Learn how to craft the Cogfly tool in Hollow Knight Silksong. Find the High Halls location, get Craftmetal, and unlock powerful flying companions for combat and quests.
Your Personal Air Force: Understanding the Cogfly Tool
In the challenging world of Hollow Knight Silksong, few tools offer the tactical versatility of the Cogfly. This remarkable device doesn’t just add another attack option to your arsenal – it fundamentally changes how you approach both combat and exploration by providing autonomous flying companions that fight alongside you.
Think of the Cogfly as your personal squadron of mechanical allies. These aren’t just decorative pets; they’re strategic combat assets that can turn the tide in difficult battles, especially against aerial enemies that love to stay just out of your needle’s reach.
Why the Cogfly Tool Deserves Your Attention
The Cogfly represents one of Silksong’s most innovative tool concepts, offering benefits that extend far beyond simple damage dealing:
Combat Applications:
Aerial enemy control – Perfect for flying foes that frustrate ground-based fighters
Time-sensitive challenges – Provides support during no-damage delivery runs
Crowd control – Manages enemies while you focus on objectives
Tool synergy – Combines with other tools for devastating effects
Pro tip: The Cogfly’s true power reveals itself when combined with the Pollip Pouch from the Rite of the Pollip quest, adding venom damage that transforms your flying companions into lethal poison-dealers.
Prerequisites: Skills You’ll Need for the Journey
Before attempting to reach the Cogfly’s location in the High Halls, ensure you have these essential movement abilities:
Warning: Attempting this route without both abilities will result in frustration and impossible barriers. The High Halls’ vertical design assumes you have mastered these movement techniques.
Additional Preparation:
Craftmetal – Required for tool construction (we’ll cover sources below)
Combat readiness – The High Halls contain challenging enemies
Patience – This is a complex navigation sequence that rewards careful progression
Craftmetal Sources: Fuel for Your Flying Factory
Before diving into the High Halls expedition, you’ll need Craftmetal to actually construct the Cogfly tool once you find it. This valuable resource has several reliable sources:
Early Game Source:
Pebb in Bone Bottom – Purchase from this merchant early in your journey
Exploration Rewards:
The Marrow near Hunter’s March – Hidden in exploration areas
End of the lake in Fleatopia – Requires thorough area exploration
Various hidden locations throughout Pharloom
Resource management tip: Craftmetal is valuable enough that you should gather it whenever possible. Having multiple units available allows for immediate tool crafting when opportunities arise.
Route Planning: Two Paths to the High Halls
The journey to the Cogfly begins at the top western corner of the Choral Chambers, but you have two viable approach routes depending on your familiarity with the area.
If you’ve already learned the Conductor’s Melody, you can use that familiar route:
Head left from the starting point
Glide down to reach the station and bench
Use established navigation patterns
Route Option 2: Grand Bellway Route (Recommended for Most Players)
For a more straightforward approach:
Travel to the Grand Bellway – Use fast travel if available
Proceed to the Cogwork Dancers boss room – This serves as your navigation landmark
Begin the High Halls ascent from there
Navigation tip: The Cogwork Dancers boss room provides an excellent reference point because it’s a memorable landmark that most players will recognize.
Step-by-Step High Halls Navigation
Phase 1: Initial Ascent from Cogwork Dancers
Head left from the boss room – Maintain this direction consistently
Continue until you spot a bench – This serves as your first checkpoint
Double jump upward – Use Faydown Cloak to reach higher platforms
Harpoon into the rings – Use Clawline to grapple onto hanging anchor points
Repeat the ring sequence – Multiple grapple points lead progressively higher
Reach the top of this section – You’ll know you’re there when the environment changes
Phase 2: Horizontal Water Room Navigation
Proceed right – Enter the wide horizontal chamber
Note the running water and platforms – You’re now officially in the High Halls
Platform hop strategically – Jump across the water-filled room
Use rings when necessary – Grapple points fill gaps between platforms
Progress to the next room – Continue the eastward movement
Phase 3: Giant Wheel Challenge
Look up to spot the giant spinning wheel – This is a major navigation landmark
Harpoon into wheel rings – Timing is crucial as the wheel rotates
Ascend to the upper wheel – There’s typically a second wheel above the first
Combine skills for vertical progression – Use double jump, dash, and grapple in sequence
Enter the right-side room – This leads to the next navigation phase
Phase 4: Enemy Platform Section
Navigate enemy-filled platforms – Similar to your initial High Halls entry
Hook onto floating rings – Use established grappling techniques
Move forward to the following room – Continue progression toward your goal
Phase 5: Spike Descent Challenge
Look down and prepare to glide – This section requires precise timing
Avoid the spike obstacles – Glide carefully while watching for threats
Quickly use Clawline – Grab onto the ring as soon as it’s safe
Watch spikes retract – The obstacles remove themselves once you’re positioned correctly
Continue downward descent – Use the same technique repeatedly
Locate the enemy across the left path – This marks your destination approach
Claiming Your Prize: Cogfly Tool Construction
Final Steps:
Enter the left room – The enemy marks the correct passage
Navigate to the end of the path – The Cogfly tool awaits
Inspect the tool location – Interact with the crafting station
Use Craftmetal to construct – Transform raw materials into functional tool
Rest at a bench – Required to equip your new Cogfly tool
Construction note: The crafting process is immediate once you have the required Craftmetal, but you must rest at a bench before the tool becomes available in your equipment menu.
