Voidforge Bonus Rolling Like a Boss

The Voidforge just dropped with patch 12.0.5 and the chat is on fire. Everyone’s hyped about the power level boosts… until they realize those boosts are strictly limited. Without a plan, that shiny “bonus loot” button turns into the same impulsive trap that burned so many of us on Dawncrests and Sparks of Radiance last patch.

Bottom line up front: Treat your Nebulous Voidcores like the precious resource they are. Bonus roll smart or watch your limited stockpile vanish on mediocre upgrades while the real power sits untouched.

Let’s make sure we win this one.

Where to get Nebulous Voidcores

Once you finish the Building the Voidforge quest chain and unlock the thing, head to Decimus. You can buy Nebulous Voidcores with either Voidlight Marl or Veteran Dawncrests.

Starts at 2 per week
Increases by 2 each week for the rest of the season

Simple. Stockpile grows, but it’s still finite. Don’t waste it.

Where (and How) to Actually Use Them

You’ve got four main places to spend them:

Raids – costs 2 Voidcores per extra roll
Mythic+ Dungeons, Delves, or Prey – costs only 1 Voidcore

Loot quality tracks with the content:

Myth track → Mythic Raid or +10 Mythic+ Dungeons
Hero track → Heroic Raid or T8 Bountiful Delves
Champion track → Nightmare Prey

The golden rule: Spend your Voidcores on the highest difficulty content you actually clear regularly (or are about to push).

For me on Xendai the Guardian Druid, that means +10 Mythic+ Dungeons right now. My guild is still progressing Heroic Raid, so I’m not burning two cores per roll there yet. Once my Hero-track slots are full, I’ll have to decide: save for Mythic Raid rolls later, or chase S-tier Hero trinkets that beat my current A-tier Myth ones. I’m leaning toward saving… but I’ve been wrong before.

Make this decision today. Write it down. Future-you will thank you when the temptation hits mid-run.

But Where Exactly Should You Bonus Roll?

It depends. (I know, I hate that answer too.)

There’s no one-size-fits-all. The right answer shifts every week as your gear and Great Vault change. That’s why I built a quick process to calculate real odds instead of guessing.

Here’s the system I’m using:

For every loot table that can drop usable gear for your spec…
Count how many items you can actually equip (not just the one you want most).
Subtract any previous bonus rolls you’ve already used on that table from the number of items in it (the system has built-in duplicate loot protection).
Odds = (usable items / total available items) × 100
Roll on the table with the highest odds — then immediately recalculate after every roll and every new piece of loot.

It sounds a little nerdy, but it takes two minutes and dramatically tilts the odds in your favor. I might even throw together a simple spreadsheet later and share it if enough people want one.

What This Looks Like on My Guardian Druid

Let’s run the numbers for Nexus-Point Xenas (9 items total for my spec):

3 usable (hands, two rings)
9 total – 0 prior rolls
33.3% usable odds

Then I did the same for the other seven Mythic+ dungeons:

Windrunner Spire: 4/8 = 50% ← winner
Seat of the Triumvirate: 4/11 = 36.4%
Maisara Caverns: 2/6 = 33.3%
Algeth’ar Academy: 2/8 = 25%
Pit of Saron: 1/8 = 12.5%
Sky Reach: 1/9 = 11.1%
Magister’s Terrace: 1/7 = 14.3%

Right now, Windrunner Spire is where my first few bonus rolls are going. The moment I loot a new usable Myth-track piece, I’ll rerun the math and the target might shift.

But Wowhead says...

Yeah, I saw it too. Wowhead recommends Mythic Dreamrift for the trinket/weapon and Algeth’ar Academy for the puzzle box.

Here’s the thing: I’m not running Mythic Dreamrift this week (or next). And a Myth-track puzzle box can wait.

Wowhead gives solid generalized advice that works great for most people. I’m just playing the personal odds for my character, my current gear gaps, and my actual raid schedule. Your mileage will vary — use the tool that fits how you play..

Final Verdict

Don’t let the hype train make you blow your Nebulous Voidcores on whatever pops up first. Run the numbers, pick your targets based on what you actually clear, and adjust with each bonus roll and gear score.

Play the odds. Stay disciplined.

Good luck out there — and may the (real) odds be ever in your favor.
