Living Steel is one of the most coveted crafting materials in Diablo 4, particularly for endgame players seeking to challenge powerful bosses and craft high-end gear. This rare resource is essential for summoning Grigoire, The Galvanic Saint—one of the Tormented Uber Bosses—and is key to progressing in the Seasonal Boss Ladder. With the introduction of Helltide mechanics and boss-targeted loot, understanding how to Diablo IV Items efficiently farm Living Steel can make a huge difference in your progression and power scaling.
In this article, we’ll break down everything you need to know about Living Steel in Diablo 4: what it is, how to use it, where to farm it, and the most efficient strategies to get the most value during your Helltide runs.
What is Living Steel in Diablo 4?
Living Steel is a rare crafting material that only drops from Tortured Gift of Living Steel Chests, which are exclusive to Helltide Events. It plays a crucial role in:
Summoning Grigoire, The Galvanic Saint (a boss needed to farm specific Unique and Mythic Unique items).
Crafting Uber Boss Summoning Materials.
Completing seasonal challenges or boss-related objectives.
Each attempt at summoning Grigoire requires a specific amount of Living Steel, and players looking to challenge the Tormented version of Grigoire at World Tier 4 will need even more.
How to Use Living Steel
Summoning Grigoire
To summon Grigoire, The Galvanic Saint, you need to visit the Hall of the Penitent, located in the Dry Steppes. Grigoire requires:
5 Living Steel for the standard World Tier 4 version.
10 Living Steel for the Tormented Grigoire encounter (used to target farm Mythic Uniques in high-end content).
You must also bring Abstruse Sigils (or Summoning Materials obtained from Whispers and World Bosses) to complete the ritual at the Bloodied Altar.
Once summoned, Grigoire can drop class-specific Uniques and seasonal crafting materials tied to the current rotation. He also has a chance to buy Diablo IV Gold drop Scattered Prisms, Forgotten Souls, and Greater Affix gear on Tormented difficulty.
