How to Summon Grigoire in Diablo 4: Locations, Materials & Rewards
Summoning Grigoire in Diablo 4 requires collecting a resource called Living Steel, which players obtain by participating in Helltide events. To summon Grigoire, one must deposit 2 Living Steel in World Tier 3 or 5 Living Steel in World Tier 4 at the Light-Touched Altar located in the Hall of the Penitent in Dry Steppes. This process unlocks the fight against Grigoire, a key boss in the game’s seasonal content.
Living Steel is found inside special chests called Tortured Gift of Living Steel, which appear only during active Helltides. Opening these chests costs Aberrant Cinders, another currency earned through activities within the Helltide. The boss fight is not just a challenge; it also provides essential rewards, including Shards of Agony needed to summon other powerful bosses.
Players looking to engage Grigoire will benefit from understanding these summoning mechanics and preparation steps, as they streamline access to this important boss encounter and its valuable loot.

Summoning Grigoire: Requirements and Procedure
Summoning Grigoire, The Galvanic Saint, requires navigating specific locations, preparing the necessary materials, and understanding the interplay between World Tier settings and summoning costs. This process involves engaging with Helltide events to gather Living Steel, which is essential to activate the summoning ritual.
Grigoire Location in Hall of the Penitent
Grigoire is summoned inside the Hall of the Penitent, a dungeon situated in the Dry Steppes region, south of Ked Bardu. Within this dungeon lies the Chamber of Penitence, where the summoning takes place.
The player must proceed through the Hall until reaching a Light-Touched Altar in the Chamber of Penitence. This altar is the focal point for the summoning ritual. The Hall of the Penitent serves as a fixed location, so traveling here is straightforward once the Dry Steppes are accessed.
The dungeon housing Grigoire is distinct from other areas, featuring a focused environment designed specifically for this boss encounter, which ensures players can prepare accordingly before initiating the fight.
World Tier and Difficulty Settings
World Tier settings directly affect the amount of Living Steel needed to summon Grigoire. In World Tier 3, the summoning cost is 2 Living Steel. For World Tier 4, the requirement increases to 5 Living Steel.
Higher tiers reflect greater difficulty but also yield better rewards. Players must unlock World Tier 3 to participate in the Helltide events required for obtaining Living Steel.
Additionally, the Torment difficulty level influences monster strength and loot quality during Helltide events, making the farming process more challenging but more rewarding.
How to Obtain Living Steel
Living Steel is exclusively obtained from Tortured Gift of Living Steel chests, which spawn during Helltide events in active regions like Dry Steppes, Hawezar, Fractured Peaks, and Scosglen.
Opening these chests costs 300 Aberrant Cinders, a unique currency gained by defeating monsters, completing objectives, and interacting with world elements during a Helltide.
Players must defeat an elite enemy named He-Grins-Wide-and-Waits guarding each chest to claim their rewards. In World Tier 3, each chest drops 1 Living Steel, while in World Tier 4, the chest provides 3 Living Steel.
Aberrant Cinders do not carry over if unused prior to the Helltide’s expiration, and half are lost upon death, making efficient farming essential.
Using the Light-Touched Altar to Summon Grigoire
Upon collecting the required Living Steel, players travel back to the Hall of the Penitent and enter the Chamber of Penitence. Interacting with the Light-Touched Altar allows them to deposit the Living Steel.
After placing the necessary amount—either 2 or 5 depending on World Tier—the player can initiate the summoning by pressing the Summon button.
This triggers the appearance of Grigoire, who must be defeated to earn unique loot including rare drops and potential boss-specific rewards.
The altar interaction is a singular and clear action point, marking the transition from preparation to combat.
Boss Mechanics, Strategies, and Rewards
Grigoire, the Galvanic Saint, is a lair boss with distinct mechanics that challenge players with lightning and physical damage. Combat strategies focus on managing arena hazards and enemy summons. Preparing defensively and efficiently using resources increases survival chances. The boss offers unique loot rewarding players for their efforts, including items essential for summoning Duriel.
Fighting Grigoire: Boss Abilities and Arena Hazards
Grigoire’s attacks combine lightning and physical damage. He uses a stagger bar that, when filled, stuns him briefly, opening a damage window. Key abilities include the Mace Slam, marked by red electrified circles that quickly detonate, and Mace Swing, which releases lingering spark projectiles. Staying mobile is critical to avoid continuous damage.
The arena features electrified pylons connected by lightning arcs that damage anyone crossing them. Grigoire spawns knights that attempt to corner players, so employing area-of-effect (AoE) skills to clear these minions fast is important. His initial summoning creates a shockwave in a grid pattern, and players must dodge out of the electrified squares as the effect reaches the center.
Preparation: Lightning Resistance and Useful Items
High lightning resistance is vital due to Grigoire’s electric attacks. Players should maximize this resistance through gear and consumables. The Elixir of Lightning Resistance II boosts maximum lightning resistance and enhances survivability.
Players must bring a build with strong single-target damage and good survivability. Defensive buffs, healing items, and mobility skills improve the ability to avoid or mitigate damage. Bringing reliable AoE abilities helps against summoned knights and pylons. Preparation also includes collecting twelve Tortured Gifts of Living Steel, which are required to loot the chest after defeating Grigoire.
Loot Table and Unique Drops
Grigoire’s loot table contains boss-specific unique drops and general uniques. The first unique item each run is guaranteed from his unique pool, which can include high-tier and mythic uniques. Additional uniques have a 50% chance to come from the general unique pool.
Loot can include valuable items like Penitent Greaves and the Demonbinder Mount Armor cosmetic. Group play increases the chance of extra unique drops by 33% per additional member. Defeating Grigoire also rewards Shard of Agony, a required material for summoning Duriel, and Stygian Stone, which is used to craft lair keys for other boss encounters.
Using Shard of Agony for Summoning Duriel
The Shard of Agony dropped by Grigoire is a key component to summon Duriel, another powerful lair boss. Players need to collect this shard along with additional components obtained from other sources to initiate the Duriel fight.
This shard emphasizes the importance of farming Grigoire in the Season of Blood and other challenging endgame content. Efficiently farming and acquiring Shard of Agony speeds up access to Duriel, which offers distinct loot and further progression opportunities within Diablo 4’s lair boss system.
