Sunken Curse is the third Bilge Rats Adventure. This post will be updated with information and a guide after it's released.
Speak to a Bilge Rats NPC for an introduction, or simply open up the reputations screen and click on Bilge Rats to view the latest commendations.
Mermaid statues are located underwater around many islands. Sometimes they are close to the shore, other times they are deeper under the water.
The mermaid statues spawn randomly.
You'll be able to hear some ominous music and see them glinting in the distance when you are underwater (similar to messages in bottles).
You need to destroy the statue. Sapphire statues are easy to break, the other colours require more work and a crew to break. After it breaks your commendation progress will increase (there is no other reward).
There are 150 Doubloons available for this event if you complete all commendations, including the legendary commendations.
