Obducite
Primary · every roll
Spent on every Masterwork roll. The cost scales with the item's current Quality, plus a flat charge for the rank-25 Capstone step.
Masterwork
Gear improvement system explained — Quality scaling, Capstone Bonus, and material costs.
Heads up: material costs, exact ranks, and refund formulas are rebalanced every season. This page covers the system as a whole — for current values, check the Blacksmith UI in-game.
- Applied at
- Blacksmith (any major town)
- Eligible items
- Legendary, Unique, Mythic Unique
- Per-rank effect
- +% base stats & all affixes
- Endgame bonus
- Capstone +% to a random affix
Each Masterwork rank adds a flat percentage to the item’s base stat (Armor on armor, Damage on weapons, All Resistance on jewelry) and the same percentage to every affix value on the item. Ranks compound, so the final stages of an upgrade carry the most absolute power.
An upgrade attempt may grant more than one rank at once, so the actual number of clicks to reach max is fewer than the rank count.
Reaching maximum Quality unlocks the Capstone Bonus — a one-time, significantly larger boost applied to one random affix. It can land on a normal affix, a Tempered affix, or a Greater Affix, and the winning affix is highlighted in-game with a distinct color.
The Capstone stacks with Greater Affix bonuses, so an affix that is both Greater and picked by the Capstone carries both bonuses at once.
Veiled Crystal
Legendary / Unique upgrades
Salvaged from rare and legendary gear. Consumed alongside Obducite when Masterworking Legendary or Unique items.
Forgotten Soul
Mythic Unique upgrades
High-tier crafting material. Consumed alongside Obducite when Masterworking Mythic Unique items.
Abstruse Sigil
All upgrades
Required as a secondary cost across all Masterworking upgrades.
Neathiron
Capstone reroll
Rare boss material consumed when rerolling the Capstone Bonus to land it on a different affix.
Exact per-roll quantities and which secondary material applies to which item type vary by season. Check the Blacksmith UI for current values.
If the Capstone Bonus landed on a low-priority affix, you can reroll it to redistribute onto a different affix. The reroll does not reset your Quality progress — only the affix the bonus targets.
Reroll cost is paid in Obducite, a rare boss material (Neathiron), and Gold. The reroll is repeatable as long as you have the materials, so chasing a specific affix is a question of farming, not luck-locked progress.

Salvaging a Masterworked Legendary, Unique, or Mythic Unique at the Blacksmith returns a portion of the materials you spent. The refund scales with the item’s current Masterwork stage — not Masterworked, partially Masterworked, or fully Masterworked with Capstone applied — so a heavily upgraded item refunds proportionally more than a lightly upgraded one. The in-game salvage prompt previews the exact return.
Gold and reroll-only materials (e.g. the Capstone reroll’s rare component) are not refunded.
Mythic Unique salvage
Salvaging any Mythic Unique always yields one Resplendent Spark — even on a dropped item that was never Masterworked. Four Sparks craft a new Mythic Unique at the Alchemist.
TL;DR
Masterworking is the Blacksmith endgame system that pushes Legendary, Unique, and Mythic Unique gear past base values. Each rank multiplies stats and affixes; reaching max Quality unlocks a one-time Capstone Bonus on a random affix that stacks with Greater Affixes. If the bonus lands wrong, reroll it without losing Quality progress. Salvage refunds materials proportionally to how far the item was upgraded.
- Masterworking is applied at the Blacksmith and only works on Legendary, Unique, and Mythic Unique items.
- Every Quality rank boosts the item's base stat and every affix value. Stacking ranks compounds those boosts.
- Reaching maximum Quality unlocks a Capstone Bonus: an additional, larger boost to one random affix.
- The Capstone Bonus stacks with Greater Affix bonuses, so the same affix can carry both at once.
- If the Capstone lands on the wrong affix, you can reroll it without losing your Quality progress.
- Salvaging refunds a portion of the materials you spent — the refund scales with how much Masterworking the item has received.
- Exact costs, ranks, and material requirements change every season — check the in-game Blacksmith UI for current values.
