How to Farm Forgotten Souls in Diablo 4 Season 10?

Forgotten Souls are a core crafting material used for Masterworking, and Season 10 finally gave players a consistent, repeatable way to farm them outside of Helltides. In this D4 Forgotten Soul farming guide, we'll bring you 6 best ways to get Forgotten Souls.

 How to Farm Forgotten Souls in Diablo 4 Season 10?

Forgotten Souls are a rare endgame crafting material used primarily for upgrading and perfecting high-tier gear. They’re essential for Enchanting and Masterworking Ancestral and D4 Mythic Unique items, making them one of the most valuable resources in Diablo 4’s late game.  The current best strategy combines Nightmare Dungeon farming, sigil cycling, and secondary sources like Legions, Chaos Rifts, and Mercenary Den trades. Let’s go over each method:

1. Nightmare Dungeons 

The Horri Material Reserve Nightmare Dungeon is currently the most efficient source of Forgotten Souls.

• Each run takes 2–3 minutes and can yield 100–200 Forgotten Souls just from hidden material chests scattered throughout the dungeon.

• You can find up to 10–12 chests per run, each dropping around 14–18 Forgotten Souls.

• Playing in a group is highly recommended since you can share sigils and clear faster while spotting more chests on the minimap.

• Use a slower build (like Spiritborn Evade Druid) so you don’t miss any chests — Sorcerers tend to move too fast and skip them.

• By maintaining a consistent route and exploring the entire dungeon map, you can average 2,000–3,000 Forgotten Souls per hour, all while casually farming.

Tip: Always check your minimap — an orange star icon marks a chest your teammates opened, so don’t miss them.

2. Sigil Crafting and Salvaging

To chain-run Nightmare Dungeons efficiently, you’ll need a large supply of Sigils. Salvage useless Sigils (like low-tier or irrelevant modifiers such as “Gem Reserve”) to craft new ones. Keep any Sigils that contain Chaos Rift or Material Reserve modifiers, as these can spawn chests or additional Forgotten Soul drops. Farming in a party helps keep everyone supplied — each player can contribute different Sigils, letting you rotate endlessly. If you run out of Sigils, farm Chaos Rifts or use Tree of Whispers bounties to get more.

3. Veiled Crystal Management

While farming Forgotten Souls, you’ll notice Veiled Crystals become your next bottleneck. The fastest method for Veiled Crystals is Tormented Boss farming — summon bosses using your crafting mats, then salvage all Uniques you get. This will supply hundreds of Veiled Crystals per session and keep your Masterworking loop balanced. The Tree of Whispers also gives small amounts (200–300 per turn-in), which helps between dungeon runs. Forgotten Souls become abundant before Veiled Crystals, so plan your materials accordingly.

4. Chaos Rift & Helltide Integration

While not the focus of this method, Chaos Rifts inside Helltides or Nightmare Dungeons can supplement your Forgotten Soul income.

• Helltide chests and Chaos Rifts both drop additional crafting materials, including Forgotten Souls.

• When you run Chaos-modified Sigils, you’ll naturally trigger Chaos Rifts during your dungeon farming.

• If a Helltide overlaps your run, clear a few Rifts before returning to your main loop.

5. Bounties & Legion Events

• Legion Events are one of the best side activities — each one gives about 250 Forgotten Souls, takes 2 minutes, and spawns roughly 3 times per hour.
  → That’s another ~750 Forgotten Souls/hour if you rotate properly.

• Whisper bounties (Tree of Whispers) often include dungeons or world events that drop a few hundred materials per completion.

• If you see a red bounty marker on a Nightmare Sigil, it means it’s active for Whispers — do it for bonus materials and XP.

6. Mercenary Den Trading

Don’t overlook your Mercenary Den. You can exchange Den Tokens for Salvage Material Cages, which can reward 10–25 Forgotten Souls each. These trades also have a chance to grant aspects, weapons, or even max-roll gear, so check regularly. While it’s not the main method, it’s a reliable passive source when you’ve stockpiled Den resources from other activities.

FAQs of Forgotten Souls

1. What is the most efficient way to farm Forgotten Souls?

The most efficient method is farming Nightmare Dungeons, especially Material Reserve or Horrid Material Reserve dungeons, where multiple “Forgotten Soul chests” spawn. Players can earn 2,000–3,000 Forgotten Souls per hour when running these dungeons efficiently in groups. Participating in Legion Events and Chaos Rifts between dungeon runs can further increase the total yield.

2. Can you get Forgotten Souls from Salvage?

Yes. Salvaging five-star (high-quality) or Ancestral Legendary items can return Forgotten Souls. This is especially useful when you’re overflowing with Legendary drops from endgame content, as salvaging unwanted items becomes an additional passive source of Souls.

3. What are Forgotten Souls used for?

Forgotten Souls are mainly used at the Blacksmith and Occultist:

• At the Occultist: To Enchant a Legendary or Unique item, rerolling one affix for a better one.

• At the Blacksmith: To Masterwork Ancestral or Mythic Unique gear, increasing the power of all affixes up to Rank 12. The cost ranges from 3 to 15 Forgotten Souls per rank, depending on the level. They’re also needed to reset Masterwork ranks, which requires 5 Forgotten Souls along with Veiled Crystals and Diablo 4 gold.
