Season 11 brought major changes to master crafting in Diablo IV. While upgrading items is now far more straightforward, Obducite drops were heavily reduced across most activities. Because of this, knowing where and how to farm Obducite efficiently is more important than ever. This Diablo IV Season 11 Obducite Farming & Master Crafting Tips guide explains the fastest and most reliable method to farm Obducite in Season 11 and how it ties into the updated master crafting system.
Diablo IV Season 11 Obducite Farming & Master Crafting Tips
Obducite
Obducite is a high-tier crafting material used exclusively for master crafting gear. It is required to upgrade items at the Blacksmith and is essential for pushing legendary and unique items to their full potential.
To use Obducite, take a legendary or higher-quality item to the Blacksmith and select the Master Crafting option. Each upgrade consumes Obducite, improving the item’s stats in a predictable and streamlined way compared to earlier seasons.
In short, Obducite is no longer hard to use, but it is much harder to acquire efficiently if you rely on outdated farming methods.
Obducite Drops in Season 11 Explained
In Season 11, the amount of Obducite required per upgrade was reduced significantly. To balance this, Blizzard also reduced Obducite drops from nearly all sources.
Previously, a Nightmare Dungeon at higher difficulty could drop around 1,000 Obducite. In Season 11, the same dungeon now drops roughly 70–80 Obducite. Similar reductions apply to Hell Armies and the Kurast Underground City.
At first glance, this makes Obducite farming feel extremely slow. However, one system was clearly designed to replace all other methods: the Horadrim Vault.
Why the Horadrim Vault Is the Best Obducite Farm
Nightmare Dungeons that include the Horadrim Vault Room attachment reward dramatically more Obducite than any other activity in the game.
While standard Nightmare Dungeons, Hell Armies, and Kurast content all give reduced Obducite, a single completed Horadrim Vault can drop nearly 20 to 30 times more Obducite than those activities, in a fraction of the time.
This makes Horadrim Vaults the single best Obducite farming method in Season 11.
How to Get Nightmare Dungeon Keys with Horadrim Vaults
Nightmare Dungeon Keys are obtained from multiple sources, including chests, seasonal rewards, and general endgame activities. However, the modifiers on these keys are completely random.
Because of this, you should focus on rerolling and crafting keys efficiently:
- Craft Nightmare Dungeon Keys at the Occultist
- Salvage keys with unwanted modifiers
- Use the recovered materials to create new keys
Your goal is to obtain a Nightmare Dungeon Key that specifically includes the Horadrim Vault Room modifier. No other modifier comes close in value for Obducite farming.
Understanding Nightmare Dungeon Keys and Vault Modifiers
When you right-click a Nightmare Dungeon Key, the map opens and highlights the dungeon it unlocks. Each key includes multiple modifiers, such as bonus experience, gold, or item drops.
The modifier you are looking for is clearly labeled as Horadrim Vault Room. If a key does not have this modifier, it is generally not worth using for Obducite farming in Season 11.
How to Access and Complete the Horadrim Vault Room
Once you activate a Nightmare Dungeon with the Horadrim Vault modifier, enter the dungeon as normal.
Inside the dungeon, a purple trail will guide you toward the Vault entrance. The trail becomes more visible as you approach the correct location.
When you reach the Vault entrance:
- A portal structure appears
- Clear the enemies around it
- Activate the portal
Entering the portal transports you into the Horadrim Vault.
Horadrim Vault Mechanics and Strategy
Inside the Vault, you are presented with six upgrade options and allowed to choose three. These upgrades affect your performance inside the Vault and should be chosen to maximize speed and survivability.
Once inside:
- You have 90 seconds
- Kill as many enemies as possible
- Complete objectives as fast as you can
Speed-focused builds perform best here. Mobility, area damage, and fast clear times matter far more than raw toughness.
At the end of the timer, you fight a mid-level boss. Killing this boss spawns a reward chest.
Horadrim Vault Rewards and Obducite Gains
The reward chest at the end of a successful Vault run contains:
- Legendary items
- Unique items
- Jewels
- Large amounts of Obducite
At maximum Vault completion, the chest drops around 2,700–2,800 Obducite.
For comparison:
- Standard Nightmare Dungeon: ~70–80 Obducite
- Infernal Armies (full clear): ~300–400 Obducite, taking far longer
- One Horadrim Vault: ~2,780 Obducite in 90 seconds
One Vault run is roughly equivalent to completing around 30 standard Nightmare Dungeons.
Best Farming Loop for Season 11
For optimal efficiency:
- Craft and reroll Nightmare Dungeon Keys until you get Horadrim Vault modifiers
- Ignore other Obducite sources unless you need variety
- Run Vaults back-to-back with a speed-focused build
- Spend Obducite only on items you intend to keep long-term
This loop minimizes time investment while maximizing crafting progression.
Season 11 dramatically shifted how Obducite farming works. While most activities now feel unrewarding for crafting materials, the Horadrim Vault completely replaces them as the primary source.
