Sister Splinter Boss Guide

Learn how to beat Sister Splinter in Hollow Knight: Silksong! This guide covers her attacks, phases, and strategies to help you overcome this challenging boss.

Alright, let's talk about Sister Splinter. She's a bit of a tricky one, especially with those phases, but don't worry, we'll get you through it. She's got a few main moves, and the fight changes up a bit as you chip away at her health.

Stats / Weaknesses:

• Sister Splinter has three distinct phases, indicated by her roars.
• The Hunter or Wanderer Crests are recommended for their wider up-attack range.

Phases:

1. Phase 1: Starts with Ground Pound and Summon Vines.
2. Phase 2: Adds Summon Enemies (Splinterbarks).
3. Phase 3: Summons more vines and continues with Phase 2 elements.

Strategy:

• Ground Pound: Sister Splinter will follow you and slam her arm down. This always comes in sets of three, alternating arms. The best move here is to simply dash away. Stay close enough that dashing works, but not so close you get hit.
• Summon Vines: She'll retreat to the ceiling and summon vines that act as barriers. Rays of light will show you where they're coming. These take three hits to destroy and deal one damage if you touch them. They disappear if Sister Splinter hits them, or when you stun her.
• Phase 2 - Summon Enemies: After her first roar, she'll summon two Splinterbarks. These enemies spin and deal two damage if they hit you. They can be tough to hit normally. Your Silkspear ability is your best friend here, as it can one-shot them and also destroy any vines present. If you don't use Silkspear, be careful as they become small bladed tornadoes.
• Subsequent Summons: After the first time in Phase 2, she'll summon one Splinterbark at a time. Immediately use Silkspear to take it out.
• Phase 3: She starts this phase by conjuring a bunch of vines. Stick to the center and destroy them, or use Silkspear. She'll summon more vines than before, but otherwise, the fight continues with Splinterbarks and claw attacks.
• General Tip: Focus on the Splinterbarks when they appear, then use jumping up attacks to finish off Sister Splinter.

Once you finally take her down, you'll be able to continue exploring Shellwood and eventually find the Cling Grip ability, which is super useful for wall jumping!
