Forgotten Souls have always been one of Diablo 4’s most coveted crafting materials. Used for Masterworking and Enchanting high-end gear, they’re critical for players chasing perfect rolls on Ancestral or Mythic Unique items. Until recently, they were locked almost exclusively behind Helltide events, forcing players to rely on limited windows and unpredictable spawns.

That finally changed in Season 10. With the new repeatable farming systems, players can now gather Forgotten Souls consistently without waiting for Helltides. This guide will cover the six best methods to farm Forgotten Souls in Diablo 4 Season 10, helping you maintain a steady supply for crafting and upgrading.

What Are Forgotten Souls in Diablo 4?

Forgotten Souls are a rare endgame Diablo IV material essential for late-game progression. They’re used to enchant gear at the Occultist and Masterwork high-tier equipment at the Blacksmith, pushing items to their full potential.

As you begin upgrading Ancestral or Mythic Unique gear, you’ll quickly find yourself running low on these Souls. With Masterworking costs ranging from 3 to 15 Forgotten Souls per rank, and additional costs to reset Masterwork levels, efficient farming becomes a must for any serious endgame player.

1. Nightmare Dungeons – The Best Source for Forgotten Souls

The Horri Material Reserve Nightmare Dungeon has become the go-to spot for serious Forgotten Soul farming in Season 10. It offers both quantity and speed, with chests and hidden caches providing massive amounts of Souls per run.

· Average run time: 2–3 minutes

· Souls per run: 100–200 (from hidden material chests)

· Chests per run: 10–12

· Souls per chest: 14–18

That translates to an average of 2,000–3,000 Forgotten Souls per hour, making it the most efficient farming method by far.

Tips for Running Nightmare Dungeons Efficiently

· Play in a group. This not only speeds up runs but also helps locate more chests through shared minimap visibility.

· Watch for orange stars on your map. These indicate chests opened by teammates. Don’t miss them!

· Use slower exploration builds. High-speed builds like Sorcerers often skip hidden chests. A slower, tankier build (such as a Spiritborn Evade Druid) ensures you clear every area.

· Rotate Sigils. Have each group member bring different Sigils to maximize your dungeon options and reduce downtime.

2. Sigil Crafting and Salvaging

Sustaining endless dungeon runs requires a steady stream of Nightmare Sigils. Managing your Sigils efficiently is key to keeping your Forgotten Soul income consistent.

· Salvage any low-tier Sigils or those with poor modifiers (e.g., Gem Reserve) at the Occultist to recover crafting materials.

· Craft new Sigils that feature Chaos Rift or Material Reserve modifiers—these often spawn additional Forgotten Soul chests or resource nodes.

· Group farming makes Sigil management easier since each player can contribute and rotate their own Sigils for back-to-back runs.

If you run low on Sigils, focus on Tree of Whispers bounties or Chaos Rifts, both of which reward new Sigils regularly.

3. Veiled Crystal Management – Balancing Your Crafting Loop

While chasing Forgotten Souls, you’ll eventually hit another bottleneck — Veiled Crystals. These are equally vital for Masterworking and upgrading items.

Fastest Ways to Get Veiled Crystals

· Farm Tormented Bosses: Summon them using your endgame materials. Salvage the Uniques they drop to gain hundreds of Veiled Crystals.

· Turn in Tree of Whispers bounties: Each completion grants 200–300 Crystals, keeping your supply healthy between dungeon sessions.

In practice, Forgotten Souls tend to accumulate faster than Veiled Crystals. Keep an eye on your crafting balance to avoid stalling your upgrades later.

4. Chaos Rifts & Helltide Integration

Although Season 10 allows you to skip Helltides, combining Chaos Rifts and Helltide activities with your main farming loop provides even better returns.

· Helltide Chests now have a higher chance of dropping Forgotten Souls and other rare materials.

· Chaos-modified Sigils occasionally open Chaos Rifts during Nightmare Dungeon runs, which also drop Souls.

· Overlap events when possible. If a Helltide starts while you’re running dungeons, take a few minutes to clear nearby Rifts for bonus Souls before returning to your route.

This method adds variety and makes farming feel less repetitive while still feeding your resource supply.

5. Bounties & Legion Events

Season 10 made Legion Events and Whisper bounties surprisingly profitable for Forgotten Soul farming.

· Legion Events spawn roughly three times per hour, each rewarding around 250 Forgotten Souls. Completing all three can net 750 Souls/hour with minimal effort.

· Tree of Whispers bounties often overlap with dungeons or world events, letting you double-dip rewards for XP and materials.

When you see a red bounty marker on a Nightmare Sigil, that dungeon is currently active for Whispers. Running it provides extra Souls, XP, and sometimes even high-rarity item drops.

6. Mercenary Den Trading

A lesser-known but reliable source of Forgotten Souls is the Mercenary Den. By exchanging Den Tokens, you can purchase Salvage Material Cages, which have a chance to drop 10–25 Forgotten Souls each.

These trades also occasionally include:

· Legendary Aspects

· High-stat weapons

· Rare crafting resources

While not your main farming method, Mercenary Den trades are excellent supplemental income. Make a habit of checking the Den after a few dungeon runs — the materials stack up over time.

FAQs – Forgotten Souls in Diablo 4

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

The best method is Nightmare Dungeon farming, specifically in Material Reserve or Horrid Material Reserve dungeons. With a full group and efficient routing, you can consistently earn 2,000–3,000 Forgotten Souls per hour. Incorporate Legion Events and Chaos Rifts between dungeon runs for even higher yields.

2. Can you get Forgotten Souls from Salvage?

Yes. Salvaging high-quality or Ancestral Legendary items can return Forgotten Souls. This makes salvaging an excellent passive source, especially if you’re drowning in excess Legendary drops from endgame content.

3. What are Forgotten Souls used for?

Forgotten Souls are primarily used at two key crafting stations:

· At the Occultist: Used to enchant Legendary or Unique items, rerolling one affix for a stronger version.

· At the Blacksmith: Used for Masterworking Ancestral or Mythic Unique gear, increasing the power of all affixes up to Rank 12.

Each Masterwork rank costs 3–15 Forgotten Souls, while resetting Masterwork progress costs 5 Souls, plus Veiled Crystals and Diablo 4 gold.

Final Thoughts

Forgotten Souls are the backbone of endgame crafting in Diablo 4 Season 10. The new farming methods—especially through Nightmare Dungeons—have made maintaining a healthy supply easier and more consistent than ever before.

By combining efficient Sigil management, group coordination, and side activities like Legions and Chaos Rifts, you can keep your materials stocked for constant upgrades and rerolls.

Whether you’re perfecting your Mythic Unique gear or just starting to masterwork your Ancestral set, these strategies ensure you’ll never run dry on one of the most important resources in Diablo 4.
