Many items are available for you to collect in in every biome, but some of the best ones to grab first lie deep within the waves of the Ocean environment. Every place in the game has its own unique enemies and materials for you to discover. Locations that exist in the Ocean can provide special resources you wouldn't be able to find anywhere else.
Once you discover the Ocean in the open world, you may want to craft a Portal in that leads back to your base. This allows you to transport whatever items you find in this biome into your storage space at home while you keep exploring the region. It would be wasteful to lose any hidden objects and buried treasures found along the shores of a beach or deep underwater.
The Ocean is surprisingly limited, but you can still find important items like Chitin, Serpent Scales, and Serpent Meat to craft better gear. The sea does not have as many secrets as other locations, like the Black Forest or Mistlands biome in. Thankfully, the resources you can get from here are incredibly valuable when used to construct powerful weapons and armor.
You can get Chitin in from a Giant Kraken lurking deep in the waters of the Ocean, which you can find by sailing around on a boat for long enough. The barnacles on this creature's back can be mined using a Pickaxe to produce Chitin. This material crafts items like the Abyssal Harpoon and Abyssal Razor, or two extremely strong weapons to wield against various enemies.
Sea Serpents are hostile creatures you may also find in the Ocean, and can be hunted down for their Scales and Meat. These enemies are a bit of a pain to track down since they move fast in the water and deal a large amount of damage when attacking. The Meat from these reptiles can add to your limited food supply to prolong your investigation of the biome on a raft or ship in .
Make sure to only attack Sea Serpents from above the water if you can, since these creatures will relentlessly attack you when you attempt to swim in the water
