Finding Blackbeard's Treasure in Black Flag Resynced is actually a lot tougher than the game's other treasure maps, mainly because it doesn't give you any coordinates, forcing you to rely on your knowledge of the Caribbean. This is a new quest that was added in Resynced, but you won't get it until after you complete the Do Not Go Gently main quest.
Edward finds the treasure map hidden in Blackbeard's hat, which starts the hunt, so you can't miss it. Below I'll explain where the map points to, and how to navigate the area it's contained within.
