Summoning Requirements & Location
In order to summon Grigoire, collect Living Steel from any chest during a Helltide. They are primarily farmed in the Tortured Gift of Mysteries chests, which require 250 Aberrant Cinders to open. You receive 14 Living Steel in Torment 4.
Once you have collected 12x Living Steel, you can travel to Grigoire's area to summon him.
Before heading out consider a quick stop at the Alchemist to pick up a Elixir of Lightning Resistance II to help counter his Lightning abilities.
Health Bar & Stagger
Each Boss's health bar has multiple breakpoints. Once a breakpoint is reached, the red arrow flips up and turn grey. This indicates that you are in the next phase of the fight, while also dropping multiple healing vials. Each phase is more challenging than the last.
Stagger Bar Mechanic
Immediately beneath the health bar is a stagger bar, this slowly fills when Crowd Control (CC) is dealt. Once full, the Boss is rendered helpless for a short window of time. Use this opportunity to unleash as much hell as you possibly can.
Boss Mechanics and Strategy
Pay attention to the attacks used by Grigoire, The Galvanic Saint! The following section guides you through the boss's most dangerous abilities.
Grigoire's Abilities
Initially Grigoire attacks you directly, but as the fight progresses he activates electrified pylons around the room, and summons help. Being hit by these mechanics gives you a stacking Tormented debuff that increases your damage taken, so avoid them at all costs!
- Shocking Entry - The very act of summoning Grigoire charges the room with electricity.
- Watch for and avoid the electrified tiles as the boss appears.
- Spark Strike - Whenever he attacks with his massive mace, Grigoire releases several sparks which float around the room dealing Lightning damage.
- Move behind the boss to evade the attack and resulting sparks.
- It's difficult to completely avoid damage from this attack, but it doesn't hit very hard.
- Empowered Spark Strike - This works exactly like the regular version, but has a wider radius and knocks the player back if it connects.
- Position yourself so you aren't knocked into any of the environmental hazards.
- Thunderous Blow - Grigoire slams his mace into the ground creating several electrified reverberations. After a short delay, Lightning strikes each location.
- As the red circles appear to telegraph the mechanic move away from them.
- Summon Knights Penitent - After losing some health, Grigoire begins summoning Knights Penitent to aid him in combat. They will appear in a ring surrounding the player then quickly converge.
- Use AoE skills to dispatch them quickly, remember to keep an eye on the boss as you do.
Environmental Hazards
After 80% health Grigoire begins to activate environmental hazards around the room.
- Charged Pylons - Pylons appear around the room and become charged with energy, damaging players which pass through them.
- As he begins to charge the pylons, position yourself near the center of the room so you have more options to safely move.
- By themselves these are easy to avoid, however you need to position yourself carefully so Grigoire's attacks don't knock you into the beam.
- Alternatively, use Unstoppable to prevent yourself from being knocked back.
Galvanic Ascendance
- Starting at 60% Grigoire begins using his ultimate move! He teleports away, then begins to channel massive amounts of electricity into the room, this not only activates the Pylons but charges floor tiles which light up in sequence before he crashes back into the arena.- The Pylons restrict your movement, position near the center of the room and have your Evade or a movement skill ready.
- The room has 9 total tiles.
- 7 will be electrified.
- 2 are safe.
- Watch the pattern closely and move to one of the 2 safe tiles.
