The Architect’s Key in Hollow Knight: Silksong offers access to one of the strongest endgame Crests in the game. Finding the use for the Key is easy; however, finding the Key itself can be a bit confusing. This guide will help you find the Architect’s Key and use it to get the Architect’s Crest, which will be a worthy addition to your coterie of Crests. Stack up on some Rosaries, as you’ll need quite a few of them in this journey.
How to Get the Architect’s Key In Silksong
The Architect’s Key can be purchased from the Twelfth Architect at the Underworks, just beside The Cauldron. Fast Travel to the area as shown in the map above at the Underworks, then head right.
Keep heading right until you reach two levers: one at the bottom and one at the top. Jump up to the platform above Hornet, and hit the lever to open up a pathway to the area straight ahead. Continue moving right, then drop down, and head to the next area through the opening to the right.
As soon as you enter the next area, jump up using your Cling Grip through the narrow opening between two platforms, and keep heading right. You’ll find another narrow opening on the ceiling, which will give you access to the upper area. Jump up and head through the opening.
Once you’re in the upper section, turn left and jump up through yet another narrow opening, then climb onto the platform that’s located in the middle. Use your Cling Grip to jump from wall to wall, then jump onto the platform and keep heading right.
Continue progressing right to come across a Bench, where you can save your checkpoint, with another lever just beside it. You don’t need to hit this lever.
Instead, look for a few chains above the lever. You can climb up using these chains. Jump up using the chains to the platform located at the top right. Here, you need to hit the lever on the platform, located on the wall to the right.
When you hit the lever, the path ahead will open up, giving you access to the room where the Twelfth Architect is located. Interact with her to view the collection of items at her shop. You’ll need to purchase a few items before you can get the Architect’s Key to build trust with her. Once you’ve done that, the Architect’s Key will be available for purchase at 110 Rosaries.
Where to Use the Architect’s Key In Silksong
The Architect’s Key can be used at the Architect’s Door, located at the Twelfth Architect’s location itself. Inside the Twelfth Architect’s room, head right to find another lever on the wall. Hit the lever to open up a new pathway, then continue forward to find another opening above you. Jump up through the opening using your Cling Grip ability, then head left.
Here, you’ll find another lever on the left wall. Hit the lever to open up the next path. Then, jump across and head to the platform at the bottom left. There will be another lever on the wall. Interact with this lever to open the pathway in front of you.
Continue left and you’ll eventually come across a new door, where you’ll get the prompt to inspect. This is the Architect’s Door, which bears the Architect’s symbol. You can use the Architect’s Key to unlock this door.
How to Get the Crest of Architect In Silksong
Head inside the Architect’s Door, after unlocking it with the Architect’s Key, to access the Chapel of the Architect. Here, you need to continue right until you come across a point of interest with the ‘Claim’ prompt, hovering above it.
Bind yourself with the new Crest to unlock the brand new Crest of Architect, which offers a Silk Bind effect, and refills Hornet’s Red Tools’ ammo. It’s one of the more powerful endgame Crests you can unlock in the game.
That’s all you have to do to find the Architect’s Key and use it to obtain the Crest of Architect in Hollow Knight: Silksong. There are many more Keys that you can search for in the game, so check out our guides on the Key of Indolent and Key of Heretic.
