Raid Lockouts, Bonus Rolls and the Weekly Reset in WoW

Raiding in World of Warcraft runs on a weekly clock. Loot chances, saved progress, bonus rolls and the Great Vault all refresh on the same day, and a lot of wasted effort comes from not knowing exactly what resets, when, and what carries over. In Midnight Season 2, with Venomous Abyss and the single-boss raid The Unbinding of Kith’ix both in rotation, getting the weekly routine right is worth more than an extra hour of farming.

The weekly structure is also why organised groups, guild alt runs and even a wow raid carry service all plan around the same reset day: whatever the group, the loot window opens and closes on a fixed schedule.

This guide covers the reset itself, how raid lockouts and saved IDs behave, how Nebulous Voidcore bonus rolls fit in, and how the raid row of the Great Vault turns a week of kills into a guaranteed choice.

When the weekly reset happens

The reset is region-based. Everything weekly refreshes at the same moment for your whole region.

The difference of a day between regions also explains why patch dates are usually listed separately. Patch 12.1.5 The Promise of Tomorrow arrived on 13 October 2026 in North America and 14 October in Europe, matching each region’s maintenance window.

How lockouts and saved IDs work

A lockout is the game’s way of limiting how often you can earn loot from a boss. The rules differ by difficulty, and the details matter if you play more than one character or raid with more than one group.

The Mythic rule is the one that catches people out. Once your character kills a Mythic boss, it is saved to that group’s instance for the rest of the week. If you join a different group whose progress does not match, you may not be able to enter, or you may find bosses already dead. Guilds therefore ask raiders not to join outside Mythic groups on their main characters before the guild’s own raid night.

You can check which IDs a character is saved to in the Raid Information panel. It lists each instance, difficulty, and the time left until the reset clears it.

Bonus rolls: the Nebulous Voidcore

Midnight’s bonus roll currency is the Nebulous Voidcore. Using one after a boss kill gives an extra chance at loot from that boss, on top of the normal drop. It is the single most useful tool for chasing a specific trinket or weapon, since a boss you can only loot once a week still gets two chances per kill.

In Season 2 there is an additional source. From the week of 6 October, a vendor named Orin Straylight sells one extra Nebulous Voidcore per week, purchasable with one of three currencies:

• gold
• Voidlight Marl
• Veteran Mistcrests

Because the extra core is capped at one per week, it pays to buy it every week rather than letting the opportunity lapse. A sensible habit is to save Voidcores for bosses that drop the items you need most, rather than spending them on the first kill of the night.

The raid row of the Great Vault

The Great Vault is the weekly reward chest that opens after the reset. It has separate rows for raids, dungeons and outdoor content, and each row fills slots based on what you completed in the previous week.

For raids, the usual structure is that killing more bosses unlocks more choices, with the item level of each choice based on the difficulty of the bosses killed. The vault then offers one item from the options you unlocked across all rows. In practice:

1. Kill bosses during the week on any difficulty.
2. At the reset, the raid row shows options that match those kills.
3. Pick one item from all the vault options you unlocked.

Kith’ix is an interesting case here. As a single-boss raid, it contributes only one kill per difficulty per week, so it works best alongside Venomous Abyss rather than as a standalone way to fill the row.

The Season 2 calendar around the reset

Several of the season’s changes are tied to specific weekly resets rather than patch day. The reference points:

Ascendant Venomstones drop from Heroic and Mythic raid bosses, among other sources, and ten of them upgrade a fully upgraded Hero or Myth weapon, trinket or necklace. Removing the crest cap means upgrade materials no longer stop at a weekly ceiling, which makes every raid kill after that date more valuable for catch-up.

Common lockout mistakes

Most lockout problems come from a small set of habits. The first is accepting a Mythic invite on a main character mid-week without checking which ID it belongs to, which can leave a raider locked out of their own guild’s progress. The second is treating Raid Finder as free extra loot: re-queueing for a wing you have already looted still lets you help the group, but your own loot chance for those bosses is spent. The third is forgetting that each difficulty has its own lockout, so a Heroic kill does nothing for your Mythic save and vice versa. A quick look at the Raid Information panel before every invite avoids all three, and it takes less time than a single pull.

A weekly routine that works

Putting the pieces together, a simple routine looks like this:

• Open the Great Vault first after the reset and pick your item.
• Buy the extra Voidcore from Orin Straylight.
• Raid with your main group before joining other Mythic groups.
• Spend Voidcores on bosses with your top-priority drops.
• Check saved IDs before accepting an invite to a second run.

None of this is complicated, but the reset punishes forgetfulness: a skipped Voidcore purchase is simply lost once the next reset comes around, and kills made on the wrong saved ID cannot be undone. Treat the reset day as a short checklist and the rest of the week becomes much more productive.
