How to Fight Grigoire, The Galvanic Saint in Diablo 4

Diablo 4

Grigoire, The Galvanic Saint is an optional boss you can seek out and defeat in Diablo 4. If you’re wanting to complete your season journey or face off against the powerful Uber Duriel, however, chances are you’ll have to face off against him at some point. So, how do you fight Grigoire, The Galvanic Saint in Diablo 4?

To fight against Grigoire, The Galvanic Saint in Diablo 4, you first need to be on World Tier 3 or 4. If you’ve not unlocked World Tier 3 yet, grow stronger and then complete the Capstone dungeon in Kyovashad. Once you are on World Tier 3 or higher, however, you can fight against Grigoire, The Galvanic Saint by heading to the Hall of the Penitent, which is found in Dry Steppes, south of Ked Bardu. Although you also need some Living Steel to summon him.

On World Tier 3, just 2 pieces of Living Steel are required to summon Grigoire, The Galvanic Saint. On World Tier 4, however, 5 pieces are required. It’s easier to acquire Living Steel on World Tier 4, however, as you’ll get some every time you open a chest during a Helltide. On World Tier 3, the only way to acquire Living Steel is to open a Tortured Chest of Living Steel during a Helltide, which at the moment of writing costs 275 cinders. At least the chests appear on the map, though, making them easy to find.

When you have the required amount of Living Steel to summon Grigoire; The Galvanic Saint, simply head to the Hall of the Penitent and after fighting through a small number of enemies you should some across an altar. Place the Living Steel and choose to summon Grigoire to start the fight. To survive, you’re going to want a lot of lightning resistance, so bear that in mind. Emerge victorious, and aside from getting valuable loot there’s also a chance you’ll get a Shard of Agony, which is required to summon one of Diablo 4’s strongest bosses, Echo of Duriel.
