Bigger ships take ye to larger islands. Starting from Schooner, ye can travel to pirate locations with Treasure Troves that hold additional valuables. The main goal of expeditions remains the same: ye still need to find and open the Dead Man's Chest. In contrast to DMC, Treasure Troves are truly hidden. To make it easier to find the Dead Man's Chest, Treasury and Levers, complete the tasks of the Pirate Pass, level up the Pirate Pass level to unlock hints (with the Golden Compass, hints are activated immediately!).
