Assassin’s Creed IV: Black Flag Misteriosa Secrets Locations
Secret 1: Letter
On Misteriosa you can also find two secrets. The first one is a letter (My Apprentyceship), inside a bottle, on the eastern beach.
The bottle is on the ground between the water and a palm tree.
Secret 2: Cadaver
The second secret is a cadaver that carries a treasure map. The AC4 Misteriosa treasure map points to the location of a buried chest that can be found in Kingston. First, look for the treasure map in the tunnel below the first Animus Fragment.
After you get the map, open it and you will see two coordinates: 623,127. The Misteriosa map also features two drawings. On the left side of the map you can see the gulf in Kingston, while on the right side is the exact location of the buried chest.
Travel to Kingston and you will notice that the area is separated in two parts (north and south), by the gulf that appears on the treasure map. On the eastern side of the gulf, is a rowboat and next to it a shipwreck.
Walk around the shipwreck looking for several crates. Between them is a patch of dirt and the digging spot.
Dig to retrieve the buried chest in Kingston and inside you will find 3000 Reales and the design plans for the Blackwood Wheel.
