Diablo 4: How to Unlock Grigoire Boss & Rewards

The Season of Blood in Diablo 4 offered players five new endgame bosses, including Grigoire, the Galvanic Saint. These bosses provide a challenge for late game players, and drop generous rewards. To fight them, it is necessary to reach a certain World Tier and collect summoning materials, which are then sacrificed at an altar.

In this guide, Diablo 4 players can learn everything about how to summon Grigoire and Tormented Grigoire, and what rewards they will receive for defeating him – from Unique Items to Cosmetics.

Updated on August 23rd, 2024, by Abigail Angell: Season 5 has brought several new unique items to Diablo 4, changing boss loot tables. In addition, Mythic Uniques now have better chances to drop from Endgame bosses besides Duriel – something that players farming these powerful items should be aware of.

How to Summon The Echo Of Grigoire, The Galvanic Saint

Players can summon Grigoire, The Galvanic Saint (level 75) once they have:

1. Reached at least World Tier 3.
2. Collected enough of an item called Living Steel

Then, this Living Steel is sacrificed on an altar inside the Halls of the Penitent South of Ked Bardu.

How To Summon Tormented Grigoire

The Tormented version of Grigoire is a much more powerful boss (level 200), but is summoned nearly identically to the base version. Simply use some extra materials in the same location. Players will need to take 15 Living Steel and two Stygian Stones to the altar in the Halls of the Penitent, interact with the altar, and sacrifice the materials under the second window in the resulting popup.

Tips For Fighting Grigoire, The Galvanic Saint

Each endgame boss has an element that its damage primarily consists of. Grigoire’s is Lightning. Therefore, players can boost their chances of surviving the boss’ attacks by drinking an Elixir of Lightning Resistance or Socketing Topaz gems into their Jewelry.

How To Get Living Steel

Players can get this item from Tortured Gifts of Living Steel, which appear during Helltides and cost 300 Aberrant Cinders. This currency is quite easy to get since it drops from enemies that appear during the event, and therefore does not need to be farmed separately. Usually, players will encounter enemies a little stronger than the typical elite, but it still won’t be as difficult as a boss battle. Helltides run almost constantly in World Tiers 3 and 4.

If fans have trouble finding a chest, they should visit a website called D4Armory. There they will find an interactive map with the location of Living Steel chests. There is also information about the respawn timers of Bosses, Legions, and Helltides. With this information, players will be able to farm any of the game’s endgame activities.
