Gruz Mother is a Boss in Hollow Knight. Bosses are special Enemies that feature their own arena, a large amount of health, and a variety of unique moves and abilities. You will need to perform multiple attacks such as using The Nail and Nail Arts along with the Spells and Abilities in order to defeat them. Some bosses are capable of entering into a state of stagger after landing a number of attacks on them.

As soon as you encounter a boss, its name will appear on the screen, the music will change into a boss battle theme, and usually,  paths connecting the arena will close or will be blocked leaving you no choice but to face these devastating and unique foes.


Mature gruzzer that carries its young in its belly. Attacks by hurling its huge body around.

Bizarrely, this monster does not lay eggs but instead carries its young inside of its fat stomach. This strange practice seems to exhaust the creature, making it sleepy and vulnerable. Take advantage!

Gruz Mother Strategies

Strategy Writeup

The Gruz Mother is an optional boss. You can first encounter her at the Forgotten Crossroads sleeping in front of a locked gate, striking her with The Nail will cause her to wake up and initiate the boss battle. The first phase of the battle is all about facing the mother herself, she will always fly around the area as her way of traversing and avoiding any attacks and will follow up with two kinds of attacks. The first attack is a charge attack where she flies up high and quickly charges towards The Knight, the second attack is the one you need to look out for since it is a slam attack where she will slam her body up and down towards The Knight until she reaches a wall - it is dangerous to stay in one place or if you react late since the attack is fast, covers most of the arena and will only stop until hitting the wall, so it is recommended to keep your distance and only attack or recover health once she has reached the end.

Once you've dealt enough damage, she will fall to the ground, showing that there is something moving inside her. Phase 2 will begin after a period of time where the Gruz Mother's corpse will explode and Gruzzers will emerge. A few strikes with The Nail will eliminate these creatures and killing the last one will mark the completion of the boss battle.

In the Colosseum of Fools, the Trial of the Warrior, two Gruz Mothers will be fought at once. Their attacks remain the same, the only difference is they will not spawn Gruzzers upon death.

Since she is an optional boss and has low health, obtaining certain Spells and Abilities first would be wise. If you acquire the Mothwing Cloak ability, you will be able to dodge easily, especially during the body slam attack. And second is acquiring and using the Vengeful Spirit spell, this will allow you to inflict damage on the boss even though you are far away from each other.


Attacks & Counters

Attack Counter
Phase 1
Mother's Charge The first thing to take note of is that the Gruz Mother will fly all throughout the match. Its first attack is a charge attack where she will fly high into the air and follows up with a charge attack towards The Knight's position and slams into the ground - this attack inflicts damage upon contact.
Slam Attack In conjunction with flying around the arena, the Gruz Mother's second attack is a slam attack where she slams her body violently onto the ceiling and floor while slowly moving towards The Knight. She will only stop this attack once she reaches the end of the arena.
Phase 2
Gruzzers After landing the last strike, the Gruz Mother will fall to the ground on her back, showing her belly that seems to be moving. After a brief moment, the corpse of the Gruz Mother will explode and 7-8 Gruzzers will emerge in the arena. The Gruzzers will not target The Knight but will just fly around, bounce off walls and will inflict damage upon contact.



Gruz Mother Lore

The mother of all Gruzzers. They are a unique creature where instead of laying eggs, they keep the young ones inside of their stomach and releases them once they are strong enough. There isn't any other information on how they fit into Hallownest but are only considered to be a dangerous yet exhausted creature.
