Palworld’s recent collab with Terraria added a lot of new islands, one of them being the Sealed Realm of Terraria, featuring Eye of Cthulhu as the boss. This dungeon is also the only way to acquire the Celestial Sigil required for fighting the new raid boss, Moon Lord.
Along with the iconic boss fights, there are also a lot of schematics to find inside the dungeon's treasure chests, and this guide will help you navigate the entire place so you don’t miss anything.
Palworld Terraria dungeon location and walkthrough
The Terraria dungeon can be found on Eternal Summer Isle, located near the Fisherman’s Point fast-travel point. You can reach the island by traveling Southeast of the port, at coordinates (-422, -796).
Once inside, you’ll find many familiar things from Terraria, including Slimes and Demon Eyes, alongside new Pals added to the game. Navigating the dungeon can be tough, as the entire area is built like a maze, with only one way to reach the boss room.
Follow the steps below if you are planning to do a speed run.

1) Take the left cave upon entering the second room. You’ll reach the third room with two stones in the middle.

2) Take the right cave upon entering the third room to reach an area with a deserted house and water.

3) Exit the area through the water and take the left cave until you reach a hole through which you can drop down into a mine with purple stones.

4) Keep moving forward until you reach a room with two golden walls. Breaking the right one will open up another path.

5) Break the first golden wall you come across to open up the path to the boss arena.

Things you don’t want to miss in Palworld Terraria dungeon

Apart from picking up the treasure chests, you can also farm Hallowed Bars and Life Crystals inside the dungeon. Hallowed Bars are used for crafting all the weapons and armor found inside the Terraria dungeon. They are weightless and can be acquired by defeating enemies, looting chests, and breaking pots.
Life Crystals are located in the same spot each time you enter the dungeon. After crossing the third room and entering a cave, go straight towards the small cave instead of going left for the boss room. Along the edge of a pool, you’ll find a heart-shaped crystal that grants 2x Life Crystals.
