The player character talks to the Silas NPC in the cave located in the Terrapin Island area in Fisch.

How To Access The Second Sea

The Second Sea is a vast new area filled with fresh challenges, equipment, and mysteries. But before you can explore it, you need to fulfill the main requirement in the First Sea -defeat the Cthulu Boss.

Start by heading to Terrapin Island, located southwest of Moosewoodat the following coordinates: -200, 130, 1925. Once there,walk to Dreamer’s Crypt, a hidden chamber locatedat coordinates: 140, 150, 2050. Enter the Dreamer’s Crypt andtalk to the Silas NPC. He will give you access to the battle with the Cthulu Boss,provided you are at least level 250.

The player character is fighting the Cthulu Boss using a Keeper’s Torch in Fisch.

How To Defeat The Cthulu Boss

Once inside the chamber, you will see a cutscene andreceive a Keeper’s Torch. To deal damage to the boss, you need toimbue this torch with a flame by interacting with the lanternsscattered around the battlefield.

However, there’s a key mechanic you need to pay close attention to -the colored bars below Cthulu’s health bar. These bars indicate which type of flame will do the most damage at that moment. Around the arena, on the platforms, you will find colored lanterns in the following order:

Your job is tomatch the torch’s imbued flame color with the current indicator under the boss’s HP bar. Imbuing your torch from the correct lantern will significantly increase your damage output. The lanterns are located onfloating platformsaround the arena, and to reach them you shouldcomplete short obby sections.

Be careful not to fall, though; take your time and jump carefully. Once you’ve reached a lantern of the matching color,interact to charge your torchand then return to attack.

The fight is easier with friends, as you canspread out and each take responsibility for a specific color. When the boss’s color shifts, swap positions, recharge the torch from the appropriate lantern and continue the attack.

Cthulu isn’t just a tanky boss - he hits hard too. Many of his attacks candeal massive AoE damage, so your best defense is mobility.Use theAdvanced Gliderto dodge incoming projectilesand reposition yourself quickly. Once you defeat Cthulu, a short cutscene will play again. After that, you will beteleported straight into the Second Sea area.

From this point on, you canfreely travel back and forth between the First and Second Seas. To do so,return to the Sea Traveler NPCon Terrapin Island or find his counterpart in Waveborne, the starter island of the Second Sea. Simplytalk to them and select “I was always prepared” to travel between locations.
