Getting Started

There are two Oceans, one at either side of the map. In the early game, oceans mainly provide accessories and weapons to further improve your ability to travel through water. Additionally, they are the only source of Shark Fins, Coral, and Pirate Maps, as well as the dye materials Black Ink and Purple Mucus. In late Hardmode, it is usually visited to summon Duke Fishron by fishing with a Truffle Worm.

The main threat of the Ocean is the very water it is composed of, which players can drown in. Second to this are Sharks, which ambush players with high speed and melee damage.

Plundering

The ocean can be reached by travelling on foot to the edge of the world, using a Magic Conch found in the Underground Desert or Oasis/Mirage Crates, or teleporting with an Ocean Pylon.

Depending on game progression, you may have collected various equipment from Water Chests or Ocean Crates. Any of these items will make diving into the ocean much safer.

• Trident, greatly enhancing underwater movement speed and jump height while held
• Flipper, allowing the player to swim upwards by repeatedly pressing ↷ Jump
• Breathing Reed, doubling the time the player can spend underwater
• Inner Tube, allowing the player to rapidly float to the surface by equipping it

Other useful items include the following, which can be found commonly as part of normal chest loot:

• Gills Potion, allowing the player to breathe underwater for 4 minutes
• Shine Potion, providing light without the need to hold or throw Glowsticks
• Flipper Potion, which does the same thing as Flippers (see above)
• Recall Potion/Magic Mirror, used to teleport out instantly if the player gets attacked by a Shark or starts drowning

The Ocean contains Water Chests at its bottom, and has a 25% chance of extending into a cave-like structure which contains additional Water Chests. A quick but risky strategy to loot these chests early-game is to obtain a Recall Potion and Glowsticks and then immediately dive in, looting chests as quickly as possible until your breath runs out, at which point you drink the Recall Potion to escape. Lucky players may immediately find one of the above items and be able to continue their expedition, surfacing to breathe as needed.

Players may wish to collect Coral, an alchemy ingredient which grows on the surface of submerged Sand blocks.

Combat

As mentioned before, a great threat in the ocean comes in the form of Sharks. The countless Pink Jellyfish in the ocean can also be a problem if they swarm you, but their glow allows them to be seen at any distance and avoided easily. To deal with enemies, consider bringing a set of Iron armor or better, as well as a Spear, Boomerang, or any Gem Staff. Low-knockback weapons such as early Swords are useful against the Pink Jellyfish and Crabs, but cannot hold back a Shark.

Visibility is also a concern down at the ocean depths. While Pink Jellyfish give off light, Sharks and Crabs do not, and can strike unexpectedly from the darkness at any time. The most readily source of aquatic lighting available would be the Glowsticks dropped by jellyfish, as torches do not work underwater. The Mining Helmet or Shine Potion can help provide light, as well as the rarer Jellyfish Necklace dropped by jellyfish. A Hunter Potion can be used to clearly see the locations of enemies.You can also light your way using Star Fury sword.

Fishing

Fishing in the ocean yields some powerful pre-hardmode loot, all of which can be obtained as soon as the player obtains a fishing rod and bait. This makes ocean fishing an effective way to gain a head-start in the early-game.

Fishing in the ocean may grant the following crates:

Item	Rarity	Notes
Wooden Crate Internal Item ID: 2334	01*
Iron Crate Internal Item ID: 2335	02*	Uncommon
Golden Crate Internal Item ID: 2336	03*	Rare
Ocean Crate Internal Item ID: 5002	02*	Rare, pre-Hardmode only
Seaside Crate Internal Item ID: 5003	02*	Rare, Hardmode only

Late-Game Tips

A Diving Helmet dropped by Sharks will allow you to breathe underwater for much longer, and can be combined into Diving Gear and Jellyfish Diving Gear to allow swimming and providing light.

No new enemies appear in the ocean during Hardmode, although enemies now have a chance to drop the Pirate Map. Any Wings will let you easily surface from the ocean, and a Neptune's Shell or better will act as a permanent Flipper and Gills potion, making the ocean trivially easy to survive in.

Consider building a platform across the surface of the ocean, which will make it easier to stay at the ocean surface without falling back in. This platform will also prove useful when fighting Duke Fishron.
