As you delve into the enchanting yet treacherous Shellwood in Hollow Knight: Silksong, you’re bound to encounter a host of challenges designed to test your endurance. The game’s tricky flower-themed platforming and the constant threat from common enemies add layers of difficulty, especially if you let your guard down.
Among the notable foes lies a hidden boss that truly encapsulates the importance of patience — the Sister Splinter. This formidable opponent awaits you in the heights of Shellwood, where defeating her is paramount if you aim to preserve your Rosaries, given that Hornet’s silk cocoon becomes ensnared within the battleground.
If you’re seeking guidance on how to conquer Sister Splinter, you’ve come to the right place! This comprehensive guide will equip you with the strategies you need to emerge victorious. Let’s dive in!
Locating Sister Splinter and Preparation Tips

The Sister Splinter awaits you at the topmost region of Shellwood, just above the central area and near the highest entrance to Bellhart. To access this location, activate the lift leading to the main Bench. This setup conveniently facilitates repeated attempts to defeat the boss, as it creates a straightforward path between the bench and the arena.
Starting from the Bench, take the lift up and veer to the right. Continue along the path until you reach a fork: you can either ascend towards Bellhart or traverse left over some platforms. Opt for the latter route, bouncing off the white flowers as you leap leftward.
You’ll recognize the boss arena by the appearance of spiked vines blocking your exit— a clear indicator that Sister Splinter is ready to face you.
As for preparation, it’s crucial to have the Swift Step ability unlocked and mastered, which can be found in the Deep Docks area. Given that you’re already exploring Shellwood, you likely possess this ability. Ensure you’re proficient in its use to sidestep rapid attacks during the encounter.
Strategies for Defeating Sister Splinter
Phase One
At the onset of the battle, Sister Splinter may seem daunting; however, the encounter can be manageable with the right approach. Her primary attack consists of three successive ground pounds, which will increase in intensity as the fight progresses, but not in speed— a fortunate detail!
As the fight commences, be prepared for her initial triple pound attack, which she will execute while following Hornet. Maintaining constant movement and using your dash ability effectively is essential to dodge her assaults.
While evading her strikes, look for openings to land two or three hits. The key here is to remain aggressive; hesitating can lead to a rough confrontation.
After her initial attacks, Sister Splinter will vanish, calling forth spiked vines to restrict your movement. Break these vines efficiently, or lure her into destroying them with her own pounds. Maintain this cycle until she screams and collapses, signaling the transition to Phase Two.
Phase Two

As Phase Two begins, Sister Splinter will summon two common enemies from either side of the arena. You can anticipate their entrance by observing the dust on the ceiling, allowing you to position yourself for an immediate attack upon their arrival.
Be mindful that these minions require three hits to defeat: focus on eliminating one before turning your attention to the other. Avoid getting trapped by their movements!
Once you clear the minions, Sister Splinter will reemerge, escalating her triple pound attack along with additional spiked vines to further complicate the battle. Stick to the tactics utilized in Phase One, but remember to capitalize on every opportunity to strike her.
As she screams and collapses once more, prepare for the final phase of the battle.
Phase Three

Entering the final phase, Sister Splinter intensifies her attack strategy, summoning both minions and spiked vines while continuing her ground pounds. Always remain alert and ready to dash to avoid her powerful strikes.
Eliminate the new minion as swiftly as possible while keeping an eye on Sister Splinter’s movements, dodging her attacks as needed. Utilize the chaos to your advantage, prompting her to destroy her own vines as they clutter the battlefield.
Your strategy remains consistent: focus on disabling the obstacles before turning your full attention to Sister Splinter. Avoid being cornered by either her minions or the spiked vines to ensure Hornet’s survival.
Ultimately, this boss battle is not overly complex if you focus on clearing distractions and dealing damage effectively.
Rewards for Conquering Sister Splinter

In Hollow Knight: Silksong, many bosses yield no immediate tangible rewards apart from granting access to new regions or instilling a sense of accomplishment. Sister Splinter is no exception. By defeating her, you unlock access to the upper section of Shellwood, leading to the coveted Cling Grip ability, essential for traversing walls effectively.
