Assassins Creed Black Flag Resynced Blackbeard's Treasure

Blackbeard's treasure is an exclusive side quest reward hidden inside the flooded cavern of Anotto Bay at coordinates 590, 245. Completing the underwater path and explosive barrel barriers awards agricultural supplies for Great Inagua alongside Blackbeard's decorative portrait.

Where Is Blackbeard's Treasure Located?

Anotto Bay is an underwater cave system positioned north of Kingston at coordinates 590, 245. The quest unlocks automatically after you finish the Sequence 8 story mission, Do Not Go Gently. Following that storyline sequence, Edward Kenway examines Edward Thatch's hat on the beach, adding the sea shanty Burn Blackbeard's Beard and Blackbeard's Treasure Map to your inventory codex database.

Hostile ships defend the exterior waters of Anotto Bay. When the Jackdaw sails toward the marker, three brigs and one frigate block your approach. You must sink these vessels before dropping anchor at the docking zone. Having prepared jackdaw upgrades, particularly level 3 mortars, allows you to disable the smaller brigs from long range before entering direct cannon trades.

After docking, swim to the exterior wooden platforms. A note attached to a support pillar confirms that smugglers attempted to enter the submerged cave using a diving bell before the suspension rope snapped. Rather than using an operational diving bell, Kenway dives directly into the open water near the sunken bell. Swim down past the hanging jellyfish, replenish oxygen at the bubble columns, and enter the flooded mine tunnel leading into the cavern interior.

How Do You Clear the Cave and Barrel Obstacles?

Explosive powder kegs are the core requirement for clearing blocked passages throughout Anotto Bay. The interior features two sealed walls that require manual demolition before you reach the central loot chamber.

1. Swim through the main tunnel while staying clear of the sea urchins. If you turn into the optional left side passage for a secondary chest, dodge the attacking shark before swimming to the surface air pocket.
2. Emerge onto the dry platform where six smugglers patrol. Eliminate the sentries with aerial strikes or stealth takedowns.
3. Pick up a red powder keg from the supply stack near the edge of the gap.
4. Carry the barrel to the collapsed stone barrier across the room, set it down, step away to a safe distance, and shoot the barrel with your pistol to blast the path open.
5. Move through the newly opened tunnel to enter the main cavern, where you face Blackbeard's former sailing master, Israel Hands, along with his surviving crew.
6. Defeat Israel Hands in sword combat, then take another powder keg from the supplies near the central campsite firepit.
7. Carry this second keg up the rocky incline to the right of the waterfall, set it down against the rock rubble, and detonate it with your firearm.

A rare collision glitch documented on the Steam community forums occurs if players detonate the large central barrel in the first chamber prematurely, destroying the smaller kegs before the doorway is cleared. Quitting to the main menu and reloading the cave checkpoint immediately respawns the required powder kegs. As described in IGN's quest walkthrough, clearing the final rubble behind the waterfall triggers the story chest sequence.

What Are the Rewards for Completing the Quest?

The final reward is Blackbeard's Portrait, which Edward Kenway hangs in the Great Inagua manor basement. Opening the chest behind the waterfall reveals no gold coins or jewels. Instead, Kenway discovers agricultural tools, plows, pitchforks, crop seeds, and a farming manual, along with a personal farewell note written by Thatch.

To conclude the quest, fast travel back to your hideout on Great Inagua. Approach the green objective marker located behind the General Store and interact with the supply chest. A cutscene triggers showing a two-month time skip, during which Kenway and the manor butler convert the island soil into working farmland.

Once the time skip cutscene ends, enter the Great Inagua manor house, descend the stone stairs toward the basement, and interact with the wall display slot on the left corridor to mount the portrait. Completing this storyline marks the quest finished in your log, complementing other treasure maps and adding a piece to your estate art collection. Technical details and system configurations for running the remake are cataloged on the Steam store page.
