Bestiary
Master of the Grimm Troupe.

Through dream I travel, at lantern's call

To consume the flames of a kingdom's fall

- Grimm


After the Grimm Troupe has been summoned, Grimm can be found inside the large building at the center of their setup to the left of Dirtmouth. Inside, after talking to him, he gives the Knight the Grimmchild charm. After collecting three flames, he upgrades the charm to the next level, and after collecting three more, the Knight must fight Grimm.

Behaviour and Tactics

Before the battle, Grimm will bow. If the Knight hits him while bowing, Grimm will screech at the Knight and will counter attack with the Flamespawner Attack.

If Grimm teleports on the ground too close to the Knight, he will Skitter away on all fours before resuming his attack. It is rare but possible that Grimm will begin a telegraph for one type of ground attack, Skitter away, and then do a different ground attack.

  • Fire Bats: Grimm will open his cloak, sending three Fire Bats at the Knight. The Fire Bats start at the level of the Knight's head and poorly track the Knight's movement. Grimm remains stationary during this attack. Each Fire Bat's entrance is announced with a gout of flame coming from Grimm and reaching the top of the arena. If the Knight gets within arm's length of Grimm before he sends out all three Fire Bats, he will teleport to another part of the arena and send one last Fire Bat. This Fire Bat cannot be interrupted. This means that it's possible for Grimm to send out only one Fire Bat.
  • Dive Dash: Grimm will wrap himself in his cloak until he resembles a drill and dive towards the Knight. Then he lands and follows up with a dash towards the Knight's direction using his arm wrapped in his cloak like a lance. Grimm tracks where the Knight was near the start of the dive and the dive can traverse the entire arena.
  • Dash Uppercut: Grimm will dash across the arena with a large swipe directly before launching into the air with an uppercut. At the apex of the uppercut, he disappears and rains five fireballs on the arena. The five fireballs rain down on the arena in set parabolas.
  • Cloak Spikes: Grimm will send his cloak into the ground, causing large twisted cloak spikes to jut up from the floor. The spikes reach to the top of the arena but there are large enough gaps between them to stay safe. The spikes are not dangerous until they are at their tallest. The spikes persist for about half a second.
  • Flamespawner: Grimm surrounds himself with his cloak and puffs out and spews tiny fireballs all over the arena. This attack occurs when Grimm's health reaches 75%, 50%, or 25%. This attack always occurs from the center of the arena. The fireballs travel in five general directions. Fireballs tend to come at the Knight in sets of two, resulting in essentially a jumping puzzle. Grimm will stay in this form for nearly nine seconds. While he's in this mode, Grimm is immune to Nail damage but still takes damage from everything else.
Stagger Values
Description: Grimm's stagger is unique as he will disperse into a swarm of bats resembling the Grimmchild that fly around for 3.5s. Grimm will appear in this swarm as the bat with the red eyes. Attacking him will not end the stagger but only a maximum of 50 damage can be done regardless. After the stagger ends the bats collect and reform back into Grimm.

Hollow Knight Boss Discussion - Troupe Master Grimm

Hollow Knight Boss Discussion - Troupe Master Grimm

Grimm is one of the faster bosses in the game, and his health scales with nail upgrades, making him a tough foe regardless of experience or progress.

Because Grimm moves by way of teleportation and rarely stays in one place for long, from an offensive perspective, it's important to deal as much damage to Grimm in the shortest time possible.

Each spell has its use against Grimm. Vengeful Spirit is useful to use during the Cloak Spikes, Pufferfish Attacks and Fire Bats Attack. Desolate Dive is a great way to dodge the Dive Dash Attack. It's best to use it almost as soon as the player sees Grimm preparing the Dive Dash Attack because Grimm will land in the middle of it. Howling Wraiths can be useful during a Pufferfish Attack right before the fireballs start to spawn and during a Cloak Spikes Attack since Grimm is taller than the Knight.

The Nail Arts Great Slash and Dash Slash are also useful, providing 2.5x Nail damage and good range for damaging Grimm and staying safe (especially during Cloak Spikes, Dash Uppercut, and Fire Bats Attacks).

Use the Shade Cloak to dash through both of his Dash attacks (Dive Dash and Dash Uppercut). The player can also damage Grimm this way if they have Sharp Shadow.

Standing directly next to where Grimm explodes into fire when he uses Dash uppercut is a good way to avoid all 5 projectiles as they spread in a cone pattern, this also gives healing opportunity especially with Quick Focus.

During the Cloak Spikes attack, The player can use the time to heal. This is easier to do with Quick Focus.

Shape of Unn is a fantastic way to heal against Grimm. The charm lowers the Knight's hitbox so players can heal safely during a Fire Bats Attack. If combined with Quick Focus, the player can run and heal from Grimm during a Dash Uppercut Attack too. It can also be used to heal and position at the same time during the Cloak Spikes attack.

If the Knight stays near the the right/left side of the screen and light tap jumps, they can mostly avoid the flames during Grimm's Flamespawner Attack.

Double jump and dash over the Fire Bats, putting the Knight in range to attack.

Dialogue

General

First encounter

So, it was you who called us.

Well met, my friend. Well met. I am Grimm, master of this troupe. The lantern has been lit, and your summons heeded. A fine stage you choose, this kingdom fallowed by worm and root, perfect earth upon which our Ritual shall take place. And you, my friend. Your own part is far from over.

As the lantern flared your role was cast, our compact written in scarlet fire. Eager we are to see you commence, but first, some illumination is required.

Across these lands my kin now spread, harvesting that essence peculiar to my... breed, the flame in dream. Seek my kin; claim their flame and return it to me. Together, marvels shall be achieved. But don't fret small one. For this task you won't travel alone. My child shall guide you to the flame and gather within itself that burning essence. Like you, the child plays key role in this task. Only with it by your side will the flame, and my kin, reveal themselves to you.


Returning with all flames first time

I can feel it. The warmth of the flame you've gathered together.

A masterful opening act. The air hums with excitement. Dear child, you've done so well. Let your fire burn even brighter!

Beautiful, yes. The child has grown, from idle youth to deadly companion. About these dangerous lands, its aid will no doubt be welcome. Just don't neglect our dance, for it too continues! Keep hunting that scattered, scarlet essence. When the child is filled with flame once more, return to the stage and the performance will begin.


Before battle

Wonderful. Wonderful! My kin arrive and the time has come.
This searing fire... It carries well the Ritual's promise.

Dance with me, my friend. The crowd awaits. Show them you are worthy of a starring role!


After defeat

Bravo, my friend. Hear how the crowd adores you! They've not seen such a show in a long time.

Look here! How our child has grown, nourished and strengthened by the heat of our passionate dance! The two of you will feature in many tragedies and triumphs together, I'm sure.

And so our great Ritual nears it end. Will you continue to harvest the flame, even though now you surely see the path it illuminates for us? Our scarlet eyes will watch you keenly... friend.

Go out into the darkness. Harvest the last lingering embers of this Kingdom. Then return to me and we will complete our dance.

Trivia

GG grimm bow0006

Grimm bowing to Godmaster Icon The Godseeker

  • Grimm will bow to the Knight before the start of the fight, if struck when bowing he will screech and start the Flamespawner attack.
  • The Grimmchild charm is required every time to start the battle.
  • The fight with Grimm is accompanied by audio cues for some events:
    • When Grimm performs the Flamespawner attack, the theme gets more dramatic by adding chorus to background.
    • The Grimmkin audience watching give ovation to Grimm every time he performs the Flamespawner attack or reforms after stagger.
    • When Grimm reforms after stagger, he is accompanied with a drumroll.
  • There is a secret area in Grimm's tent above the arena where the empty masks of the audience can be found. It can be accessed by wall climbing through a false ceiling to the right of the arena, second arch.
    • When using a spell in this secret room some sort of barrier appears which may possibly be related to a Seal of Binding.
  • There is some speculation as to what species of bug Grimm is supposed to be:
    • It is possible that he is a bat due to the fact that he sleeps upside down and generally resembles a vampire.
    • In a response in one of their Hollow Knight streams Team Cherry has stated:
Grimm Shield
Can you confirm Grimm was inspired by Dracula from Castlevania?
Ari: “I don’t think- I mean Grimm obviously has a lot of Dracula-like qualities. But he also has other elements.”

William: “He’s like a mix of a lot of things.”

Ari: “Yeah, he has this kind of circus master quality, and-”

William: “Halloween-y.. He’s spooky.”
  • Lifeblood Icon A red barrier will appear over Grimm when trying to enter the Nightmare King Grimm fight without Grimmchild equipped.
  • Godmaster Icon Even in Godhome, it is not possible to fight him with Grimmchild. If equipped, it will not be present for the duration of the fight. The same is true for Nightmare King Grimm.
