The mysterious Cultist Lair is one of the most intriguing and secretive locations added to Fisch. Hidden deep beneath Terrapin Island, this eerie area is filled with strange rituals, hidden treasures, and exclusive rewards.
Reaching it, however, isn’t as simple as sailing in – it requires exploration, the right items, and a specific weather condition.
Here’s everything you need to know about how to get to the Cultist Lair in Fisch, including the coordinates, required totems, and step-by-step instructions to unlock its entrance.

The Cultist Lair is a hidden underground area introduced with a recent update in Fisch. It’s located within Terrapin Island, home to the Sea Traveler NPC and the rare Sea Turtle species.

Accessing it isn’t straightforward. You’ll need to complete a few tasks, obtain a special note, and use two specific totems under the right conditions.
Cultist Lair Coordinates in Fisch

If you use your in-game GPS or compass, this will take you straight to the hidden entrance on Terrapin Island.
How to Get to the Cultist Lair in Fisch
Follow these steps carefully to unlock and access the Cultist Lair:
Step 1: Travel to Terrapin Island
Start by sailing or teleporting to Terrapin Island, one of the key fishing zones in Fisch. Once you arrive, you’ll need to find the Sea Traveler NPC. You can use your Fisch GPS to locate him at coordinates 151, 150, 2033.
He’s usually found standing near the water, fishing quietly.
Step 2: Get the Sea Traveler Note
The Sea Traveler is the key to discovering the lair’s location.
-
Talk to the Sea Traveler NPC multiple times.
-
Catch a Sea Turtle — a fish species found around Terrapin Island — and hold it in your inventory.
-
Speak to the NPC again while holding the Sea Turtle.
He will give you the Sea Traveler Note, which reveals the coordinates to the hidden area: 0, 150, 2000.
Tip: If you already know the coordinates, you can skip this step and head straight to the hideaway.
Step 3: Find the Terrapin Hideaway
Next, head toward the back side of Terrapin Island. Look for another NPC who’s fishing — this spot marks the path toward the secret hideaway.
From there:
-
Climb up the rocks behind the NPC.
-
You’ll find a leaf-covered cave entrance.
-
This cave leads directly to the Cultist Lair entrance area, also known as the Terrapin Hideaway.
Step 4: Unlock the Cultist Lair Entrance
Here’s where things get tricky. The lair doesn’t stay open all the time. You’ll need two totems and the right environmental setup to reveal the entrance.
You’ll need:
-
Sundial Totem – to change the time to night.
-
Smokescreen Totem – to create fog.
Follow these steps:
-
Enter the cave area at the hideaway.
-
Use the Sundial Totem to make it night.
-
Then use the Smokescreen Totem to make it foggy.
-
Once it’s both nighttime and foggy, a hidden lever will appear inside the cave.
-
Interact with the lever to open the entrance to the Cultist Lair.
You’ll know it worked when the cave wall shifts and reveals the lair’s passage.
