If you want to achieve 100% in Assassin's Creed: Black Flag Resynced, you will need to obtain a ton of collectibles. From Song Sheets to chests to portraits to model ships, there's a lot to find throughout the Caribbean. One location you'll come across fairly late in the game is the island of Misteriosa, which is a large Mayan temple that's guarded by Spanish soldiers.

Along with the usual collectibles, this place also boasts two Mayan Stela's which you'll need to solve if you want to unlock the secret armor at Tulum. Here is where to find everything on the island so you can achieve 100% and won't need to visit it again.

All Misteriosa Collectible Locations

To find Misteriosa, you will need to head south to the region of Serranilla just northeast of the fort in a collection of islands. Similar to other locations in these higher-tier regions, there will be a couple of Spanish ships guarding the island. You'll need to dispose of them if you want to safely dock at the island and explore.

Because of this, I recommend ensuring that you have upgraded the Jackdaw enough to take on a couple of four-star ships. You can usually do a lot of burst damage by utilizing your mortar and ram attack to incapacitate a boat before it's even able to retaliate. Remember to always board these ships, as this allows you to repair the Jackdaw so you can take down the other ship guarding the island.

Once you can explore the island, expect to run into multiple Spanish soldiers as they are scattered throughout the ruins. Make sure to keep an eye out for them, as they can easily overwhelm you if you're not careful!

    The only Viewpoint on this island is located at the very top of the ruins to the north. This means you'll need to progress through the jungle and then scale the large wall to reach the small temple. Once you get there, kill the Spanish soldiers hanging about and climb onto the bent tree to the right of the temple. This will be your Viewpoint and provide you with a quick way back down.

    Now make your way up the hill and kill the soldiers along the way. Climb up the first section of the wall until you reach an area with more guards and one in a tower. Deal with the enemies and then look on the right for a section of wall with multiple square doorways. Inside the farthest one, on the right, you'll find the chest inside.

Secret Locations

    As for the Secrets, you can find the Message in the Bottle on the beach to the west. Look for two palm trees near the water and approach them to find the bottle in the sand right by the water. This one can be a bit tricky to find, so keep an eye out for the small white circle that indicates where the bottle is buried.

    The second Secret can actually be found while you're scaling the wall via jumping on different beams and stone figureheads. Halfway into this climbing section, you'll reach a section with a small lower level you can get to by jumping down instead of across. There will be a skeleton lying on the floor that you can interact with to collect a Treasure Map.

    You can find the last secret at the very top of the Mayan Ruins where there is water pouring out of the stone snake figurehead. Look for a small temple next to the Viewpoint and go inside. The Secret chest is located on the right when you enter and is a manuscript. You can also find the Capuchin Monkey by the water in a tree.

  • Mayan Stele 1 Location — 265,171

    Mayan Stele number one is located right after you defeat the Spanish soldiers after you climb the first wall. Head over to the stone tower where the sniper was and follow the path down to the east. There will be one more guard below you, so make sure to kill him before running to the Mayan Stele near the water. Rotate the symbols on the ground until they line up with the snake heads and pillars along the wall. This one is a bit finicky to get lined up, so it may take a couple tries.

    The last Mayan Stele (and collectible) on Misteriosa can be found when you're climbing the wall up to the top. After you get the Treasure Map, continue along the jumping path until you reach a raised section with the Mayan Stele podium. Climb onto the podium and align the symbols with the three giant rocks at the base of the island.
