How to Beat Sister Splinter in Hollow Knight Silksong

• Destroy the Thorns Quickly

The Sister Spinter can shoot out thorns that will block off parts of the arena. Break these thorns as soon as possible to clear space for movement and dodging.

• Defeat Flying Enemies First

During the fight, Sister Splinter may summon flying foes to harass you. These enemies restrict your ability to jump and dash effectively, so it’s best to take them out immediately before resuming your focus on the boss.

• Use Thread Storm

The Thread Storm ability unleashes a large area-of-effect strike that damages all enemies caught in its threads. With limited space in this battle, it becomes especially effective for clearing adds and hitting Sister Splinter at the same time.

Unlock Thread Storm by interacting with the statue north of Craw Lake in Greymoor.

• Use the Warding Bell to Counter Attack

The Warding Bell charm allows Hornet to reflect incoming damage while healing. This can be a lifesaver when you’re cornered with no space to dodge—time your heal to create a defensive shield and counterattack simultaneously.
