Memory 01: 01 Diving For Medicines

Approach Blackbeard’s ship The Queen Anne’s Revenge in the ocean by the San Ignatio shipwreck, east of the Dry Tortuga fort.

After the starting scene, sail to the San Ignatio Wreck, dock, and use the diving bell to reach the seabed.

Loot three of the four treasure chests in the starting area. One is north of the bell, another is northwest of the first air barrel behind jellyfish, and a third is north of that inside a ship hull section.

Approach the glowing hatch on the main deck of the ship and interact with it to enter the ship.

Loot the chest inside the ship.

Follow the tunnel until you reach an air pocket. Surface to replenish air.

Continue through the tunnel to a cave with a strong current. Work your way towards the northern exit.

Use the air barrel in front of the exit to resupply oxygen.

Enter the wreck to your right to find an Animus Fragment.

Swim right from the back of this wreck to find another wreck.

On a rock platform in front of this wreck, behind seaweed, find a chest.

Return to the chest you ignored earlier and open it.

Swim to the Animus Fragment in the distance and grab it.

Enter the wreck to its left to find the final chest, containing a Plan – Elite Hull Upgrade for the Jackdaw.

Head for the diving bell marked with the green objective marker and interact with it to complete the mission.
