Flukmarm 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.


An insatiable breeder. Has populated the Waterways with its kind. Its insides double as a nest for young Flukefeys.

The desire to breed, to leave behind a memory of ourselves in the shape of a child... it seems to be etched deep into the heart of every living creature. I too have felt the pull of that base instinct.

Flukmarm Strategies

Strategy Writeup

The Flukemarm is an optional boss fight. She can be found in the Royal Waterways hanging in the middle of the arena. You will find her sleeping and passive. The battle starts once you strike her with The Nail.

The Flukemarm has only one attack, and that is to spawn Flukefeys that will chase and attack you once they come out. Keep in mind that she always spawns two Flukefeys every 3-4 seconds, up to a maximum of 6 Flukefeys.

It is recommended to get rid of the Flukefeys first. After that, get on top of the Flukemarm. Jump onto her and perform a few downward strikes before landing back onto a platform. And finally, make sure you do not fall into the water. You will not be able to attack, making you open for the Flukefeys.

Charms: Since this is an optional boss, you can try to obtain the following recommended charms first that can help you win this battle. Thorns of Agony/Defender's Crest: either of these can be helpful in dealing with the Flukefeys. Grubsong: since you will frequently take damage, having this charm equipped will help you be consistent with using your spells. Speaking of Spells, Quick Focus is useful if you need a quicker rate of recovering your health.

Spells and Abilities: Vengeful Spirit can be used on the boss itself while Howling Wraiths might give you a bit of breathing room from the Flukefeys. If you're going down this route, have the Shaman Stone and Spell Twister charms equipped in order to increase the overall effects of your spells.

One last thing to remember is to make sure you upgrade The Nail by speaking to the Nailsmith. Similarly to The Collector fight, this one will go much easier if you can kill the Flukefeys in one hit.
