Discovering Ocean Structures and Fossils
You can find unique structures and fossils in various ocean biomes. Ancient structures are places to explore, sometimes containing gilded chests with valuable items. Fossils are found by excavating suspicious gravel or sand in specific locations and can be revived using a resurrection machine.
Beach
Beach structures generate in beach biomes. The game attempts to place one of these structures within each 16x16 chunk region, ensuring at least 4 chunks separate them from other structures of this type.
Deep Ocean
Deep Ocean structures appear in deep ocean biomes. Similar to beach structures, one attempt is made to place a structure per 16x16 chunk region, with a minimum distance of 4 chunks between them.
Warm Ocean
Warm Ocean structures are found in warm ocean biomes. The placement logic for these structures is also one attempt per 16x16 chunk region, maintaining a separation of at least 4 chunks.
Prehistoric Hydrothermal Vents
Prehistoric Hydrothermal Vents generate in temperate ocean biomes. The placement for these vents is one attempt per 17x17 chunk region, with a minimum spacing of 5 chunks.
Lush Shipwreck Cove
Lush Shipwreck Cove structures appear in cold ocean biomes. These structures are less common, with one attempt made per 150x150 chunk region. They are also placed further apart, with a minimum distance of 75 chunks from other structures of this type.
Submerged Shipwreck Cove
Submerged Shipwreck Cove structures also generate in cold ocean biomes. Like Lush Shipwreck Coves, their placement involves one attempt per 150x150 chunk region, and they are separated by at least 75 chunks.
