Players can find the Blurry Sketch of the Island curio at a shipwreck on the east coast of the island, which marks the treasure's location on their map. The treasure is buried in the center of a circle of skeletons, indicated by a star icon, and requires a shovel to dig it up. Upon opening the chest, players will encounter four drowned level 2 enemies that must be defeated to access the chest's contents, which include experience points, silver ingots, and guineas. After securing the treasure, players can acquire their first ship and utilize fast travel between islands as they collect more curios.
