Obducite is one of the most valuable materials in Diablo IV Season 12 because it's directly tied to Masterworking and upgrading high-end gear. One thing many players have noticed is that Obducite simply feels harder to accumulate in Season 12. Compared to earlier seasons, you can't rely on casually earning it from almost every activity anymore. Instead, the material feels tied more strongly to specific farms, which means it helps to focus on a couple of efficient activities rather than spreading your time across everything Diablo 4 Items.

Nightmare Dungeons are still one of the most reliable ways to gather Obducite, but the results can vary depending on the sigil you use. The best scenario is when you get a dungeon with the Treasure Breach affix. This modifier fills the dungeon with Treasure Goblins, and those goblins can drop surprisingly large amounts of Obducite when defeated. A good run with several goblins can easily produce a few thousand Obducite in one clear. The downside is that Treasure Breach sigils aren't very common, so most of the time you'll still be running standard Nightmare Dungeons while hoping to roll one of these high-value versions.

Infernal Hordes is another activity that many players rely on this season, especially if they want to farm materials and gear at the same time. The mode throws waves of enemies at you, and as you clear them you earn Burning Aether. At the end of the run you can spend that Aether on different reward chests, including Spoils of Materials. These chests can drop a decent amount of Obducite along with other crafting materials. If you can handle higher difficulties and longer wave runs, the rewards get better, so this activity works well for players who want both upgrade resources and potential gear upgrades in a single run.

Players who own the Diablo IV: Vessel of Hatred expansion have another option through Kurast Undercity. Running this activity with a Tribute of Refinement can be a very focused way to farm Obducite. The dungeon is timed and involves moving through several stages before defeating a boss, and your rewards depend on how efficiently you complete it. With a high Attunement level and higher Torment difficulty, players often report getting a few thousand Obducite from the final chest. It's not the easiest content in the game, but if you have a strong build or a coordinated group, it can be one of the more consistent sources.

Another method that players still use involves hunting for Horadric Strongrooms. These special events can appear inside certain Nightmare Dungeons and usually reward a large burst of materials when completed. Some players focus on crafting or rerolling sigils until they find ones that are more likely to contain Strongrooms, then quickly check the dungeon and rush the event when it appears. Even though Strongrooms were toned down compared to earlier seasons, they can still give thousands of Obducite in a relatively short amount of time, which makes them worth targeting.

Outside of these main farming methods, there are a few smaller sources that can help keep things moving. Running regular Nightmare Dungeons while searching for better sigils still gives some Obducite. Activities like Helltides, Legion events, and Whisper rewards can also supply useful materials and sigils that feed into your main farming loop. Even Treasure Goblins in the open world are worth chasing this season, since they seem to drop Obducite more often than before.

In practice, the best approach is to build a routine that combines the most rewarding activities. For example, you might run Helltides or Legion events to gather sigils and materials, then use those sigils to hunt for Treasure Breach dungeons or Strongrooms. When you feel like pushing harder content, you can mix in Infernal Hordes or Kurast Undercity runs for larger payouts diablo 4 season 12 uniques. By sticking to activities that give the most Obducite per run, you can keep your Masterworking upgrades moving forward even in a season where the material is meant to be scarce.
