The Voidforge is a new player power system in Patch 12.0.5, built around two major parts of endgame progression. It gives players extra chances to roll for bonus items from eligible content and later opens a separate upgrade path for weapons and trinkets, allowing key pieces of gear to reach a higher item level than they normally would.
This guide breaks down the full Voidforge system step by step, including where to find it, how to unlock it, how the weekly construction quest works, where to get the required Voidcore materials, and how to use the forge once it becomes available. We will also cover Nebulous Voidcores, bonus loot rolls, the Ascendant Nilhammer, Ascendant Voidcores, catch-up rules, and the main mistakes to avoid when spending your Voidforge resources.
The Voidforge is not just another patch vendor you visit once and forget. In Patch 12.0.5, it becomes a new layer of Midnight Season 1 gearing, sitting between your normal loot drops, Great Vault choices, and late-season item upgrades. Its main value is simple: you get extra chances at useful gear from the content you already run, then later gain a way to push selected weapons and trinkets beyond their normal endpoint.
The system has three separate parts that are easy to mix up. First, you build the Voidforge through weekly construction progress tied to endgame activities. After that, Nebulous Voidcores let you make bonus loot rolls from eligible raids, Mythic+ dungeons, Bountiful Delves, and Nightmare Prey Hunts. Finally, Ascendant Voidcores are used for the high-end upgrade side of the system, mainly focused on fully upgraded weapons and trinkets.
That makes the Voidforge relevant even if you are not pushing the hardest content. Casual players get more loot attempts without relying only on weekly rewards, alts benefit from catch-up and warband-wide progress, and high-end players need to plan which trinkets or weapons are actually worth upgrading first. The mechanic itself is not hard, but understanding which Voidcore does what is the difference between using the system efficiently and wasting progress on the wrong expectation.
The Voidforge is located in Voidstorm, at The Howling Ridge. The easiest way to find it is to head to the forge platform near Decimus, who handles the early construction quests and later becomes your main point of contact for the system.
If you arrive at the location and cannot interact with Decimus or the forge properly, continue the Voidstorm campaign until the area and NPC become available. The Voidforge system starts from Decimus, so you need access to him before you can begin building it.
To unlock the Voidforge, speak with Decimus in The Howling Ridge and pick up the quest Building the Voidforge. This quest asks you to collect Elementary Voidcore Shards from Midnight Season 1 endgame content. These shards are fused into Elemental Voidcores through Transmute Elemental Voidcore, which powers the construction of the forge.
Elementary Voidcore Shards can be earned from three main sources:
Each turn-in requires 3 Elementary Voidcore Shards. After you collect them, return to Decimus to complete the quest and use Transmute Elemental Voidcore. The full unlock requires 6 Elemental Voidcores in total, so you repeat this process through the follow-up quest An Elementary Voidcore until the forge is fully constructed.
Progress toward the Voidforge is warband-wide, which makes the unlock much easier for alts. There is also full catch-up available if you missed earlier weekly progress, so you do not need to wait several more weeks just because you started late. Keep picking up An Elementary Voidcore from Decimus after each turn-in, continue running eligible endgame content, and the Voidforge will unlock once all six Elemental Voidcores have been completed.
After the Voidforge is fully built, Decimus starts the next stage of the system: the Ascendant Nilhammer. This tool unlocks the upgrade side of the forge and gives players access to Ascendant Voidcores, which are used to empower eligible weapons and trinkets beyond their normal upgrade cap.
The unlock starts with the quest New Tools, New Heights. Decimus gives you a Hungering Oblivium, which must be charged through Midnight Season 1 endgame content. You do not need one specific activity for this step, so the fastest route is simply to combine the content you are already doing for loot, Great Vault progress, or weekly character progression.
To fully charge one Hungering Oblivium, you need to complete any combination of three eligible activities. For example, you can kill three raid bosses, run three Mythic+ dungeons, clear three Bountiful Delves, or mix these sources together depending on what is fastest for your character that week.
The full Ascendant Nilhammer unlock requires 4 Hungering Oblivium charges in total. Since players can normally complete one charge per week, this part works as a four-week follow-up after the Voidforge itself is finished. Once the Ascendant Nilhammer is completed, you can start acquiring and using Ascendant Voidcores on eligible weapons and trinkets.
Nebulous Voidcores are the bonus roll currency of the Voidforge. Instead of waiting only for normal drops or weekly Great Vault choices, you can spend these cores after completing eligible content to receive an extra random item from that activity's loot pool. The item is based on your current Loot Specialization, so you should always check your spec before spending a core.
Bonus rolls become available after completing specific Midnight Season 1 content:
Once the Voidforge is complete, Decimus gives the quest A Nebulous Endeavour. This introductory quest asks you to acquire Nebulous Voidcores from Decimus and then spend one after completing eligible content.
Decimus offers 2 Nebulous Voidcores through exchange quests. You only need to choose one of the available payment options each week:
| Payment Option | Cost | Reward |
|---|---|---|
| Gold | 5,000 Gold | 2 Nebulous Voidcores |
| Voidlight Marl | 2,000 Voidlight Marl | 2 Nebulous Voidcores |
| Veteran Dawncrest | 80 Veteran Dawncrest | 2 Nebulous Voidcores |
The amount available to each character uses a rolling cap that increases by 2 every week for the rest of the season. This means late-starting characters can catch up instead of permanently missing earlier weekly purchases.
You can also get an additional Nebulous Voidcore from Vaultkeeper Elysa for 6 Thalassian Tokens of Merit. This extra purchase does not count against the weekly increasing cap, but you should complete the Decimus Voidcore quest first to avoid any launch-week tracking issues with the cap.
When you defeat an eligible raid boss, finish a Mythic+ dungeon, open a Bountiful Delve chest, or complete a Nightmare Prey Hunt while carrying Nebulous Voidcores, the game offers a bonus loot prompt. If you accept it, the system spends the required number of cores and gives you one random eligible item for your current Loot Specialization.
| Content | Nebulous Voidcore Cost | Bonus Roll Reward |
|---|---|---|
| Midnight Season 1 raid boss | 2 | Random item from that boss, matching your Loot Specialization and the difficulty killed |
| Mythic+ dungeon | 1 | Random dungeon item, with item level equivalent to the Great Vault reward for the completed Keystone level |
| Bountiful Delve | 1 | Random eligible Delve item, based on the completed Delve tier |
| Nightmare Prey Hunt | 1 | Random eligible Prey item from the Nightmare difficulty reward pool |
For Mythic+ specifically, Nebulous Voidcore rewards follow Great Vault item-level scaling for the completed Keystone level. For example, a Keystone level +10 or higher can reward a Myth track item through the bonus roll system.
Raid bonus rolls are more expensive because each boss has a smaller and more focused loot pool. Mythic+, Bountiful Delves, and Nightmare Prey Hunts cost only 1 Nebulous Voidcore per roll, while raid bosses cost 2.
The most important part of Nebulous Voidcores is duplicate protection. When you receive an item through a bonus roll, that item is removed from that specific bonus roll loot pool until you have received all eligible items from it. This protection is tracked per difficulty, so getting a raid trinket from a Normal boss does not remove the same trinket from the Heroic or Mythic version of that boss's pool.
Because of this, Nebulous Voidcores are best spent with a target in mind. Use them on bosses or activities with valuable weapons, trinkets, rings, or other high-impact items for your spec. Spending them randomly still gives extra loot, but the real value comes from shrinking the pool around the pieces you actually want.
Ascendant Voidcores are the high-end upgrade resource of the Voidforge. Unlike Nebulous Voidcores, they are not used for bonus loot rolls or extra item drops. Their only purpose is to empower eligible weapons and trinkets after the Ascendant Nilhammer has been completed.
Once the Ascendant Nilhammer is unlocked, Ascendant Voidcores can be earned from Midnight Season 1 endgame content. This includes raid bosses, Mythic+ dungeons, Bountiful Delves, and Nightmare-difficulty Prey Hunts. The system is aimed at players who already have strong gear pieces and want to push the most important slots a step further.
Only specific items can be upgraded with an Ascendant Voidcore:
This restriction is important. Ascendant Voidcores do not work on armor, rings, necks, cloaks, or partially upgraded items. If your weapon or trinket is still missing normal upgrade levels, you need to finish that upgrade path first before it can become eligible for the Voidforge upgrade.
| Item Type | Eligible for Ascendant Voidcore? | Requirement |
|---|---|---|
| Hero track weapon | Yes | Must be fully upgraded |
| Hero track trinket | Yes | Must be fully upgraded |
| Myth track weapon | Yes | Must be fully upgraded |
| Myth track trinket | Yes | Must be fully upgraded |
| Radiance Crafted weapon | Yes | Must be maximum quality |
| Radiance Crafted trinket | Yes | Must be maximum quality |
| Armor, rings, necks, cloaks, and other slots | No | These slots cannot use Ascendant Voidcores |
Using an Ascendant Voidcore turns the selected item into an Ascendant Voidforged item and increases its item level. After that, the item reaches its final Voidforge state and cannot be upgraded further through the normal upgrade system or through another Ascendant Voidcore.
Because this upgrade is tied to the strongest gear slots, you should not spend it casually. In most cases, your first Ascendant Voidcore should go into a weapon, especially if it is a Myth track weapon or a best-in-slot crafted weapon you are unlikely to replace soon. Trinkets are also strong targets, but they depend more heavily on your spec, content type, and whether the item is actually part of your long-term setup.
The Voidforge is straightforward once unlocked, but it can punish careless spending. The bonus roll window can appear after multiple eligible activities, so do not click it automatically unless you actually want loot from that specific boss, dungeon, Delve, or Nightmare Prey Hunt.
For most players, the best routine is simple: finish the Voidforge construction chain, buy your weekly Nebulous Voidcores from Decimus, use them only on loot pools that contain real upgrades, and save Ascendant Voidcores for fully upgraded weapons or trinkets that will stay relevant for the rest of Midnight Season 1.
