Obtain a Deep Sea’s Treasure Map

There is a very rare chance a Deep Sea’s Treasure Map will drop, when you use a key from Sailing Co-ops, after participating in a Sailing Gate.

Each Sailing Co-op has a specific key that it can drop.

The easist beginner key to obtain is Key of Harmony, obtained by participating in any of the 3 missions within Sailing Co-op events for Vern, Arthetine, and Anikka.

Use Deep Sea Hidden Treasure

RMB the Deep Sea’s Hidden Treasure in your inventory.

It will show the location of the treasure.

TIP: the text will change on the treasure map as you move, indicating how close you are. When you are very close, it will start to give you more precise directions.

Finding the Treasure Location

Look for an icon on the water that looks like a green diving suit helmet.

After you interact with the diving helmet icon, a video will play to show you the progress of your treasure dive.

The further down he dives, the more rewards you obtain.

You have no control over how far the diver swims. It’s all RNG.
