Since his introduction as an eternal endgame boss in the Season of Blood, we have been able to fight Grigoire, The Galvanic Saint as his Level 60 version in WT3, and Level 75 Version in WT4. Since Season 4, we are also able to take on the challenge of fighting his Level 200 Tormented version. As with other endgame bosses, Grigoire, The Galvanic Saint, has a special pool of uniques that he can drop. The Tormented Level 200 version is not only much harder, but also costs 3 times the materials to summon in addition to 2 
Stygian Stone, yet it drops 5 times the loot.

Boss Mechanics
Grigoire, The Galvanic Saint, mainly deals Lightning and Physical damage.
Stagger Bar: Like most bosses in Diablo 4, Grigoire, The Galvanic Saint, has a stagger bar. Filling this bar will stun her, allowing you to deal damage without worrying about his attacks for a few seconds.
During the fight in addition to his default attacks, Grigoire, The Galvanic Saint, has a few mechanics to look out for:
- Upon Summoning him, the ground will crackle with electricity; make sure to not be standing in it when it discharges, it follows a simple pattern, starting from the outside, and working its way into the center where he will land. He will repeat this starting at around 60% HP.
- Mace Slam: He will slam his mace into the ground, causing red electrified circles to appear on the floor, make sure to be out of them when the lightning strikes them.
- Mace Swing: When he attacks with his mace, it will release sparking projectiles which will linger around the room.
- Summon Adds:
- Knights: Grigoire, The Galvanic Saint, will summon a group of knights around the player to quickly surround and overwhelm them. Use AoE to clear them out ASAP before you get overwhelmed.
- Pylons: Watch out for connected pylons that will have a lightning bolt between them or will electrify the ground, like when he was first summoned.
