Silksong Boss Guide: Defeat Sister Splinter and Claim Cling Grip
Sister Splinter boss guide: master three phases, manage vines, and defeat reinforcements to claim Cling Grip in Hollow Knight: Silksong.
Players chasing wall-climbing freedom in Hollow Knight: Silksong will eventually meet Sister Splinter, a required Shellwood boss who guards the route to Cling Grip. As of 2026, the encounter remains a three-phase test of needle work, Silk management, and arena control. The fight does not exactly roll out a welcome mat: Sister Splinter hangs above the action, sends savage vines into the rafters, and later calls in bulky reinforcements. Yet her move list is short, and once players learn to make proper use of Silkspear, she is a walk in the gardens.
Where Sister Splinter Fits in Shellwood
Located in the heart of Shellwood, Sister Splinter is the main hurdle to joining both halves of the map and reaching Cling Grip. Unlike other bosses up to this point, she has three distinct phases. The ceiling becomes her stage, and the vines have a habit of crowding the floor whenever players try to settle into a rhythm. That is why the encounter is less about raw damage and more about keeping the arena from turning into a thicket.
Players who let the field fill with vines and splinterbarks will find themselves boxed in fast. Those who clear threats early, however, can dictate the pace of the fight. The boss herself is not the hardest part once her patterns are understood; the real challenge is refusing to let her extra tricks pile up.
Phase-by-Phase Priorities
Phase
New Wrinkle
Player Priority
Phase One
Vine zoning and a three-hit combo
Clear threatening vines with Silkspear; punish after the combo
Phase Two
Splinterbark reinforcements, often summoned first
Lay Sting Shard traps; remove stragglers quickly
Phase Three
A new vine attack and more numerous vines
Keep the field clear and avoid being overwhelmed
Each time Sister Splinter is staggered, she falls to the ground. When she returns to the ceiling, she moves to the next phase. Phase Two begins with reinforcements, and Sister Splinter almost always opens with them. Phase Three begins with her new vine attack, and all vine attacks become more numerous in appearance.
Managing Vines and Reinforcements
The main priority of this fight is to ensure that the vines and, after the last two phases, her reinforcements do not overwhelm the player. To accomplish this task, the recommended approach is straightforward:
Use Silkspear to quickly remove vines that pose a threat.
Normally attack vines when Sister Splinter is missing to conserve Silk.
Lay Sting Shard traps to deal with splinterbark enemies.
If necessary, use Silkspear to remove splinterbarks quickly.
If Sting Shard traps are lacking in damage, purchase the crafting kit upgrade from the Forge Daughter in the Deep Docks.
This is a fight where tidiness pays. A single vine left alone can become a wall, and one ignored splinterbark can turn a clean attack window into a scramble. Players should treat crowd control as part of the boss damage rotation rather than a distraction from it.
Best Attack and Healing Windows
The best time to attack Sister Splinter is:
After her three-hit combo.
During the summoning of reinforcements.
When she falls to the ground during a stagger.
Likewise, players can choose to heal during these times and do so safely. There is no shame in taking a breath when the arena is under control; in fact, a quick heal often prevents the next mistake. The fight rewards patience more than greed.
Why the Fight Works
As long as players keep tabs on all the tricks Sister Splinter tries to play, she is a pushover herself. Keep the field clear, and the boss can be defeated at the player's own pace. The arena rewards discipline: remove the vines, thin out the reinforcements, punish the recovery windows, and repeat. The core lesson is simple, even if the execution takes a few attempts.
Sister Splinter drops no physical reward when she is eventually defeated. However, continuing left from her boss room brings players to a new area with several tricky platforming sections. Follow the path to reach Herrah's statue, then bind the power that the statue gives. The result is the highly valuable Cling Grip ability, which allows players to climb walls to new locations.
For anyone who has been eyeing distant ledges and unreachable routes, that reward is the real prize. Sister Splinter may guard the way, but she is ultimately a gatekeeper with a short move list and a very clear weakness: a tidy arena.
That same pull—chasing the next useful upgrade and seeing where it opens up—often carries over into how players shop for games and gear.
