Silksong Key of Apostate: My Painful Journey to Find and Use It

Find the Key of Apostate in Hollow Knight Silksong's Putrified Ducts using Clawline and Double Jump, then beat Groal.

Alright, fellow masochists—I mean, Silksong players. If you're stuck in The Slab, staring at locked doors like a raccoon trying to open a jar of pickles, you need the Key of Apostate. And let me tell you, getting this key is like trying to find a specific grain of sand on a beach while seagulls dive-bomb your head. But I did it, and I'm here to spare you some of the agony.

First, the key isn't even in The Slab. It's in Putrified Ducts. Of course it is. Because why make things simple? You'll need Clawline and Double Jump. No exceptions. If you don't have those, go get them. I'll wait. ️

Where to Find the Key of Apostate

There are two routes to Putrified Ducts. I tried both. One made me question my life choices; the other made me question the developers' childhoods.

Route
Starting Point
What You Need
Vibe

Upper
Memorium
Find a secret opening in the ceiling, climb, break a rock
Like sneaking into a VIP lounge through a vent

Lower
Bilewater
Defeat a boss
Like paying full price for a movie then realizing you left your wallet at home

I took the upper route first. From the top of Putrified Ducts (accessed from Memorium), I had to find a secret opening in the ceiling. Pro tip: it's in one of the rooms, and you'll need to walk to the end of Memorium, climb a wall, and destroy a breakable rock. Easy, right? No. It's like trying to find a light switch in a dark room while wearing mittens.

Once inside Putrified Ducts, the real fun begins. Start from the Bellway and climb up using Double Jump. You'll eventually reach Shakra's location. Use the vertical platforms as shields from enemy ranged attacks. I felt like a turtle hiding in its shell, except the shell was a floating platform and the turtle was a bug with a needle.

Then you Clawline your way across, cling to walls, and jump higher. There are green bulbs—use them. They're like nature's grappling hooks. Platform your way up, avoid spikes, shoot enemies with Clawline, and eventually you'll reach a room with temporary platforms over water. Don't fall. I fell. Twice. The water is not a jacuzzi.

After more climbing, Double Jumps, and Clawline shenanigans, you'll reach a boss fight. Prepare yourself. You'll first fight flying enemies that shoot from afar. Use Clawline to reach them and deal damage. Then Groal appears. He dives into the water and jumps up high, plunges, and shoots multiple projectiles. It's like fighting a caffeinated dolphin with a grudge. Once you win, go left, cut a rope to create a shortcut, and jump up to Putrified Ducts. Use the platform to go higher, enter a left tunnel, and beware of a big enemy in the dark. Deal with it or sneak past, jump to the left platform, destroy the glowing object, and claim the Key of Apostate. You can also start the Broodfeast quest here.

Where to Use the Key of Apostate

Now you have the key. Congratulations! You're still not done. The key can be used on two locks in The Slab. One unlocks a new area; the other reveals a puzzle.

First Lock: Enter The Slab Without Being Kidnapped

From The Slab Bellway, go up and turn right. Go through the door, go up to open a shortcut, then slide down. Proceed right into a room with lore tablets. Look up and combine Double Jump and Clawline to climb a tunnel. Enter the door at the end, keep going left until you see the Heretic Lock. Use the key. Now you can roam freely and gather the remaining keys. No more kidnapping. That's a win in my book.

Second Lock: The Puzzle

From the Heretic Lock, head up to find a bench sign. Continue climbing to the top to reach the second lock. Inside, there's a puzzle. Solve it to get a mask shard. Here's how:

• Press the button four times to spawn four wheels.

• Double Jump onto the platform above.

• Wait for a wheel to come closer, then use it to jump higher and cling to the left wall.

• Climb higher to easily jump on the two wheels and cling to the right wall.

• Wait for one wheel to approach the ledge, then jump on it to reach the platform.

• Grab the mask shard.

And that's it. You've done it. You've beaten the game's attempt to make you pull your hair out. I celebrated by eating a whole pizza and questioning why I play games like this. But hey, that mask shard is worth it. Probably.

So there you go. The Key of Apostate, found and used. May your Clawline always latch and your Double Jumps always land. ️

If you're anything like me, finishing a guide like this usually means you're already eyeing your next challenge. Whether that's another Metroidvania or a completely different genre, the real boss fight is often the price tag. That's where [game price tracker]( comes in—DealNest keeps an eye on discounts across stores so you don't have to camp on a dozen tabs waiting for a sale.

I've started checking DealNest before buying anything, and it's saved me from overpaying more than once. It's not flashy, just useful. If your backlog is already scary, at least you can fill it without draining your wallet.
