Sister Splinter Overview
Boss Characteristics:
Ceiling Dweller: Stays wedged in the ceiling for almost the entire fight
Limited Approach: Very specific attack patterns due to positioning
Area Guardian: Blocks access to the Wall Jump upgrade

Minion Management: Flying enemies distract from main fight
Core Combat Strategy
Essential Technique: Short Jump + Upward Strike
The key to defeating Sister Splinter is mastering the short jump combined with upward strike. This combo allows you to damage her while avoiding collision damage from jumping too high into her body.
Successful Tactics:
Short Jumps: Keep jumps low to avoid collision damage
Upward Strikes: Primary damage source throughout the fight
Evasion First: Dodge attacks before attempting to counter
Opportunity Attacks: Strike during recovery windows
Avoid These Mistakes:
High Jumps: Will result in collision damage with Sister Splinter
Attacking During Combos: Focus on dodging first
Ignoring Spikes: Clear path-blocking thorns immediately
Overcommitting: Don't get greedy with damage windows
Phase-by-Phase Breakdown
1 Phase 1: Basic Combat Introduction
Three-Hit Claw Combo
Attack Pattern:
Left Strike: First claw attack from left position
Right Strike: Second attack from right position
Final Left: Third strike returning to left
Counter Strategy:
Sister Splinter tracks your movements during this combo
Focus entirely on evasion during the three hits
Attack only after the combo finishes
Damage Window: Brief opportunity after third strike
Ceiling Spike Slam
Warning Signs:
Debris: Small pieces falling from ceiling
Light Ray: Bright beam emerging from above
Response:
Dodge immediately when you see warning signs, then attack the spike several times to destroy it
Escalation Pattern:
Initially spawns one spike at a time
Progressively spawns multiple spikes simultaneously
Failed to clear spikes = reduced dodging space
Critical: Clear spikes quickly or risk having nowhere to run during claw combos
Stun Window & Phase Transition
How to Trigger:
Deal enough damage during the brief windows after her claw combos. Consistent upward strikes will eventually stun her.
Visual Cue: Sister Splinter drops from ceiling to ground level
Maximize Damage:
- • Use your strongest available attacks
- • Attack rapidly while she's grounded
- • This window is brief but crucial
- • Significantly damages her health pool
- • Triggers transition to Phase 2
2 Phase 2: Enhanced Aggression & Minions
Phase 2 Begins:
After the stun window, Sister Splinter lets out a shriek and retreats. This signals the start of a more complex phase with additional threats.
Airborne Enemy Management
Enemy Behavior:
Initial Spinning: Enemies spin when first summoned
Unpredictable Movement: Erratic flight patterns
Distraction Factor: Makes dodging other attacks harder
Elimination Strategy:
Wait for Stop: Attack only after spinning stops
Silk Strikes: Ranged attacks work well
Triple Upward: Three quick upward stabs
Priority Target: Eliminate at all costs
Advanced Spike Patterns
New Attack Patterns:
Angled Spikes: No longer straight down - come at slight angles
Multiple Simultaneous: Several spikes at once
Minion Combination: Spikes while flying enemies are active
Adaptation Strategy:
Account for angled trajectories when dodging
Clear flying enemies first to reduce chaos
Maintain situational awareness of multiple threats
Key Insight: Flying enemies make spike dodging much more difficult
Arena Spike Flood
Final Escalation:
Sister Splinter screams and floods the entire arena with spikes, creating thorn walls throughout the battlefield.
Warning: This creates the most claustrophobic phase of the fight
Survival Strategy:
Limited Clearing: Only break enough walls for dodging space
Time Management: Don't waste time destroying all spikes
Focus Strikes: Prioritize attacking Sister Splinter over clearing
Final Defeat
Continue the back-and-forth pattern of dodging her attacks and striking during brief windows. Eventually, Sister Splinter will hit the ground for the last time, signaling your victory and unlocking the path to the Wall Jump ability.
