Hollow Knight: Silksong’s September 2025 update includes undocumented changes to crests, tools, and silk generation that are transforming gameplay strategies.
The Patch Notes Didn’t Tell the Whole Story
Hollow Knight: Silksong players are discovering that Team Cherry’s September 21 update went much deeper than the official patch notes suggested. While the documented fixes focused on obvious bugs like Shrine Guardian Seth’s boundary issues, hidden mechanical changes are quietly reshaping how players approach combat, tool usage, and crest selection.
Thanks to dedicated community members like YouTuber Visic digging into the game’s mechanics, we’re getting a clearer picture of how significantly this update altered Silksong’s gameplay balance. Some of these changes are game-changers that affect core strategies – and Team Cherry didn’t mention them at all.
The Silk Generation Revolution That Changes Everything
The most significant undocumented change revolves around charged attacks now generating silk. This isn’t just a minor tweak – it fundamentally alters the risk-reward calculation for aggressive playstyles, especially against flying enemies that have been giving players trouble.
How the new system works:
- Hunter’s Crest: Generates 2 silk per charged attack (major buff)
- Most other crests: Generate 1 silk per charged attack
- Witch Crest: Unchanged (no silk generation)
- Strategic impact: Charged attacks become resource-positive instead of just damage-focused
Why this matters: Silk management has been one of Silksong’s trickiest resource systems. Players previously had to choose between aggressive charged attacks and maintaining silk reserves for tools and abilities. Now, aggressive play actually generates the resources needed for extended combat encounters.
Crest Balance Changes That Nobody Saw Coming
The crest adjustments reveal Team Cherry’s approach to balancing without making dramatic announcements:
Hunter’s Crest (Major Winner):
- Double silk generation from charged attacks
- Improved synergy with aggressive playstyles
- Community hoping for further buffs to compete with “regular attacks”
Architect Crest (Major Nerf):
- 29% damage reduction – a massive hit for DPS-focused builds
- Significantly less viable for speedrun strategies
- Forces players to reconsider high-damage optimization builds
Other Crests:
- Witch, Wanderer, Reaper, Beast all see contextual changes based on tool interactions
- No major direct nerfs, but tool synergies shift their relative power
Tool Rebalancing That Rewards Specific Builds
The tool changes show Team Cherry targeting specific crest combinations rather than making universal adjustments:
Flintslate (Situational Buff):
- 50% damage increase with Hunter, Reaper, and Beast Crests
- Nerfs for Witch and Wanderer Crest users
- Major nerf for Architect Crest (compounding their damage reduction)
- Strategic implication: Encourages aggressive, mobile playstyles over pure DPS
Volt Filament (Significant Buff):
- Now increases skill damage in addition to its previous effects
- Makes electrical builds more viable across different encounter types
- Potential sleeper build that could emerge in speedrun meta
Cogwork Wheel (Inventory Nerf):
- Reduced carrying capacity from 16 to 10
- Forces more strategic usage rather than spam strategies
- Affects exploration pacing and resource management planning
What the Community Response Reveals
Reddit and community forums show mixed reactions that highlight how these changes affect different playstyles:
Positive Reception:
- Silk generation changes praised for making aggressive play more sustainable
- Hunter’s Crest buffs seen as step toward better build diversity
- Tool rebalancing appreciated for encouraging experimentation
Controversial Changes:
- Architect Crest nerf dividing optimization-focused players
- Cogwork Wheel limits frustrating players who enjoyed hoarding resources
- Some feeling that undocumented changes lack transparency
Reading Between the Lines: Team Cherry’s Design Philosophy
These hidden changes reveal important insights about how Team Cherry approaches post-launch balancing:
Focus on encouraging aggression: Silk generation rewards and Flintslate buffs push players toward active combat rather than passive, cautious approaches.
Reducing overpowered optimizations: The Architect Crest nerf specifically targets builds that were trivializing difficulty through pure damage scaling.
Promoting build diversity: Rather than universal buffs/nerfs, changes reward specific crest-tool combinations to create more viable playstyle options.
Stealth balancing approach: Major mechanical changes implemented without fanfare, letting players discover and adapt organically.
Impact on Different Player Types
Casual Explorers: The silk generation changes make combat more forgiving and resource management less punishing. Charged attacks feeling “free” reduces the anxiety around using abilities aggressively.
Speedrunners and Optimizers: The Architect Crest nerf forces route recalculation and build optimization. Expect significant shifts in speedrun strategies and leaderboard times.
Challenge Runners: Rebalanced tools and crests create new constraints and opportunities for self-imposed challenges. The Cogwork Wheel limit particularly affects item-limited runs.
Meta Chasers: Hunter’s Crest emergence as a more viable option diversifies the “optimal” build discussion and creates new theorycrafting opportunities.
Technical Implications of Undocumented Changes
Why Team Cherry might skip patch note documentation:
Experimental balancing: These changes might be A/B testing for future major updates, easier to adjust quietly than announce and walk back.
Community discovery engagement: Letting players find changes organically creates community discussion and engagement around mechanical depth.
Avoiding controversy: Major nerfs like Architect Crest’s 29% damage reduction would generate more backlash if prominently announced.
Iterative design: Small, frequent undocumented adjustments allow for rapid response to emerging gameplay patterns.
Strategic Advice for Current Players
If you’re running Architect Crest builds: Time to experiment with alternatives. The 29% damage nerf is substantial enough to potentially make other options more efficient.
If you’ve been avoiding Hunter’s Crest: Worth revisiting. The double silk generation from charged attacks significantly improves its viability, especially for aggressive playstyles.
If you rely heavily on Cogwork Wheel: Start practicing more conservative usage patterns. The inventory reduction from 16 to 10 requires more strategic planning.
For tool-focused builds: Experiment with Flintslate and Volt Filament combinations. The buffs might make previously marginal builds surprisingly effective.
What This Means for Silksong’s Future
These stealth changes suggest Team Cherry is actively monitoring gameplay data and making targeted adjustments based on player behavior patterns. The focus on encouraging aggression and reducing overpowered optimization builds indicates they’re trying to guide players toward their intended gameplay experience.
Expect more undocumented changes: This update establishes a precedent for mechanical adjustments that bypass traditional patch note announcements.
Build diversity focus: The targeted nature of these changes suggests Team Cherry wants multiple viable approaches rather than dominant strategies.
Community-driven discovery: The reliance on players like Visic to document changes creates ongoing engagement and discussion around game mechanics.
The Bottom Line
Hollow Knight: Silksong’s September update proves that the most important changes aren’t always the ones that make headlines. While official patch notes focused on obvious bugs and balance tweaks, the real story lies in mechanical adjustments that are reshaping how the game feels to play.
For players still working through Silksong: These changes generally make the game more forgiving for aggressive playstyles while reducing the effectiveness of pure optimization strategies.
For the community: The undocumented nature of these changes highlights the importance of player testing and documentation. Team Cherry seems comfortable letting the community discover and discuss changes organically.
Looking forward: If this update pattern continues, expect ongoing mechanical evolution that keeps Silksong’s meta dynamic and encourages experimentation over solved strategies.
The takeaway: Don’t just read patch notes – pay attention to how your favorite builds actually feel in practice. The most significant changes might be the ones Team Cherry doesn’t announce.
