All Antocha Wreck Treasure Chest Locations in AC Black Flag Resynced

The Antocha Wreck (600, 635) is located directly south of Nassau in the Gibara region. It’s one of the shipwrecks that Edward can explore using the Diving Bell and recover underwater treasure. The Diving Bell is unlocked after the main quest “Diving for Medicines” during Sequence 6.

The Antocha Wreck in AC Black Flag Resynced contains 8 collectible treasure chests, seven of which are regular chests containing Reales, and one of them is part of the secret collectibles, which contains the Mortar Ultimate Plan (one of the final upgrades). Let’s check out how you can get all the chests.

Antocha Wreck Chest #1 Location

The first chest is located right in front of Edward as soon as he descends into the Antocha Wreck through the Diving Bell. Simply swim forward a bit and dive to find a shipwreck. Look inside the destroyed deck below.

Antocha Wreck Chest #2 Location

The second chest is located just across the first one. Swim between the reefs ahead of you till you see the second chest inside another shipwreck.

Antocha Wreck Chest #3 Location (Secret)

Swim further south in Antocha Wreck until you come across a third shipwreck, with a larger chest sitting inside its destroyed deck.

Reward: Mortars Ultimate Plan

Antocha Wreck Chest #4 Location

Right after you open up the third chest in Antocha Wreck in Assassin’s Creed Black Flag Resynced, you’ll need to swim up to the wrecked ship’s deck. Once you get up to its deck, look below the broken boards to find the fourth treasure chest.

Antocha Wreck Chest #5 Location

Now, swim north towards the large shipwreck, and proceed to dive further down. As soon as you get past the large destroyed hull of the ship, you’ll find the fifth chest on the sea bed.

Reward: Emerald (230 Reales), Silver Bracelet (380 Reales), Gold Tiara (370 Reales)

Antocha Wreck Chest #6 Location

Getting the next chest is going to be tricky, as players will need to explore the inside of a large shipwreck right next to the previous chest. Swim up from the last chest location, and you’ll see a destroyed hull of a large ship. Swim inside the destroyed deck.

There are two entrances to the ship’s hull; take the one on the right, as the left one is boarded up. Keep swimming forward and take a U-turn to the left to head inside one of the cabins. This is where you will find the fifth treasure chest in the Antocha Wreck in AC Black Flag Resynced.

Reward: Sapphire Earrings (420 Reales), Diamond Earrings (450 Reales), Silver Bracelet (160 Reales)

Antocha Wreck Chest #7 Location

Now swim up to the ship’s top deck to get the next treasure chest in Antocha Wreck in AC Black Flag Resynced. You’ll need to head towards the middle of the staircase and inside the crew cabin.

You’ll find the seventh chest at the back of the room.

Antocha Wreck Chest #8 Location

Now, exit the ship’s cabin and swim to the northeast corner of the ship to the area I’ve marked in the image above. There’s a hole in the side of the ship’s hull that you can enter.

Inside the hull, you’ll find the eighth and last treasure chest in Antocha Wreck in Assassin’s Creed Black Flag Resynced.

Reward: Gold Tiara (370 Reales), Sapphire Earrings (420 Reales), Gold Chain (270 Reales)
