Coral Seafarer's Chest

The Coral Seafarer's Chest is an undersea, coral encrusted variant of the standard Seafarer's Chest, which can be discovered throughout Siren Shrines or within the vaults of Siren Treasuries.

Where to find

Coral Seafarer's Chests 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.

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.

Rewards

Coral Seafarer's Chests can be sold to:

Hoarders stationed at Gold Hoarders tents on Outposts for Gold and Gold Hoarders Reputation and Emissary Value (if sailing as a Gold Hoarders Emissary)
The Servant of the Flame at The Reaper’s Hideout for Gold and Reaper's Bones Reputation and Emissary Value (if sailing as a Reaper's Bones Emissary)
The Sovereigns at the Sovereigns Hut on Outposts for Gold and Gold Hoarders Reputation and Emissary Value (if sailing as a Gold Hoarders Emissary)
