How To Get Nebulous Extract in Diablo 4 Season 9

Diablo 4 continues to empower players with unparalleled customization, especially for spellcasters. With a vast array of spells to choose from, each season introduces new ways to enhance your build. Season 9 brings the Nebulous Extract, a powerful Infusion that elevates Shadow and Corrupting damage builds to new heights.
If you're looking to maximize your spell damage and debuff potential, this guide will walk you through how to obtain the Nebulous Extract Infusion in Diablo 4 Season 9.

What Is Nebulous Extract in Diablo 4?

Infusions in Diablo 4 modify spell behavior, adding unique effects that can drastically improve combat efficiency. The Nebulous Extract is one of the most sought-after Infusions in Season 9 due to its incredible synergy with Shadow and Corrupting damage builds.

Nebulous Extract Effects:

• Converts Catalyst-type spells to deal Shadow/Corrupting damage.
• Debuffs enemies, reducing their damage output by 5.5% for 7 seconds.
• Scales with your highest Damage Type Bonus, ensuring optimal damage output.

This combination of high burst damage and enemy debuffs makes Nebulous Extract a must-have for spellcasters.

How to Unlock Nebulous Extract in Diablo 4 Season 9

To obtain this powerful Infusion, you must complete The Unseeable Demands Their Gaze, a quest introduced in Season 9. Here’s a step-by-step breakdown:

Step 1: Start the Questline

• After completing the "Reopening the Wound" quest, head to Cerrigar.
• Speak to Davish, who will inform you that Bryona has gone missing.
• He tasks you with finding her and directs you toward the Horadric Vault.

Step 2: Locate Bryona in the Horadric Vault

• Travel to the Horadric Vault and speak with Bryona.
• She will ask you to collect Donan’s drafts scattered around the area.

Step 3: Enter a Nightmare Dungeon

Step 4: Retrieve the Blood Relic
