Exploring Ocean Biomes and Sunken Laboratories

Targeting Biomes for Specific Resources

Different ocean biomes contain distinct materials and vastly different threat levels. Plan your diving routes around what you need to harvest:

• Forgotten Plateau: Visit this sandy seabed to mine Blue Crystals, but watch out for Electribbons and aggressive Sand Stingers.
• Heat Mushroom Field: Dive into this hot biome to gather Flame Crystals and Heat Mushrooms while avoiding Ghost Worms.
• Thorny Forest: A quiet zone where you can collect thorny resources around Heat Slugs and Sawblade fish.
• Silent Field: Search among the strange trees in this dark green area for unique loot while staying alert for lurking threats.
• Void Forest: Avoid this forest until you are well armed, as its void trees shelter Void Fish, Ghost Worms, and dangerous Dragon Sharks (unlike the barren Dead Void Forest).

Clearing Sunken Laboratories and Ruins

Over fifty structures generate on the seabed, including dark stone towers, ruined bases beside ocean bridges, and glowing Flame Crystal Teranium laboratories. Before entering an enclosed Teranium lab, bring weapons, armor, and extra Teranium batteries. Sunken laboratories are often filled inside with hostile Devourers—clear hallways methodically and remember your way back out.
