Masterworking isnโt a new mechanic toย Diablo 4, but as of Season 4ย Lootย Reborn, the system has been slightly altered.ย In the past, Masterworking would be present in allย stages of the game.ย It was a surefire way to upgrade, say,ย a weapon to keep it relevant for a little longer until you at least found a replacement.ย During the endgame, youโdย Masterworkย your gear toย ekeย out moreย performance.ย Youโllย engage with Masterworking in a similar manner, but itโs strictly an endgame mechanic now, tied with Tempering.
Diablo 4: How to Masterwork Your Gear (& What it Does)
What is Masterworking?

Originally, any blacksmith you visit inย Diablo 4ย could Masterwork your gear a handful of times, andย each time,ย the stats would increase by 5%.ย This was across the board and wasย prettyย nice, especially when you could do it as many as four or five times.ย The stat increase to an itemโs affix is unchangedโ5% each time you Masterwork your gear.
However, in Loot Reborn, you can now Masterwork an item as many as 12 times, which is the maximum.ย Furthermore,ย everyย 4th Masterwork, only one of the affixes will be chosenย at randomย and boosted by 25%ย as opposed toย 5% for every stat.ย Theย interestingย part is thatย an affix can receive the same boost severalย times,ย if youโre lucky.
Of course, the chances of that happening are slim, but unlike Tempering, you can wipe the slate clean and try again. For example, if you were hoping to get a 25% increase to minion damage, but didnโt, you can reset it. Youโll have to farm the materials again, but at least your item wonโt be bricked.
How to Masterwork Gear in Diablo 4

Sounds exciting, right? Well, to start Masterworking your gear in Diablo 4, youโll need to start with Tempering. To be specific, you have to Temper an Ancestral Legendary or Uber Unique to the maximum. Only then will an item be ready for Masterworking.
The next step is to unlock World Tier 4 (Torment) and start participating in The Pit of Artificers. Itโs a timed dungeon that has you slaying monsters to fill a meter, and when itโsย full, youโll face off against a boss. If youโre aย Diablo 3ย veteran, itโs essentially Nephalem Rifts.
Should you defeat said boss, theyโll drop Masterworking crafting materials, such as:
- Obducite: Required for Masterwork ranks 1 through 4.
- Ingolith: Required for Masterwork ranks 5 through 8.
- Neathiron: Required for Masterwork ranks 9 through 12.
In addition to the various ores, youโll also need standard crafting materials you get from breaking down gear, like Coiling Wards, Forgotten Souls, Abstruse Sigils, and Baleful Fragments. Afterwards, a blacksmith will gladly Masterwork your gear in Diablo 4.
