Ocean



The Ocean is a large body of water found on the surface of each map at both left and right edges, comprising the eastern 500ft (250 blocks) and the western 500ft for large maps and 676ft (338 blocks) for medium maps. It extends as deep as the Cavern layer with maximum depth reached at the edge of the map.

Oceans will commonly contain Water Chests with loot pertaining to water. They also contain unique enemies like Crabs and Sharks.

The Ocean Biome contains its own tree type, Palm Trees (since 1.2.4), which can be harvested for Palm Wood.

Oceans have a 1/4 chance of generating Ocean Caves during world generation, which are water-filled tunnels beginning at the Ocean floor. These tunnels have a chance of generating with Water Chests and other standard underground items.

Tips

 * Players exploring the Ocean run the risk of drowning if not equipped with the proper accessories. In addition to plenty of healing potions, items and potions that aid breathing, such as the Breathing Reed and Gills Potion, a Magic Mirror for returning home quickly, and Flippers to aid swimming should be brought along. The Grappling Hook or Ivy Whip may also be of some help in returning to the surface for breath. The Neptune's Shell or any of its upgrades removes the need to breathe altogether.
 * Players may drain the Ocean by tunneling down to the Underworld, where water evaporates.
 * Another way of draining the Ocean is by making an air pocket, emptying a Lava Bucket in it and placing a background object (e.g. furniture) in the lava. Allowing water to flow in will cause it to disappear, as the object prevents Obsidian from being generated.
 * When attempting to preserve the Ocean biome from being converted in Hardmode, simply digging a quarantine gap under the seabed is insufficient because world data extends a little past the edge. The gap must thus be extended vertically along the edge right up to the sea bed, which needs to be plugged with incorruptible blocks to both prevent the water from draining as well as stop any spread of Corruption/Crimson or Hallow.
 * The Oceans have a lot of space, making them good places for large-scale builds like arenas and farms.
 * On the, the Angler, Pirate, and Stylist NPCs prefer the Ocean biome.
