After defeating Blaaz, return to Mercay Island and speak with Oshus. He will instruct you on how to find the Ghost Ship. The Ghost Ship appears in a specific quadrant of the sea, but its exact location changes. You'll need to use the sea chart and listen to rumors from various characters to pinpoint its whereabouts. Often, characters on islands will give you clues about where the Ghost Ship was last seen. Once you have a general idea, sail to that area. The Ghost Ship is shrouded in fog and will often disappear if you get too close too quickly. The trick is to approach it slowly and carefully. When you spot it, try to get close enough to board it. This might take a few attempts, as it's a bit of a chase sequence. Once you successfully board the Ghost Ship, be prepared for a unique dungeon experience. The Ghost Ship is not a traditional dungeon; it's more of a puzzle-filled environment where you'll need to find a specific item or character to progress.
