Harness the Power of Shards, Summon Duriel, and Conquer Diablo 4’s Endgame

In the post-story realm of Diablo 4, facing formidable bosses is a key aspect of progression, and the elusive Shards of Agony play a pivotal role. This guide explores acquiring, summoning, and utilizing Shards of Agony in Diablo 4, preparing players for challenges.
Locating Shards of Agony in Diablo 4

In Diablo 4, players obtain Shards of Agony by defeating Grigoire, The Galvanic Saint, with critical aspects to consider:
- Boss Encounter: Engage Grigoire in the Hall of the Penitent, Dindai Flats, specifically at World Tier 4.
- Tier 4 Requirement: Exclusive rewards, including Shards of Agony, are available solely at the highest difficulty level.
- Singular Reward: Shards of Agony are granted only to the player initiating the boss summoning altar, crucial to note when engaging in group battles.
- Retry Possibility: In cases of non-receipt, there’s a slight chance of missing Shards; a retry might be necessary.
Summoning Grigoire – The Galvanic Saint
To initiate Grigoire’s summoning at World Tier 4, deposit 5 Living Steel atop the altar in the Hall of the Penitent. Acquire Living Steel from the Tortured Gifts of Living Steel chests during Helltide events:
- Helltide Events: Occur every 75 minutes in random locations, lasting 60 minutes.
- Living Steel Yield: Each chest rewards 3 Living Steel; 5 are required for the summon.
- Aberrant Cinders Cost: Each chest opening demands 300 Aberrant Cinders.
Upon gathering 5 Living Steel, set them upon the altar to summon Grigoire. Ensure preparation for combat, as Lightning-based protection and equipment are pivotal to success against this level 75 boss. Familiarizing yourself with Grigoire’s attack patterns aids in avoiding substantial damage.
How To Use Shards of Agony

The primary utility of Shards of Agony is in summoning Duriel. Here’s how:
- Requirements: Two Shards of Agony and two Mucus-Slick Eggs.
- Altar Location: Discover the altar within the Gaping Crevasse dungeon in Kehjistan’s southernmost region.
- Level 100 Boss Fight: Face Duriel in an intense battle offering remarkable rewards, including Uber Unique items.
By mastering these steps, players can command Shards of Agony, challenge formidable bosses, and delve into Diablo 4’s exhilarating endgame.
