Guide:Surviving in the Ocean

=Getting Started= To survive in the Ocean, you need one main item: the Gills Potion. To make the Gills Potion, you will need to take 1 Bottled Water, 1 Waterleaf and 1 Coral to an Alchemy Station. Alternatively, you can equip a Neptune's Shell. (You can only get a Neptune's Shell in Hardmode.)

=Notes=
 * It is recommended that you take at least 3 Gills Potions with you when venturing into the Ocean, as it is easy to get caught out of breath.
 * You can build a rope column up to the surface and use it to quickly ascend for breath. If you are wearing the Diving Helmet you should have enough time to access the deepest part of the ocean and make a rope column to the surface.

Optional Items
Note: Although these items are optional, they are recommended and prove to be very useful.
 * Glowstick
 * Breathing Reed
 * Any Hammer, Meteor Hamaxe or Molten Hamaxe
 * A decent hand held weapon
 * Healing Potion
 * Flipper
 * Diving Helmet
 * Magic Mirror
 * Gills Potion
 * Rope

Chests
Chests are fairly common in the Oceans. They mainly contain loot having to do with water, like Breathing Reed and Flipper. The Ocean chests also contain general loot that can be found in most other chests around the world; things like Gold Coins and Dynamite.

Note: Although all Ocean chests spawn in the Ocean, most spawn off the edge of the map making them impossible to reach.

Getting There
In all worlds, there are two Oceans, one at either side of the map. The Oceans don't really play a very big part in-game; they are mainly used for the Coral to make the Gills Potion paired with the Obsidian Skin Potion to make adventuring into The Underworld safer.

What is there to do there?
Once you have gotten to either of the Oceans, you can do a few things. '''Note: If you are going to be looting chests then you should get all of your speed boost items on, take a Magic Mirror and run to one of the Oceans. Then when you have done that one, use the Magic Mirror to save yourself a journey back.'''
 * 1) Harvest Coral.
 * 2) Kill the sharks for shark fins and the diving helmet.
 * 3) Loot the chests.
 * 4) Make an underwater home away from home. Underwater home.png
 * 5) Collect water in Buckets to grow and harvest waterleaf or make Obsidian.
