Locate and Explore Underwater Structures

Understand Structure Distribution

Underwater structures spawn across different ocean biomes. Teranium laboratories, dark stone towers, and ruined bases are scattered throughout the seabed. Some biomes concentrate specific structure types—check the Silent Field and Void Forest for dense structure clusters.

Navigate to Structures

Swim along the ocean floor methodically. Structures are large enough to spot visually if you're patient. Use landmarks like unique rock formations or biome color changes to remember your path. The Water Jet Boots help you cover distance quickly while searching.

Enter Safely

Before entering a structure, ensure your Teranium batteries are fully charged and you have backup batteries in your inventory. Hostile mobs like Devourers and Dragon Sharks spawn inside structures. Bring a sword and consider wearing full Crystal Teranium Armor for protection.

Explore Interior Rooms

Move cautiously through hallways and chambers. Break decorative blocks and loot containers for rare items and resources. Watch for mob spawners and aggressive creatures in darker areas. Exit immediately if you're low on oxygen or health.
