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.
Finding Sailing Events
Open the Calendar (Alt + H) then select the Sailing category.
Sailing Co-op events occur 3 times every day and Gates about every other day.
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.
