Mysterious Coral Vessel

The Mysterious Coral Vessel is an undersea, coral encrusted variant of the Mysterious Vessel Artefact which can be discovered throughout Siren Shrines or within the vaults of Siren Treasuries.

Where to find

Mysterious Coral Vessels can be found from the following sources:

Chance to find throughout Siren Shrines.
Chance to find inside the vault of a Siren Treasury after defeating the Treasury Vaultmaster. Can be either out in the open or inside a Coral Treasure Chest.

To save pirates from needing to take their treasure all the way back up the the surface, up to 20 loot pieces can be stored in Sunken Mermaid Statues found along the way. Any treasure left with the statues can be retrieved at the water's surface from a friendly mermaid with a shell, emitting purple smoke. When interacted with, any treasure collected will float up to the surface and the mermaid depart.
