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

For Diablo 4 Season 9 players pursuing triple masterworked gear, the resource bottleneck presents a significant challenge. You’ll rapidly deplete your reserves of Forgotten Souls and Obducite during the enhancement process. Fortunately, recent game updates have substantially improved material acquisition rates, while community-discovered techniques provide additional efficiency boosts. This guide delivers the most optimized approach for accumulating both critical materials simultaneously, featuring a structured rotation that eliminates wasted time between activities.

Why prioritize Legion Events? Recent balancing changes have transformed these world events into exceptional resource generators. Completing one on Torment IV difficulty now provides:

• 200–250 Forgotten Souls per completion
• Substantial quantities of Veiled Crystals
• Essential components for summoning major bosses
• Consistent ancestral gear drops

Event frequency and timing:
Legion Events activate every 25 minutes across Sanctuary, with each requiring approximately 3 minutes to finish. This translates to potential earnings of 500+ Forgotten Souls hourly when properly scheduled.

Optimal tracking methodology:
Utilize helltides.com to monitor upcoming Legion spawns with precision. Establish notification systems to ensure you never miss these lucrative opportunities.

During the intervals between Legion Events, focus your efforts on Obducite acquisition. Below is a prioritized list of methods based on time efficiency:

✅ Elite Strategy: Lair Boss Teleportation Technique

Execution steps:

1. Initiate a Nightmare Dungeon containing Horadric Strongroom opportunities (Uldur’s Cave represents an ideal candidate).
2. Bypass traditional dungeon clearing by teleporting directly to various Lair Boss locations:
• Gregoire’s domain
• The Hanged Man’s Hall
• Urivar’s lair
• Varshan’s territory
• Lord Zir’s castle
• Harbinger of Hatred’s arena
3. When encountering a location marked by purple flame indicators, this signifies an active Horadric Strongroom. Complete these for substantial Obducite returns (typically 2,000–2,500 units within minutes).
4. Cycle through the rotation and return to initial locations after completing the circuit—Strongrooms reset upon completion.

Strategic advantage:
This methodology eliminates lengthy dungeon completions while directly targeting high-yield Obducite sources, dramatically reducing grind time.

⚔️ Secondary Option: Tribute of Refinement Expeditions

• Requires acquisition of Tribute of Refinement tokens (obtainable from Lair Boss encounters or Whisper completions)
• Generates approximately 2,000 Obducite within 2–3 minutes
• Enhanced efficiency through cooperative play or party finder utilization for rapid consecutive runs

🔥 Tertiary Approach: Infernal Hordes Optimization

• Represents the optimal equilibrium between Obducite acquisition and time investment
• Completes in 10 minutes while providing 2,000–3,000+ Obducite
• Provides reliable sources of Burning Aether
• Avoid 10-wave variants unless specifically targeting Aether, as they require 13 minutes

⚠️ Least Efficient: Nightmare Dungeon Material Reserves

• Horadric Chests possibility to yield 15 Forgotten Souls alongside gold resources
• Unreliable spawn patterns and scattered distribution
• Most effectively incorporated during glyph leveling sessions or as supplementary activities

Implement this sophisticated rotation to maximize your farming productivity:

1. Consult helltides.com – document the remaining time until subsequent Legion Event.
2. With 15–20 minute intervals available:
• Commence the Lair Boss rotation targeting Horadric Strongrooms.
• Incorporate Whisper completions or Tribute of Refinement runs if tokens are available.
3. Upon Legion Event initiation:
• Immediately transition activities, complete for approximately 250 Forgotten Souls.
4. Repeat the complete cycle continuously.

This systematic approach guarantees continuous productive engagement, ensuring you’re consistently acquiring either Forgotten Souls or Obducite while building the necessary reserves for Masterworking progression.

Avoid these critical errors:

• Missing Legion Event start times due to poor tracking
• Wasting time on inefficient Obducite sources when better options exist
• Failing to coordinate activities with available time windows
• Overlooking party opportunities for Tribute runs
• Attempting to farm multiple materials simultaneously rather than focusing

Advanced optimization techniques:

• Pre-position characters near upcoming Legion Event locations during Obducite farming
• Utilize multiple characters to bypass instance cooldowns when available
• Schedule farming sessions around peak Legion Event frequency periods
• Combine material farming with other progression goals like glyph experience

Time management recommendations:

• 15+ minutes: Lair Boss teleport method
• 5-14 minutes: Tribute of Refinement runs
• Under 5 minutes: Inventory management and preparation

Achieving triple Masterworking status demands substantial Obducite reserves alongside significant Forgotten Soul stockpiles. The essential strategy involves synchronizing your farming activities with the predictable 25-minute Legion cycle while incorporating the most time-efficient Obducite sources during waiting periods.

Execute intelligently. Accumulate efficiently—Masterwork progression without excessive grind.
