Diablo 4 Season 9: Fastest Forgotten Soul & Obducite Farm Route (2025 Guide)

If you aim to triple masterwork Diablo 4 gear in Season 9, you already know the pain: you will burn through Forgotten Souls and Obducite fast. Luckily, recent buffs and a couple of clever tricks have made farming these materials a lot easier—if you know what you’re doing. Here’s the most efficient way to stack up both Forgotten Souls and Obducite, with a reliable rotation that minimizes downtime.

 

🔥 Step 1: Farm Legion Events for Forgotten Souls

Why? Legion Events are now insanely rewarding. Thanks to buffs in recent patches, running one in Torment IV can give you:

• 200–250 Forgotten Souls
• Veiled Crystals
• Diablo 4 Boss summoning materials
• Ancestral loot

How often?
They spawn every 25 minutes and only take about 3 minutes to complete. That means you can easily farm up to 500 Forgotten Souls in an hour.

How to track them?
Use helltides.com to check upcoming Legion spawns. Set a timer and never miss one.

 

⛏️ Step 2: Farm Obducite Between Legion Events

While you’re waiting for the next Legion, fill the gap with Obducite farming. Here’s the tier list of options from best to worst in terms of time efficiency:

 

✅ Top Pick: Lair Boss Teleport Trick (Horadric Strongroom Bug Farming)

What to do:

1. Open a Nightmare Dungeon that includes a Horadric Strongroom (e.g., Uldur’s Cave).
2. Instead of running the whole dungeon, teleport to different Lair Bosses:
• Gregoire
• The Hanged Man’s Hall
• Urivar
• Varshan
• Lord Zir
• Harbinger of Hatred
3. If one of these has a purple flame, it means a Horadric Strongroom has spawned. Run it for massive Obducite (often 2,000–2,500 in a few minutes).
4. Repeat the loop and go back to the first lair after a full cycle—the Strong Rooms will have reset.

Why it works:
This skips full dungeon clears and directly targets the Obducite jackpot rooms, minimizing grind.

 

⚔️ Alternative 1: Tribute of Refinement in the Kurast Undercity

• Requires Tribute of Refinement tokens (from Lair Bosses or Whispers)
• Nets you ~2,000 Obducite in 2–3 minutes
• Run with friends or use the party finder to chain them quickly

 

🔥 Alternative 2: Infernal Hordes (8-Wave Runs)

• Best balance of Obducite vs. time
• Takes 10 minutes, gives 2,000–3,000+ Obducite
• Good source of Burning Aether
• Avoid 10-wave unless you’re targeting Aether specifically (they take 13 minutes)

 

⚠️ Less Efficient: Horadric Material Reserves in Nightmare Dungeons

• Horadric Chests can drop 15 Forgotten Souls, and other loot includes Diablo 4 gold
• Not guaranteed, and they’re scattered
• Better done while leveling Glyphs or on the side

 

🧠 Pro Farming Rotation

Here’s the smart rotation to maximize your efficiency:

1. Check helltides.com – note the time until the next Legion Event.
2. If you have 15–20 minutes:
• Start the Lair Boss loop to farm Horadric Strongrooms.
• Mix in Whispers or Tribute of Refinement runs if you have tokens.
3. When the Legion Event starts:
• Drop everything, run it for 250 Forgotten Souls.
4. Repeat loop.

This rotation ensures you’re never idle, always farming either Forgotten Souls or Obducite, and building the stash you need for Masterworking.

 

Final Thoughts

Triple Masterworking requires thousands of Obducite and tons of Forgotten Souls. The key is syncing your grind with the 25-minute Legion cycle and squeezing in the fastest Obducite sources during downtime.

Run smart. Stack hard—Masterwork without the burnout.
