Learn how to get the Architect Key in Hollow Knight Silksong, unlock the Chapel, and claim the powerful Architect Crest with its unique tool-crafting ability.
The Game-Changing Architect Crest: Why It’s Worth the Hunt
When it comes to crest upgrades in Hollow Knight Silksong, the Architect Crest stands in a league of its own. Unlike other crests that simply modify your combat stats or movement abilities, this powerhouse introduces an entirely new gameplay mechanic: on-demand tool crafting using Silk.
This isn’t just another damage boost or speed enhancement – the Architect Crest fundamentally changes how you approach problem-solving throughout Pharloom. Imagine being able to craft the exact tool you need for any situation, right when you need it. That’s the power waiting for you in the Chapel of the Architect.
Act 2 Prerequisites: Your Journey to Eastern Underworks
Before you can even think about getting your hands on the Architect Key, you’ll need to complete significant portions of Act 2. This isn’t an early-game pickup – it requires dedication and skillful navigation through some of Silksong’s most challenging areas.
Essential Progression Steps:
- Complete Act 1 – Obviously, but worth mentioning for newcomers
- Navigate through Underworks – The industrial nightmare zone
- Reach Coral Chambers – A pivotal transition area
- Acquire movement abilities – Specifically the Clawline grappling hook
Pro tip: Before attempting this quest, make sure you’re comfortable with advanced platforming. The Eastern Underworks section includes some brutally difficult jumping sequences that will test every skill you’ve learned.
The White Key: Your Gateway to Whiteward
The path to the Architect Key begins with securing the White Key, and this journey alone showcases Silksong’s interconnected world design brilliantly.

White Key Location and Route:
- Head to the Citadel’s top-right section – This requires significant exploration
- Enter the Songclave – A mysterious musical-themed area
- Locate the White Key – It’s well-hidden but unmistakable when found
- Return to unlock the elevator access – This grants passage to Whiteward
- Navigate to Eastern Underworks – Your ultimate destination
Important note: The elevator journey to Whiteward is more than just transportation – it’s a gateway to entirely new areas and opportunities. Take time to explore thoroughly.
Mastering the Eastern Underworks: Platforming Hell Awaits
Here’s where things get seriously challenging. The Eastern Underworks represents some of Silksong’s most demanding platforming, combining environmental hazards with precision jumping requirements that will push your skills to the limit.
Navigation Strategy:
- Find the talking NPC’s bench – This serves as your orientation point
- Note the inaccessible NPC location – You’ll return here later
- Head left, then down to the lava level – Environmental hazards are real threats
- Navigate right through platforming gauntlet – Patience is absolutely crucial here
- Reach the central Eastern Underworks – Your destination for the Clawline ability
Survival tips for the lava sections:
- Take your time – Rushing leads to mistakes and death
- Study enemy patterns before engaging
- Use healing opportunities wisely
- Practice difficult jumps at safe sections first

The Clawline: Your Key to Vertical Freedom
The Clawline grappling hook isn’t just necessary for reaching the Architect Key – it’s a game-changing tool that opens up exploration possibilities throughout Pharloom. Think of it as your ticket to previously inaccessible areas and secrets.
Clawline Applications:
- Vertical traversal – Reach high platforms and secret areas
- Combat mobility – Escape dangerous situations quickly
- Puzzle solving – Many mechanisms require grappling hook interaction
- Sequence breaking – Access areas in unintended orders
Once you’ve secured the Clawline, return to that bench where you heard the NPC talking. Now you can finally reach them using the newly available grapple points.
Meeting the Twelfth Architect: Your Tool Vendor and Key Source
The Twelfth Architect represents one of Silksong’s most important NPCs, and not just because they hold the key you need. This character serves as a crucial tool vendor and represents the game’s deeper lore about the ancient architect civilization.
What the Twelfth Architect Offers:
- Multiple tool purchases – Expand your capabilities significantly
- The coveted Architect Key – Priced at 110 Rosaries
- Lore and backstory – Learn about the architect civilization
- Tool requirement gates – Purchase blocked until you own sufficient tools
Critical requirement: The Architect Key purchase is locked behind a tool ownership requirement. The game will display exactly how many tools you’re missing when you attempt the purchase. This encourages thorough exploration and tool collection before accessing the crest.
Smart Shopping Strategy:
- Gather Rosary Beads first – 110 is a significant investment
- Collect required tools – Check what you’re missing before the trip
- Consider tool synergies – Some combinations work better together
- Plan your purchase order – Tools may help with upcoming challenges

Chapel Access: The Three-Lever Puzzle
Once you’ve purchased the Architect Key for 110 Rosaries, accessing the Chapel requires solving a multi-step lever puzzle that showcases clever level design.
Step-by-Step Chapel Access:
- Move right from the Twelfth Architect – The first lever is nearby
- Activate the first lever – This opens the initial pathway
- Head up and turn left – Navigation requires careful attention
- Hit the second lever – Positions you above the Architect
- Jump and dash left – Precise movement required here
- Activate the third lever – Opens the final passage
- Locate the locked gate – Look for the distinctive architect symbol
- Use your Architect Key – Finally unlock the Chapel entrance
Design appreciation: This lever sequence isn’t just busy work – it demonstrates the architects’ sophisticated engineering and serves as a mini-puzzle that tests your spatial reasoning.
The Chapel of the Architect: A Peaceful Sanctuary
Here’s something refreshing: unlike most other chapels in Silksong, the Chapel of the Architect contains no boss fights or enemy encounters. It’s a peaceful sanctuary dedicated to creation rather than destruction, which perfectly reflects the Architect Crest’s tool-crafting nature.
This design choice feels intentional and meaningful – while other crests might be won through combat prowess, the Architect Crest rewards exploration, puzzle-solving, and resource management instead.
Claiming Your Prize:
- Enter the peaceful chapel – Take a moment to appreciate the architecture
- Locate the Architect Crest – It’s prominently displayed and impossible to miss
- Use your Bind ability – Required to claim the crest
- Equip immediately – Start experimenting with its unique abilities
