Maximize Efficiency: Start Here in Patch 12.0.5

Key Takeaways

• Voidforge is the headline gearing system of Patch 12.0.5 "Lingering Shadows" (live April 21, 2026). The unlock NPC is Decimus in Voidstorm, and the chain costs 3 Elementary Voidcore Shards per step, all farmable from raids, Mythic+, Bountiful Delves, and Nightmare Prey Hunts.
• Nebulous Voidcores are the bonus-roll currency. Spend 1 on a Mythic+, Delve, or Prey Hunt bonus roll; spend 2 on a raid-track bonus roll. Loot drops match your active Loot Specialization.
• The weekly Voidcore cap grows by 2 every week. Week 1 = 2 Voidcores, week 2 = 4, week 3 = 6, and so on for the rest of Season 1 — the catch-up curve is built in, so latecomers and alt-runners don't fall permanently behind.
• Vaultkeeper Elysa at the Great Vault sells one extra Voidcore per week for 6 Thalassian Tokens of Merit. Vendor-purchased Voidcores do not count against the weekly cap, so taking Tokens-of-Merit from the Vault when the loot options are weak is the better play.
• Voidforge progress is warband-wide; the Voidcore cap is per-character. Push alts through the Decimus unlock early to multiply your weekly bonus-roll throughput across the roster.
• Ascendant Voidcores arrive after the Ascendant Nilhammer follow-up — they upgrade already-maxed Hero, Myth, and max-quality Radiance Crafted weapons and trinkets past their normal item-level ceiling.
• Decor Duels (7v7 prop-hunt in Silvermoon), Void Strikes (Eversong Woods / Zul'Aman weekly rotation), Ritual Sites (1-5 player tiers), and Abyss Anglers (underwater fishing off Zul'Aman) round out the launch-week activity loop.

The week-by-week priorities below walk through the Voidforge unlock first, then the Voidcore spend strategy, then the rest of the 12.0.5 activity calendar.

Unlock the Voidforge: Decimus and Voidstorm

The first stop is the Voidforge unlock with Decimus in the Voidstorm zone. The questline runs in three steps, and each step asks for 3 Elementary Voidcore Shards turned in to Decimus before the next step opens. The Shards drop from any qualifying endgame activity:

• Raid bosses (any difficulty)
• Mythic+ end-of-run loot
• Bountiful Delves chest pulls
• Nightmare Prey Hunt completions

Three-boss LFR wings are the fastest first-week farm if you're not running M+ keys yet. Bountiful Delves at tier 8 or higher are the next-best low-prep option. Once you turn in the final Shard set, the Voidforge opens at Decimus' altar and the Nebulous Voidcore economy goes live.

✏️ Unlock tip: the Voidforge unlock is account-wide via the warband shared progress, but the Voidcore cap and the Voidlight Marl wallet are per-character. Push alts through the Decimus chain in the first ten days of the patch so their weekly Voidcore allotment isn't a wasted slot.

The Nebulous Voidcore Weekly Cap, Decoded

The per-character weekly Voidcore cap is the cap that actually matters for how fast your character gears. Blizzard's stated mechanic, quoted directly from the official 12.0.5 patch notes: "the total number of Nebulous Voidcores available to a character increases by two every week for the remainder of the season."

Concretely, that means:

• Week 1 (April 21-27): up to 2 Nebulous Voidcores per character.
• Week 2: up to 4.
• Week 3: up to 6. And so on for the season.

The cap is cumulative if you don't spend — missed weeks bank toward the cap, so latecomers don't have to start from zero. Decimus also sells Nebulous Voidcores directly for gold, Voidlight Marl, or Veteran Dawncrests, which lets you bridge a slow farming week without losing the weekly progress curve.

Vaultkeeper Elysa and the "Take Tokens" Pivot

The single biggest efficiency lever in 12.0.5 is the Thalassian Tokens of Merit option in the weekly Great Vault. If the Vault's loot picks are weak (off-spec, sidegrade item level, slot you already have), pick the Tokens. Vaultkeeper Elysa sits at the Great Vault and trades 6 Tokens of Merit for one Nebulous Voidcore.

The mechanical kicker: vendor-purchased Voidcores do not count against your weekly cap. So picking Tokens turns a weak Vault into one bonus Voidcore on top of whatever Decimus-driven Voidcore generation you're already on pace for.

The math on a strong-Vault week:

1. Loot picks worth taking from the Vault ⇒ take the loot; skip Elysa.
2. Two of three picks worth taking, one not ⇒ take the strongest loot; use Tokens from the third slot to buy half an extra Voidcore (Tokens accumulate; six unlocks one Voidcore).
3. None of the picks are upgrades ⇒ take Tokens on every slot, buy your free Voidcore, spend it on a bonus roll that targets a slot you actually need.

The detail continues below.

This is the lever that separates players who hit the weekly cap from players who exceed it. The Tokens path is where the season's compound advantage lives.

Where to Spend Your Voidcores

Nebulous Voidcores fuel bonus rolls on completed activities. Raid-track bonus rolls cost 2 Voidcores; Mythic+, Delves, and Prey Hunt bonus rolls cost 1 Voidcore. Drops respect your active Loot Specialization, so swap your loot spec before turning in if you're farming for an off-spec build.

• Mythic+ bonus rolls at the highest key level you can reliably time. The Vault's Mythic+ track scales with key level (higher keys = higher Vault track), and your bonus-roll item level scales the same way. Aim for the highest end-of-week key that doesn't risk a bricked timer.
• Raid bonus rolls on the final two bosses of your current clear difficulty. The trinket and weapon drops on the back half of the raid are usually the highest impact-per-bonus-roll spend.
• Delve bonus rolls at Bountiful Delve tier 8 or higher. The Delve loot table is narrow but reliable, and tier-8-plus Bountiful Delves are the easiest path to a tier set if your weekly cap is short.

Set your Loot Specialization before each bonus roll to direct the result. If you're a Frost Mage farming for Arcane catalyst conversions, swap to Arcane spec for the rolls, then back for the next pull.

Ascendant Voidcores: The End-of-Season Multiplier

The Ascendant Voidcore is the second-tier currency that unlocks after the Ascendant Nilhammer follow-up questline. Ascendant Voidcores push fully-upgraded Hero, Myth, and top-quality Radiance Crafted weapons and trinkets past their normal item-level ceiling — the only avenue to break the Season 1 hard cap on those slots.

The unlock cadence puts Ascendant Voidcores in reach during the back half of the season, after most players have cleared the Decimus chain and built a Nebulous Voidcore bank. Plan around two beats:

1. Don't over-spend Nebulous Voidcores in week 1. Bank a few against the Ascendant Nilhammer unlock for the Ascendant Voidcore conversion path.
2. Keep a fully-upgraded weapon target. Ascendant Voidcores are weapon and trinket coded; your goal slot for the Ascendant push should be locked in before you start spending.

With the Voidforge economics covered, the rest of the patch is the activity calendar wrapped around it — the events that feed Voidcore Shards back into the chain and the cosmetic side loops worth knowing about.

The 12.0.5 Activity Calendar Outside Voidforge

Four launch-week activity loops slot around the Voidforge grind:

• Void Strikes rotate weekly between Eversong Woods and Zul'Aman per the official patch notes. Once your first Void Strike completes in the active zone, turn in the immediate quests to unlock the follow-up Void Strike content for the rest of the week.
• Ritual Sites are 1-to-5-player instanced encounters with player-chosen difficulty tiers (the tier ladder scales up as you complete the lower ones). After your first Ritual Site clear, return to Silvermoon to unlock the next quest tier and increased completion rewards.
• Decor Duels is a 7v7 prop-hunt in Silvermoon City — hiders pick traps (Smoke & Mirrors, Song Bird, Sands of Time, Void Sphere); seekers pick event kits (Arcane Ranger, Nullifier, Spellbreaker). The mode is class-agnostic and rewards Illusionary Coins, redeemable for toys, mounts, and cosmetic gear.
• Abyss Anglers is a repeatable underwater fishing event off the coast of Zul'Aman — diving suit on, sunken treasure pulls, cosmetic and gear-upgrade rewards.

📌 Common mistake: burning weekly time on every activity at maximum effort. The fastest path is to clear one Void Strike, one Ritual Site at the highest tier you can solo or two-man, and one Bountiful Delve at tier 8 or higher — then convert any spare time into Decimus chain progress or a Mythic+ key for the Vault. Decor Duels and Abyss Anglers are cosmetic-grind side loops, not weekly priorities.

FAQ

Where do I unlock the Voidforge in Patch 12.0.5?

From Decimus in the Voidstorm zone. The unlock is a three-step quest chain, with each step costing 3 Elementary Voidcore Shards collected from raids, Mythic+, Bountiful Delves, or Nightmare Prey Hunts. The full chain takes a single play session on a max-level character with active Season 1 access.

How many Nebulous Voidcores can I get per week?

The cap starts at 2 per character in week 1 and grows by 2 every week for the rest of the season — week 2 is 4, week 3 is 6, and so on. Vaultkeeper Elysa at the Great Vault sells one additional Voidcore per week for 6 Thalassian Tokens of Merit, and those vendor-purchased Voidcores do not count against the cap.

Should I take Tokens of Merit or loot from the Great Vault?

Take Tokens whenever the Vault's loot picks are sidegrades, off-spec, or slots you already have a strong roll on. Six Tokens convert to one Nebulous Voidcore through Vaultkeeper Elysa, and that Voidcore does not eat your weekly cap, so converting a weak Vault into a targeted bonus roll is a strict efficiency win over taking a sidegrade.

What's the difference between Nebulous and Ascendant Voidcores?

Nebulous Voidcores fuel bonus rolls (1 per Mythic+/Delve/Prey Hunt, 2 per raid drop) and respect your active Loot Specialization. Ascendant Voidcores unlock later in the season after the Ascendant Nilhammer questline; they upgrade fully-maxed Hero, Myth, and Radiance Crafted weapons and trinkets past their normal item-level ceiling.

Is Voidforge progress account-wide or per-character?

The Voidforge unlock is warband-wide; once one character clears the Decimus chain, the system is open for the whole account. The weekly Nebulous Voidcore cap is per-character, so each max-level alt can claim its own weekly allotment. Pushing alts through the unlock early multiplies your bonus-roll throughput across the roster.

Where are Void Strikes happening this week?

Void Strikes rotate weekly between Eversong Woods and Zul'Aman. The active zone is posted on the in-game map and the patch's official news page. Once you complete one Void Strike in the active zone, the immediate follow-up quests open a chain of additional Void Strike content that runs through the week.

Is Decor Duels worth playing?

For cosmetics and toys, yes. Decor Duels is a 7v7 prop-hunt in Silvermoon City — class-agnostic, kit-based, low-stakes. The reward currency is Illusionary Coins, redeemable for the patch's mount, toy, and decor-themed cosmetic lineup. It is not a gearing path; treat it as the social-grind side loop after your weekly Voidforge work is done.
