The Voidforge allows players to spend Nebulous Voidcores on targeted bonus loot rolls and forge Ascendant Venomstones to elevate high-end weapons, trinkets, and necklaces beyond their normal track limits. Earning these upgrades involves gathering Ascendant Venomstones through endgame activities like Mythic+ dungeons, raids, Bountiful Delves, and Prey hunts.
How to Unlock the Voidforge
To unlock the Voidforge system, pick up the quest In the Catalyst's Shadow from Decimus in the Voidstorm and follow it to Orin Straylight in Silvermoon City. The introductory quest "In the Catalyst's Shadow" requires you to help Orin collect Voidcore Shards from current endgame content, including Mythic+ end-of-run chests, Bountiful Delves, and raid bosses.
Progressing through the quest chain requires helping Orin collect Voidcore Shards until your forge is fully constructed. Finishing this storyline unlocks access to bonus roll tokens and allows every character on your account to use the Voidforge. For players seeking to bypass the introductory grind, a Voidforge Unlock Boost can complete the required storyline quickly.
Nebulous Voidcores: Targeted Bonus Rolls
Once constructed, the Voidforge grants access to Nebulous Voidcore tokens that act as personal bonus rolls for current endgame encounters.
- Source: Orin Straylight trades one Nebulous Voidcore per week on each character for materials such as gold, Voidlight Marl, or Veteran Mistcrests.
- Dungeon Costs: Completing a Mythic+ dungeon requires one core charge to initiate a bonus roll.
- Raid Costs: Defeating a raid boss costs one core charge to trigger an extra roll.
- Loot Quality: Items awarded from dungeon rolls match the Great Vault item level for the completed keystone level, such as a Myth 1/6 piece from a level 10 run.
- Bad Luck Protection: Every encounter features a curated loot table based on your loot specialization, and once an item drops from a bonus roll, it is removed from that specific boss or dungeon pool to prevent duplicate rolls.

Ascendant Voidcores and Gear Upgrades
The Voidforge uses Ascendant Venomstones to supercharge fully upgraded equipment beyond standard item level thresholds. Collecting ten Ascendant Venomstones is required to upgrade a single piece of gear.
Only weapons, trinkets, and necklaces can receive an Ascendant Venomstone upgrade. Eligible gear must already sit at its maximum standard upgrade level—such as rank 6/6 on Hero or Myth tracks, or the highest rank for crafted gear—before it can be infused. Using an Ascendant Venomstone on an eligible item preserves all previously applied gems and enchantments.
Farming Ascendant Voidshards
Ascendant Venomstones drop from a selection of weekly and repeatable endgame sources:
- Mythic+ Dungeons: Completing any keystone at level +10 or higher guarantees an Ascendant Venomstone.
- Heroic and Mythic Raids: Every boss defeated in Heroic or Mythic raid difficulty drops a guaranteed Ascendant Venomstone.
- Bountiful Delves: Opening the end-of-run Bountiful Chest with a Coffer Key on Tier 11 awards a guaranteed Ascendant Venomstone.
- Nightmare Prey: Defeating Nightmare Prey awards a guaranteed Ascendant Venomstone from the Champion box.
