The Great Vault rewards effort across three separate tracks every week, but it only ever hands you one item. That single-pick rule is what makes Vault optimization a real decision rather than a chore. In Midnight Season 1, the smartest players are not grinding one activity to perfection. They are spreading the right amount of effort across Mythic+, raid, and PvP so that when reset hits, they have the highest-ilvl, most-useful item available to choose from. This guide breaks down how the three rows actually work together and when paying for a small boost to crack open a higher slot beats spending three more hours chasing the last key.

How the Great Vault works in Midnight Season 1

The Vault has three rows, one per activity, and each row can hold up to three reward slots. The slots within a row unlock based on how many qualifying activities you complete that week:

  • Mythic+ row: slots unlock at increasing dungeon counts, and the item level offered scales with the key level of your best completed runs.
  • Raid row: slots unlock by killing bosses, with ilvl tied to the difficulty (LFR, Normal, Heroic, Mythic) of the bosses that filled each slot.
  • PvP row: slots unlock from earning Honor or rated wins, with ilvl tied to your rating bracket at the time of reset.

At reset you get exactly one choice from everything shown. So the goal is not to max one row, it is to make sure the single best item across all nine possible slots is something you actually want and at the highest ilvl you can reach.

The core principle: breadth unlocks slots, depth raises ilvl

Two different levers control your Vault. Breadth (how many activities you do) decides how many slots appear. Depth (how hard those activities were) decides the item level each slot offers. Most players over-invest in one and ignore the other.

The optimal weekly shape for a typical raiding-and-pushing main looks like this:

  • Run enough Mythic+ to fill all three M+ slots, and make sure at least your top runs are pushed as high as you can reliably time.
  • Clear enough raid bosses on your highest comfortable difficulty to fill at least one, ideally two, raid slots.
  • Top up the third row with PvP, even if you are mainly a PvE player, because a few easy slots there give you extra lottery tickets at no real ilvl cost.

The reason this works: each filled slot is a free reroll on the loot table. A half-empty Vault throws away picks. Three rows with three slots each means up to nine candidate items to choose your single reward from, which dramatically raises the odds that one of them is an upgrade for a slot you actually need.

Should you push the last key or fill another row?

This is the question that decides most weeks. Say you have two timed keys at a solid level and you are short on time. Your two realistic options are:

  • Run one more dungeon to unlock your third M+ slot, giving you a third candidate item but only at the ilvl of your third-best key.
  • Push your existing keys two or three levels higher to raise the ilvl of the slots you already have.

The general rule: unlock empty slots first, then raise ilvl. An empty slot is worth zero. A filled-but-lower slot is a real choice. So early in your weekly play, prioritize breadth: get every row to at least one slot, then get M+ to all three. Once your slots exist, the marginal value shifts to depth, and pushing key level becomes the better use of time. The crossover point is simply whether you have empty slots left.

When a small boost beats the grind

There is a specific situation where buying a boost is genuinely the efficient move rather than a shortcut for its own sake. If you are one or two key levels short of the breakpoint that bumps your M+ slot into a higher reward tier, a single carried timed run at that level can be worth more than three lower keys combined. The same applies to the raid row when a couple of Heroic or Mythic kills would push a slot a full difficulty tier above what you can clear in your own group, and to PvP when crossing a rating threshold lifts the bracket your Vault pays out at.

In those cases the boost is not replacing your gameplay, it is converting your already-unlocked slots into meaningfully higher ilvl. PEWPEWSHOP offers exactly this as a safe, piloted-or-self-play Vault boost, so you can target a single high key, a difficulty tier, or a rating breakpoint instead of regrinding the whole week. Used surgically, that is often a better trade than burning an evening on keys that only fill slots you would never pick from.

A simple weekly checklist

  • Monday to Wednesday: unlock at least one slot in all three rows. Breadth first.
  • Midweek: fill the M+ row to all three slots, since dungeons are the most flexible and repeatable source.
  • Raid night: push your highest comfortable difficulty to lift raid-slot ilvl, not just clear LFR for participation.
  • Before reset: push your two best keys as high as you can time, since those set your top M+ ilvl candidates.
  • At reset: compare all nine potential slots and pick the highest-ilvl item for a slot you genuinely need, not just the biggest number.

One nuance on that last point: the highest ilvl item is not always the right pick. A slightly lower item with a much better stat profile or a tier-set piece for your spec can outperform a raw ilvl gain. Always weigh the actual character upgrade, not just the number.

FAQ

How many activities do I need for a full Great Vault?

To fill every slot you need to complete enough of each activity to unlock all three slots in all three rows. In practice that means several Mythic+ dungeons, multiple raid boss kills, and some PvP Honor or rated games each week.

Is it worth doing PvP if I am a PvE player?

Yes, for the extra slots. Even a few easy PvP completions add candidate items to your weekly pick at almost no time cost, which raises the chance that your one reward is an upgrade you actually need.

Should I always pick the highest item level from the Vault?

Usually, but not blindly. A lower-ilvl item with better stats for your spec, a missing tier piece, or a trinket that fits your build can beat a raw ilvl upgrade for a slot you do not care about. Pick the best character upgrade.

Does a boost ruin the value of the Vault?

No. A boost is most efficient when it converts slots you have already unlocked into a higher ilvl tier, for example a single high timed key or a difficulty-tier kill, rather than replacing all your weekly play. Used to hit a specific breakpoint, it is a clean efficiency gain.

Bottom line

Treat the Great Vault as a portfolio, not a single grind. Spread effort across all three rows to unlock the maximum number of slots, then push depth where it raises ilvl, and only reach for a targeted boost when a single high run or a difficulty tier would lift a slot you already own across a real breakpoint. Do that consistently in Midnight Season 1 and your weekly pick will reliably be one of the best upgrades in the game.
