Mythic+ and Great Vault rewards guide
Updated on
In Midnight Season 2 the Great Vault's dungeon row pays by key level: Mythic 0 gives Champion 4/6 (302), keys from +2 to +9 give Hero track from 305 to 315, and +10 or higher gives Myth 1/6 (318). Your three slots are set by your best, fourth best and eighth best runs of the week, so the eighth key matters as much as the first.
Active this week
Lindormi's Guidance
Xal'atath's Bargain: Ascendant+5
Fortified+7
Tyrannical+10
Key points:
- Higher keys mean better vault rewards, up to the weekly cap
- Slot thresholds are 1 / 4 / 8 completed dungeons
- Your three vault choices come from your 1st, 4th and 8th best runs
- Consistency across the week beats a single big push
VaultAlts shows your weekly run count and best key levels per character, so you know exactly which alt needs one more dungeon and at what level.
Key level to Great Vault item level, Midnight Season 2
| Key completed | Vault reward next week | Track |
|---|---|---|
| Mythic 0 | 302 | Champion 4/6 |
| +2 to +3 | 305 | Hero 1/6 |
| +4 to +5 | 308 | Hero 2/6 |
| +6 | 311 | Hero 3/6 |
| +7 to +9 | 315 | Hero 4/6 |
| +10 and higher | 318 | Myth 1/6 |
Two things follow. A +10 and a +14 put the same item in the vault, so above +10 the reward is rating, the teleport and the challenge, not gear. And the step from +9 to +10 is the only one that changes track, which is why the tenth key is the one worth a second attempt. Blizzard's own figure for the floor of the ladder is a Mythic 0 drop at 292, one step under its vault reward.
How the three dungeon slots are set
Each slot is priced at the lowest of the runs that fill it: the first slot by your best run, the second by your fourth best, the third by your eighth best. A worked week:
| Runs, best first | Slot | Set by | Vault item |
|---|---|---|---|
| +12, +10, +10, +9, +8, +7, +7, +5 | First (1 dungeon) | The +12 | 318, Myth 1/6 |
| Second (4 dungeons) | The fourth best, +9 | 315, Hero 4/6 | |
| Third (8 dungeons) | The eighth best, +5 | 308, Hero 2/6 | |
| +10, +10, +10, +10, +10, +10, +10, +10 | All three | Every slot's lowest run is +10 | 318, 318, 318 |
| +12, +10, +10, +9, +8, +7 | Third | Only six runs | Locked |
So the plan for three Myth choices is eight completed +10s, not one +15. The plan for one Myth choice is a single +10 on each alt you care about. What the whole vault pays across raid and world too is on how to get better Great Vault rewards, and which alt still has a cheap slot open on a given evening is what the Mythic+ tracker shows.
Where the affixes start in Season 2
Blizzard's live affix data, the same rows the affixes page renders, gives the starting level of each: Lindormi's Guidance in the entry keys, one Xal'atath's Bargain from +5, Fortified or Tyrannical from +7 with the other joining at +10, and Xal'atath's Guile from +12, where it replaces the Bargain. The +10 that changes the vault's track is therefore also the first key with both Fortified and Tyrannical active. The week by week order of the Bargains is on the affixes page as well.
Frequently asked questions
What key level do I need for Myth track from the Great Vault?
A completed +10 or higher in Midnight Season 2. Its vault reward is item level 318 on the Myth track, 1/6. Keys from +7 to +9 give 315 on the Hero track, 4/6.
Does a +12 give a better vault item than a +10?
No. Every key at +10 or higher gives the same vault reward, 318 Myth 1/6. Above +10 you are playing for rating, the dungeon teleport at a timed +10, and the harder affixes, not for a better vault item.
Do Heroic or Timewalking dungeons count toward the dungeon slots?
Yes, they count toward the 1, 4 and 8 dungeon thresholds, at their own item level, which is below a keystone run's. VaultAlts does not include them in its count, because it reads keystone runs from Blizzard's API.
Why do I need eight runs for three choices?
Because the third dungeon slot unlocks at eight completed dungeons, and its item level follows your eighth best run. With seven runs the third slot stays locked however high the keys were.
