Before you can challenge Cthulhu, you must be at least level 200. If you’re below this level, you’ll need to grind by fishing, completing quests, and selling catches to level up. After that, you'll need to go to Dreamers Crypt of Terrapin Island (GPS: 140, 150, 2050) in the First Sea.

Once you arrive, look for the Sea Traveler. This character stands near a large, greyed-out stone door at the back of the island. The NPC serves as the gatekeeper to the Cthulhu boss fight in Fisch. Once inside, talk to Silas and select the “I was always prepared” (or similar dialogue) when you speak to him.

After a short cutscene, you will be teleported into the Cthulhu boss chamber, where you must pick up the Keeper's Torch and use one of the many lanterns located around the arena to "imbue" it. By doing this, it will let you launch fireballs at the boss.

To actually beat Cthulhu in Fisch, you'll need to damage him by aligning your torch’s flame color with Cthulhu’s health bar phases (Red, Orange, Yellow, Green, Blue, Purple) by completing small parkour challenges to reach colored platforms. It's not too difficult, and most of you shouldn't have any issues.

After you have beaten Cthulhu, you can freely travel to the Second Sea by speaking to the Sea Traveler NPC in front of Dreamers Crypt.
