Silksong bosses locations map
Here's a quick overview map of all the boss locations in Silksong. Thank you to Map Genie for both creating this map and letting us use it.
Moss Mother
Location: Moss Grotto (in the Ruined Chapel).
Moss Mother is very much Silksong's tutorial boss and serves this purpose well. Her fight demonstrates the importance of dodging attacks, especially when it comes to jumping over your foe, and getting in one singular hit before retreating. Her primary attack is flying down towards Hornet with her stringer outstretched. She will hover in the air afterwards, giving you the chance to hit her. Just don't get hit by the stringer!
As the fight progresses, Moss Mother will cause rocks to fall from the ceiling and summon Moss Grubs. Keep an eye out for dust falling from the ceiling - this will tell you when and where these extra obstacles will appear.
Check out our Moss Grotto walkthrough for more details on defeating the Moss Mother.

Bell Beast
Location: The Marrow (north-east of the entrance). Starting the battle requires the Silkspear ability.
The Bell Beast begins the fight with two primary attacks - dashing forward before swiping its tail and jumping over Hornet. As the fight progresses, it also emerges from the ground and tosses two bells at you. Thankfully, these can be easily dodged by putting some distance between yourself and the Bell Beast. Finally, towards the end of the fight, it will cause bells to fall from the ceiling.
When it comes to defeating the Bell Beast, the best time to strike is when it's landing from a jump. It will be vulnerable during these few vital seconds and perfect for hitting. You can also try pogoing it during its dashing attack. Just try to avoid falling down onto the beast after a successful hit.

Lace (Deep Docks)
Location: Deep Docks (before entrance to Far Fields). Starting the battle requires the Swift Step ability.
Lace is a recurring boss in Silksong and her fight in Deep Docks marks a step up in the game's difficulty. She has a range of different attacks, which I go over in full within the Lace (Deep Docks) boss strategy guide.
Keeping things brief here, it's important to note that her primary attacks are a forward sword thrust and dive attack very similar to Hornet's pogoing attack. When you reach Phase Two, she will start using an attack that causes a circle to appear. Always ensure you're outside of this circle and the attack will be avoided!
The key to defeating Lace is dodging as many of her attacks as possible, then, once she's completed one, rushing in and getting one hit in. Make sure it's one hit too as Lace can block your attacks and, if she does so too many times, she will unleash a powerful flurry attack! You focus on using either pogoing attack or carefully manoeuvring for your single hit.

Fourth Chorus
Location: Far Fields (before the area containing the Streamstress). Requires the Drifter's Cloak to start the battle.
Defeating the Fourth Chorus involves dodging its various attacks and ensuring you don't accidentally fall into the lava. Sounds simple right? Well the Fourth Chorus will cause certain parts of the platform Hornet is standing on to vanish throughout the fight. They will thankfully remain, but be prepared to do a lot of jumping.
The first is swiping horizontally with either of its lower two arms and the second is slapping downwards with either of its upper two arms. Luckily, the direction of these attacks is easy to figure out. The Fourth Chorus starts using its third attack after you've stunned it for the first time. During this attack, this large bug will cause rocks to fall from the sky.
To defeat the Fourth Chorus, you need to hit its head. For more tips, including a way to end the boss battle slightly early, check out our Fourth Chorus boss strategy.

Moorwing
Location: Greymoor (south-western corner, near entrance to Bellhart).
Moorwing is a flying boss and, like many flying bosses in gaming history, this means trouble. It has a dive attack where he'll fly right at Hornet and, even when jumping over Moorwing, you may still get hit. Though sometimes Moorwing will fly into a platform and stun itself. There's also a disc attack and slice attack - both of which can take two masks worth damage.
Defeating Moorwing involves a heavy use of Silkspear since range attacks are safer attacks. You can also try luring Moorwing into hitting the platforms and stunning itself. Though always try to avoid being directly beneath Moorwing as this could lead to an early death.
Don't worry if you're having trouble defeating Moorwing. Not only is there a cheese method for this fight, but you actually avoid it all together. Learn about both in our Moorwing boss strategy guide.

Sister Splinter
Location: Shellwood (near central elevator).
Sister Splinter may be hanging from the ceiling, but that doesn't mean she can't cause Hornet a lot of pain. She has the ability to slam down onto the ground and create thorns which will reduce the amount of free space you have. While these thorns can be destroyed by yourself or Sister Splinter, you need to be careful when dealing with them.
She starts using her most annoying attack, however, after you've stunned her for the first time. It's at this point she'll start summoning Splinterbarks and these enemy bugs will spawn until the fight is over. It's at this point where you'll have to manage defeating the Splinterbarks alongside Sister Splinter. Let yourself get overrun and the battle will be over!
Check out our Sister Splinter boss strategy guide for more in-depth knowledge on how to defeat this Silksong boss.

Widow
Location: Bellhart (northern section).
The Widow's difficulty comes from her attack speed - fast - rather than her actual attacks - simple. This means victory comes in part from learning how to fight at her speed to ensure you can one) dodge her attacks and two) get some of your own attacks in. It's also important to note that she does change some of her attack tells in Phase Two of the fight, so make sure you're paying close attention! You'll also be dodging bells again during this fight, so I hope you like doing that.
The real problem with the Widow fight, however, is that she tries to trick you. The victory sound will play and you'll drop your guard, thinking all's well and safe. But - surprise! You've just entered Phase Two and the Widow is definitely out for Hornet's blood now. Just keep dodging and getting those attacks in until you've actually defeated her.
