Diablo 4 Grigoire the Galvanic Saint Boss Guide

In this Grigoire the Galvanic Saint boss guide, we'll cover his location, how to summon both versions, and item drops.

Grigoire the Galvanic Saint was a boss introduced in Season 2. He was introduced alongside Lord Zir with the intent to broaden the list of bosses that the player could summon and flesh out ways for players to obtain unique items.

Players are also incentivized to hunt Girigore the Galvanic to loot the Shard of Agony, which is used to summon Duriel.

This guide was written by Blyndside.

Grigoire the Galvanic Saint Location

In Dry Steppes, just south of the town of Ked Bardu, there’s a region called Dindai Flats; Grigore can be found here within a dungeon known as the Halls of the Penitent.
