How to Find and Defeat Sister Splinter in Silksong - Shellwood

Location, Moveset, Counters, and Cling Grip Unlock

Sister Splinter is one of the more punishing mid-game bosses in Hollow Knight: Silksong, and she’s tucked away deep within Shellwood—a biome that tests your platforming skills and patience. With her vine-summoning attacks, flying allies, and the infamous Triple Slam combo, Sister Splinter can easily overwhelm players who aren’t prepared. But once you learn her patterns and manage the chaos in her arena, the fight becomes much more manageable. Here’s a complete guide to locating Sister Splinter, mastering her moveset, and unlocking the Cling Grip ability after the fight.

🧭 Where to Find Sister Splinter

Sister Splinter is located in the upper-left section of Shellwood, to the left of Bellhart. To reach her:

Progress through the lower layers of Shellwood until you reach a vertical shaft on the far left.

Climb up and take the top-right exit into a large room with a Weaver statue at the top.

Exit right, platform through the next room, and unlock the elevator shortcut above the central Bench.

From the Bench, take the elevator up, go right, and use downward slashes on white flowers to reach the top-left exit.

Continue left until you hit the boss arena—marked by spiked vines that trap Hornet inside.

🛏️ Closest Bench and Runback Route

The central Bench in Shellwood is your best bet forretrying the fight. It’s connected to the elevator shortcut you unlocken route to Sister Splinter. The Bench costs 60 Rosaries to activate, but it’s worth every shard.

To run back:

• Take the elevator up.
• Exit right and platform through the top-right room.
• Use the white flowers to reach the top-left exit.
• Continue left to re-enter the boss arena.

⚔️ Sister Splinter Moveset and Counters

Sister Splinter’s fight revolves around three core mechanics: slams, vines, and flying allies. Here’s how to counter each:

Triple Slam

• Visual Cue: Raises one arm briefly before slamming down.
• Pattern: Alternates between left and right three times.
• Counter: Dodge in the opposite direction of each slam. If her right hand is active, dodge left. Repeat for the next two slams.

Tip: Use Silkspear or break vines with your Needle to create space for dodging.

Summon Ally

• Visual Cue: Roars and retreats into the ceiling. Wall lights indicate spawn points.
• Counter: Attack her during the roar (4–5 hits possible). Use Tools like Longpin or Silkspear to quickly eliminate flying enemies.

Tip: Flying allies can pass through vines, so clear them fast to avoid getting cornered.

Summon Thorn Vines

• Visual Cue: Retreats into the ceiling; beams indicate vine launch direction.
• Counter: Hit vines three times with your Needle or use Silkspear to break multiple at once.

Tip: Prioritize breaking vines near the center to maintain mobility.

Multi-Thorns

• Visual Cue: Six beams appear across the ceiling; vines launch from outside in.
• Counter: Position Hornet between two beams to avoid damage. Use Silkspear to clear multiple vines instantly.

Tip: If low on Silk, clear the center manually, then move toward one wall and break vines as you go. Vines stop respawningafter three waves.

🧠 Boss Tips and Loadout Suggestions

• Use Longpin: Its arc can hit both Sister Splinter and flying enemies near the ceiling.
• Equip Reaper Crest: Its wide slashes help manage vines and minions simultaneously.
• Threadstorm: A wide AoE ability that clears space and punishes grouped enemies.
• Warding Bell: Shields Hornet during healing and reflects damage back at attackers.

Combat Rhythm: During Triple Slam, jump and strikebetween slams to land extra hits. Be aggressive during her roaranimation and use Tools to control the arena.

🎁 What You Unlock After the Fight

Defeating Sister Splinter opens up the rest of Shellwood, including access to the Cling Grip ability. After the fight:

Exit left from the boss arena.

Navigate around the central pillar.

Find the Weaver statue and Bind in front of it.

Cling Grip lets Hornet grab vertical surfaces and wall jump, unlocking new traversal options across Pharloom. You’ll need it to reach the Widow boss and continue the Bellhart storyline, but it also opens up previously inaccessible areas in earlier zones.

Sister Splinter is a test of patience, positioning, and crowdcontrol. Once you learn to manage her vines and flying allies, the fight becomes a dance of dodges and counterattacks. And with Cling Grip inhand, you’ll be ready to scale new heights—literally.
