How to Unlock the Cultist Lair Fisch – Location, Requirements, and Complete Guide

The Cultist Lair has officially made its return in Fisch, introducing a mysterious new zone packed with quests, lore, and valuable rewards. This hidden area isn’t easy to access—you’ll need specific items, totems, and timing to uncover it. Here’s a step-by-step guide on how to reach the Cultist Lair on Terrapin Island in Fisch (Roblox).

Cultist Lair Location

The Cultist Lair is found at the exact coordinates 0, 150, 2000, located on Terrapin Island. To get there, you’ll first need to acquire the Sea Traveler Note, which reveals the hidden Terrapin Hideaway that leads directly to the Cultist Lair.

Before heading out, make sure you’ve unlocked Terrapin Island and have the required Sundial Totem and Smokescreen Totem, as they’re crucial to opening the lair’s entrance.

Step 1: Get the Sea Traveler Note

To begin, travel to Terrapin Island and locate the Sea Traveler NPC at coordinates 151, 150, 2033. Talk to him several times until he starts hinting at a secret.

Next, you’ll need to catch a Sea Turtle from the Terrapin Bestiary. Once you’ve caught one, hold the Sea Turtle in your hand and speak to the NPC again. He will reward you with the Sea Traveler Note, which contains the coordinates that lead to the Cultist Lair.

(If you already know the coordinates, you can skip this step and head straight to the location.)

Step 2: Find the Terrapin Hideaway

Open your GPS and head toward the coordinates 0, 150, 2000. When you arrive at Terrapin Island, look for the NPC fishing on the backside of the island. From that area, climb the rocks until you find a hidden cave covered in leaves—this is the entrance to the Terrapin Hideaway, which leads to the Cultist Lair.

The cave may be easy to miss, so look closely for areas that glow slightly or appear out of place compared to the surrounding terrain.

Step 3: Unlock the Cultist Lair Entrance

Once inside the hidden cave, you’ll need to perform a few specific actions to open the Cultist Lair:

1. Use the Sundial Totem to change the time to night.
2. Use the Smokescreen Totem to create fog.
3. When both conditions (night + fog) are active, a lever will appear inside the cave.
4. Pull the lever to open the Cultist Lair door and gain access to the new area.

If the lever doesn’t appear right away, double-check the time and weather effects—the Cultist Lair will only unlock during a foggy night.

Step 4: Explore the Cultist Lair

Once the door opens, step inside to enter the Cultist Lair. The area is filled with mysterious NPCs, lore-related items, and new quests to complete. Players can earn unique rewards and uncover more about the Cultists’ connection to the island’s history.

The Cultist Lair update adds a new layer of mystery and adventure to Fisch. While it takes some preparation to unlock, the rewards and exploration opportunities make it well worth the effort. So, Visit Terrapin Island and talk to the Sea Traveler. Obtain or skip to the Sea Traveler Note coordinates. Locate the hidden cave at 0, 150, 2000. Use Sundial and Smokescreen Totems at night to open the lair. Once inside, enjoy the new content and uncover the secrets that lie beneath Terrapin Island.
