenient. Your loot pool stays wide.

The same logic applies to killing bosses out of order. Join a group already in progress and kill boss 4 without killing 1 through 3, and your pool draws from all four.

Practical takeaway: early in progression, prioritise reaching the deepest boss you can at your best difficulty at least once. After that, filling raid slots becomes far more flexible.

The Dungeon Row

Heroic, Mythic 0, Mythic+, and Timewalking all count. Timewalking counts as Heroic.

Your three slots are set by your 1st, 4th, and 8th highest keys of the week. The order you run them in is irrelevant — the game sorts them for you.

Worked example. You run: +9, +9, +9, +7, +7, +5, +5, +5, +5, +4, +4.

To improve from there: three more keys at +6 or above raise your third slot, one at +8 or above raises your second, anything above +9 raises your first.

There's a useful consequence here. Once you've locked in eight keys, running additional low keys costs you nothing. Spam +2s to help friends and your earned item levels stay untouched.

Mythic+ Vault Item Levels

Two breakpoints are worth committing to memory:

+9 — Myth Mistcrests start here, not +10. If you're chasing crest currency and +10s are unreliable for your group, +9 delivers the same crest on a gentler timer.

+10 — the vault jumps to Myth 1/6 and stops improving. End-of-dungeon loot also caps at 311 from +10 onward. A +15 gives identical loot to a +10. Above +10 you're farming rating, not gear.

The World Row — Why Your Third Slot Is Stuck at Tier 1

This is the most common Great Vault frustration, and the cause isn't obvious from the interface.

The world row uses the same 1st / 4th / 8th highest logic as dungeons. And here's the catch:

Zone Events, Weekly Quests, and Assignments all count at Tier 1 Delve level.

So if your week looks like three Special Assignments, two Zone Events, then three Tier 8 Delves — your 8th highest activity is a Tier 1-equivalent weekly quest. Your third slot displays Tier 1, and running one more T8 Delve won't move it.

The fix: you need eight actual high-tier Delves or Prey hunts, not eight world activities of any kind. Weeklies and assignments fill the count but drag down the item level of your later slots.

World Row Item Levels

Prey hunts scale across Normal, Hard, and Nightmare and feed the same row. Normal Prey sits at Tier 1 Delve level.

What Counts and What Doesn't

Counts: Delves, Prey hunts, Zone Events, Weekly Quests, Assignments.

Doesn't count: world bosses and collection-style weekly quests. They feel like world content but never register toward the row.

When Nothing in Your Vault Is an Upgrade

Two alternatives, and one carries a requirement that catches people out.

Nebulous Voidcore (Bonus Roll)

Take a Voidcore instead of gear. Spend it for an extra loot roll on raid or Lair bosses, Bountiful Delves, Prey, or at the end of Mythic+ runs.

The requirement: you must have completed at least three Great Vault objectives to be offered a Voidcore at all. Fill only one or two slots and the option simply won't appear.

Bonus rolls drop at vault item level, not boss item level. A Voidcore spent on a Heroic raid boss yields Myth 1/6 — a full track above the direct drop. That's what makes them worth saving rather than spending casually.

When to take it: only when every vault option is a piece you already own at equal or higher item level. Early season, always take the gear — almost everything is an upgrade in weeks 1 through 4.

Thalassian Token of Merit

The currency alternative. These are items, not a true currency — they occupy bag slots, and you can only hold 12 at a time. Make room before you claim, or you won't be able to take the reward at all.

You receive more tokens the more objectives you completed. Spend them with Vaultkeeper Elysa beside the neutral vault:

The Miasmic Jewelbinder deserves more attention than it gets. A socket on a helm, bracer, or belt is a permanent stat gain on a piece you'll wear all season. Over a full season that outvalues ten crests on a piece you'll replace. If you have a locked-in tier helm or a best-in-slot belt, take the socket.

End of season: Thalassian Tokens are seasonal. When Season 3 opens they convert to gold at the same rate as the Chest of Gold, so there's no need to rush to spend them before the season closes.

What Should You Actually Take?

Work through this in order:

1. Is any option a slot upgrade or a tier piece that completes a set bonus? Take it. Set bonuses beat raw item level.

2. Is any option a weapon upgrade? Take it. Weapons carry the largest per-slot impact of any gear piece.

3. Are all nine options duplicates you already have at equal or higher item level? Take the Voidcore — assuming you filled three objectives.

4. Voidcore unavailable, or already sitting on several? Take Thalassian Tokens and buy a Miasmic Jewelbinder for a permanent socket.

5. Nothing above applies? Chest of Gold. Perfectly reasonable.

Weekly Routine to Maximise Your Vault

Raid row

• Kill 6 bosses at your highest reliable difficulty

• Include Nymrissa Wavecaller — it counts and it's queueable

• Early season, push to reach the deepest boss you can manage at least once to unlock its loot table for the season

Dungeon row

• Run 8 timed keys, ideally all at +10 so all three slots land at Myth 1/6

• Remember your 8th highest key sets your third slot — don't pad the count with low keys

World row

• Run 8 high-tier Delves or Prey hunts, not 8 mixed activities

• Weeklies and assignments count toward the number but cap those slots at Tier 1

• Skip world bosses for vault purposes — they don't register

Before you open

• Clear 12 bag slots if you plan to take Thalassian Tokens

• Check every row for tier pieces, not just the raid row

Common Mistakes

Padding the world row with weeklies. They count toward the number and cap the item level. Eight real Delves is the only route to three Tier 8 slots.

Taking a Voidcore in week one. Almost everything is an upgrade early in the season. Take the gear.

Skipping the vault on non-raid weeks. Dungeon and world slots roll tier pieces too.

Not clearing bag space. Thalassian Tokens are items with a hard cap of 12. Full bags means no reward.

Pushing above +10 to improve your vault. It doesn't improve. The vault caps at Myth 1/6 from +10 onward.

Re-clearing to late raid bosses every week. Once you've killed a boss at a difficulty, its loot stays in your pool for the season.
