Loot Bonus Rolls Arrive April 21 | 12.0.5 Kicks Off Season 1

Voidforge bonus rolls and the 12.0.5 loot economy

Patch 12.0.5 "Lingering Shadows" launched on April 21, 2026, and the headline gear system it shipped is Voidforge: a bonus-roll mechanic where Nebulous Voidcores buy a targeted re-roll on any defeated boss in raid, Mythic+, Bountiful Delves, or Nightmare Prey Hunts. Voidforge replaces every previous bonus-roll attempt this expansion, because instead of a flat random redraw it removes items you already own from the pool on a per-difficulty basis, then rolls from what is left. Four weeks in, every player on a serious gear chase has built a weekly Voidcore routine around it.

Key takeaways

• Voidforge bonus rolls cost 2 Nebulous Voidcores on raid bosses and 1 Nebulous Voidcore on Mythic+, Bountiful Delves, and Nightmare Prey Hunts. The same stockpile buys twice as many solo-content rolls as raid rolls.
• The weekly Nebulous Voidcore cap starts at 2 per week and grows by 2 each week through the season, so the cores you save early pay off later when the per-week cap is much higher.
• Each Voidforge roll presents the eligible items for that boss at that difficulty, and any item you have already obtained on that difficulty is removed from the pool. A roll on a slot you have already farmed returns a small set; a roll on a fresh slot returns the full pool.
• The Voidforge itself is built by completing the Artifice of Aggression intro quest and the An Elementary Voidcore weekly (six completions finish construction). Decimus, the domanaar NPC at The Howling Ridge in Voidstorm, hosts the questline and the bonus-roll vendor.
• Ascendant Voidcores are a separate currency used for the weapon-and-trinket upgrade lane. Only fully-upgraded (6/6) Hero or Myth-track pieces, or max-quality Radiance Crafted weapons and trinkets, can be made Ascendant Voidforged.
• Voidcores drop from Voidforge content (raids, M+, Delves, Prey Hunts), with weekly cadence governed by the cap above. There is no separate "weekly freebie" — the cap simply rises.

The sections below walk what a Voidforge roll actually does, where each Voidcore is best spent, and how the construction questline gates the system in the first place.

What a Voidforge bonus roll actually does

Voidforge is not a flat-random redraw. After you defeat a boss, you can spend Nebulous Voidcores at the Voidforge interface to roll a second loot drop from that boss at that difficulty. The roll draws from the boss's full loot table at that difficulty, minus any items you have already obtained at that difficulty. Once you obtain every eligible item at a difficulty, the bonus roll has nothing left to roll for that boss at that tier.

The slot-aware mechanic is what changes how bonus rolls used to work. Old bonus-roll systems gave you a flat 1-in-N chance of a specific item every roll; Voidforge gives you a 1-in-(remaining pool) chance. A roll on a slot you have already mostly cleared returns a small set, often with one or two items left, and the per-roll chance of hitting your missing slot is much higher. A roll on a slot you have barely touched returns the full pool, and the per-roll chance is lower but the expected value over multiple rolls is balanced because you do not waste rolls on items you already own.

The Nebulous Voidcore economy: cap, cost, and cadence

The per-roll cost is asymmetric by content type:

• Raid boss bonus roll: 2 Nebulous Voidcores
• Mythic+ end-of-key bonus roll: 1 Nebulous Voidcore
• Bountiful Delve bonus roll: 1 Nebulous Voidcore
• Nightmare Prey Hunt bonus roll: 1 Nebulous Voidcore

The weekly Nebulous Voidcore cap starts at 2 per week and grows by 2 each week for the remainder of the season. So week one of the season caps at 2 cores, week two at 4, week three at 6, and so on. Voidcores drop from the same Voidforge content (raids, M+, Delves, Prey Hunts), but the weekly cap is the binding constraint, not the drop rate. There is no separate "weekly freebie" — earlier coverage that described stackable freebie tokens conflated the cap-growth mechanic with a separate freebie system that does not exist in 12.0.5.

The practical implication: spend cores on solo content first if your stockpile is small, because the 1-core cost doubles your effective roll count compared to raid use. As the weekly cap rises through the season, the strategic question shifts to which raid bosses are worth the 2-core premium — usually whichever boss drops the trinket or weapon you actually need.

📌 Never spend a Voidforge roll on a Hero-track slot where you have already collected most of the loot pool. The bonus roll only rolls from items you have not yet obtained on that difficulty, so a Hero re-roll on a near-full slot has the worst value-per-core in the system. Save cores for empty Champion slots and full-pool trinkets.

Where to spend Voidcores for the best return

The four content types that take Voidcore rolls each have different value profiles:

1. Mythic+ end-of-key: 1 core per roll, M+ rewards already include a guaranteed end-of-key drop, so the bonus roll is a pure addition. Best per-core value for a player still building tier or filling Champion slots.
2. Bountiful Delves: 1 core per roll on tier-8-or-higher runs. The end-of-delve chest already pays Champion gear at tier 8; the bonus roll adds a chance at the same track or a Hero piece if the delve was a higher tier.
3. Nightmare Prey Hunts: 1 core per roll. Prey Hunts reward weekly veteran-to-champion gear plus a Beacon of Hope (used to summon Nullaeus in Torment's Rise for 30 Hero Dawncrests).
4. Raid bosses: 2 cores per roll. Spend here only when a specific boss drops a trinket or weapon you have been chasing for multiple resets, because the per-core price is the highest in the system.

For a returning player with a small Voidcore stockpile, the order is: M+ end-of-key first (highest value-per-core), then Bountiful Delve tier-11 (Gilded Stash + bonus roll combine), then Prey Hunts (Beacon of Hope payoff), then raid bosses last (only when chasing a specific item).

The Voidforge construction questline gates the bonus-roll system entirely. You unlock the questline at level 90 in Voidstorm, complete the Artifice of Aggression intro for Decimus at The Howling Ridge, and then complete the An Elementary Voidcore weekly six times to finish the Voidforge. Until construction is complete, the bonus-roll vendor is unavailable. The build itself takes six weeks at one weekly per character, so a fresh alt that starts the questline today has the Voidforge online by mid-season.

Ascendant Voidcores and the upgrade lane

Ascendant Voidcores are the second Voidforge currency, used not for bonus rolls but for the weapon-and-trinket upgrade lane. Only fully-upgraded (6/6) Hero or Myth-track pieces, or max-quality Sparks of Radiance crafted weapons and trinkets, can be made Ascendant Voidforged. The Ascendant Voidforge upgrade adds a unique on-equip effect and pushes the item level above the standard Hero or Myth ceiling.

For most alts, the Ascendant lane is a late-season concern: you need a Hero-track piece at 6/6 first, which requires a substantial Dawncrest spend. Mains chasing the Bursthold of the Twilight or the Voidlight Sigil should funnel Ascendant Voidcores into the weapon first, then the trinket. Build your Midnight Season 1 gearing floor if you want a single buy-in that covers both the Voidforge construction and the gear baseline that makes Ascendant upgrades worth the cores.

How bonus rolls fit the broader 12.0.5 loot economy

Voidforge is the bonus-roll layer on top of the standard 12.0.5 loot economy, which still runs on Dawncrests, Sparks of Radiance, Field Accolades from Void Assaults and Ritual Sites, and the Great Vault. A typical week looks like: clear your raid loot, fill the Great Vault rows, claim the Field Accolades from Void Strikes and Ritual Sites, craft or upgrade with Dawncrests, and only then spend Voidcores on the slots that the standard loot economy left empty. The bonus rolls are the fill layer, not the foundation.

The patch's other gearing systems still matter. Bountiful Delves at tier 11 drop a Gilded Stash with 7 Myth Dawncrests after Delver's Journey Rank 4. The Revival Catalyst converts a qualifying non-tier PvE armor piece into the equivalent tier slot. Sparks of Radiance craft 259-base weapons that upgrade to 272 with Hero crests or 285 with Myth. For a player coming back to Midnight this month, Voidforge is the new lever, but the existing levers all still work — and Voidforge is most effective when it sits on top of a full standard-economy week, not in place of one.

Frequently asked questions

When did the Voidforge bonus-roll system go live?

Patch 12.0.5 "Lingering Shadows" went live on April 21, 2026, with NA seeing a partial April 20 deployment followed by an April 22 maintenance window. Voidforge unlocks at level 90 once you complete the Artifice of Aggression intro quest at The Howling Ridge in Voidstorm.

How many Voidcores do I get per week?

The weekly Nebulous Voidcore cap starts at 2 per week in week one of the season and grows by 2 each week through the remainder of the season. So week one caps at 2, week two at 4, week three at 6, and so on. There is no separate "freebie" stack — the cap simply rises week-over-week.

Why do raid bonus rolls cost 2 cores when M+ rolls cost 1?

The per-roll cost is asymmetric by content type: raid bosses cost 2 cores per Voidforge bonus roll, while Mythic+, Bountiful Delves, and Nightmare Prey Hunts cost 1 each. The asymmetry exists because raid bosses drop higher-item-level loot, so the bonus roll has more value. Practically, this means a small Voidcore stockpile buys twice as many solo-content rolls as raid rolls.

Does the bonus roll repeat items I already own?

No. Each Voidforge roll presents the eligible items for that boss at that difficulty, and any item you have already obtained at that difficulty is removed from the pool. The bonus roll only rolls from items you have not yet collected on that difficulty.

What are Ascendant Voidcores and how are they different from Nebulous?

Nebulous Voidcores buy bonus rolls; Ascendant Voidcores upgrade weapons and trinkets. Only fully-upgraded (6/6) Hero or Myth-track pieces, or max-quality Sparks of Radiance crafted weapons and trinkets, can be made Ascendant Voidforged. The Ascendant upgrade adds a unique on-equip effect and pushes the item level above the standard ceiling.

Where do I spend Voidcores for the best return?

Mythic+ end-of-key first (highest value-per-core), then Bountiful Delves at tier 11 (Gilded Stash combines well with the bonus roll), then Nightmare Prey Hunts (Beacon of Hope payoff), then raid bosses last. Spend raid cores only when chasing a specific trinket or weapon — the 2-core cost is the highest in the system.

Do Voidforge bonus rolls share a weekly limit across characters?

The Voidcore drops are warband-bound, but the weekly cap is per character. Every alt has its own cap that starts at 2 and grows by 2 each week. The Voidforge construction questline must also be completed on each character that wants to use the system.

Is the Voidforge worth grinding on a fresh alt?

Yes, but pair it with the Revival Catalyst, the renown reward pieces, and the Bountiful Delves loop rather than treating it as a standalone shortcut. Voidforge is the bonus-roll layer on top of the standard loot economy. A fresh alt should focus on building Champion-track gear from the standard sources first, then spend Voidcores on the slots that did not fill via the Vault, the renown rewards, or the Catalyst.
