Four legendary ship battles sit in the far corners of the Caribbean in Assassin’s Creed Black Flag Resynced, and you have to sail out and find them on purpose since none of them cross the main story path. Sinking all of them is what unlocks the Devil of the Caribbean trophy, the one hard requirement blocking a Platinum run. The encounters are the same fights, in the same spots, as the original game.
Quick answer: The legendary ships are El Impoluto (115, 842), La Dama Negra (240, 72), HMS Prince (854, 55), and the paired HMS Fearless and Royal Sovereign (811, 858). Fully upgrade the Jackdaw and recruit every officer before you attack any of them.
Prepare the Jackdaw before you engage
Each legendary ship is a Man-o-War with a huge health pool and firepower that will delete an under-built Jackdaw in seconds. Going in without a maxed ship is a death sentence on Normal difficulty or higher. Max out every weapon, hull, and storage upgrade first, and top off your ammunition.
Officers matter just as much as upgrades because they unlock the abilities these fights are built around. Three of them do the heavy lifting.
| Officer | What it gives you |
|---|---|
| Lucy Baldwin | Perfect bracing, which negates most incoming damage of any type |
| The Padre | Ram Dash (L1+R1 / LB+RB) for heavy collision damage |
| Tobias Smith | An extra salvo of cannonballs |
Most officers only become available as you progress the story, so it is easiest to finish the campaign first and then hunt these ships. Remember that all naval damage can be braced, including mortars, fire barrels, and dash rams. Every legendary ship is faster than the Jackdaw and you cannot use Travel Sails to catch them, so bracing while your weapons reload is what keeps you alive through a fight of attrition.

El Impoluto (115, 842)
This Spanish Man-o-War fights hit-and-run. It charges the Jackdaw head-on with its massive ram, then sails a half-circle to sit just outside your cannon range before charging again. Beat it by copying its rhythm. When it rams, ram it back, and fire heated (burning) shot before it pulls away.
Once it opens distance, hit it with your mortar, then reset for the next charge. Each time you knock off a third of its health it sends up a flare and becomes less mobile, but it also starts firing barrages of heated shot volleys. Stay parallel to it when it charges so the ram glances off, and lean on perfect bracing to shrug off the collision damage.
La Dama Negra (240, 72)
La Dama Negra is a heavily armored Spanish Man-o-War, and its front-facing broadsides are largely ineffective against its plating. Aim your cannons at its bow or stern to actually deal damage. It leans on mortar barrages and likes to hold still while firing them, which is exactly when it is most exposed.
Stay close and pound it with heated shot broadside cannons while bracing between salvos. It has weaker broadsides than El Impoluto and fires fewer cannonballs, so tight-range trading favors you. When it breaks away to line up a mortar volley, it usually stops moving. Fire your own mortar in that window for heavy damage, and slip under its arc of fire to avoid the return barrage. This is generally the most forgiving of the four fights.
HMS Prince (854, 55)
The HMS Prince is a British Man-o-War built around a long-range mortar with a wide area of effect, and it is the trickiest to pin down. Through its three main phases it stays at close-to-medium range, mixing broadside cannons with mortar fire. Land heated shot here and brace while it reloads.
After each health segment drops, the Prince vanishes into the fog. Its icon disappears, you cannot catch it, and it spams mortar rounds for a minute or two before returning. These shots have a blast radius larger than the orange indicator, so drive in wide circles to avoid them and brace even when you think you have cleared the zone. With a perfect brace the damage is negligible. The moment it reappears, ram-dash it head-on, then close in and unload heated shot.
HMS Fearless and Royal Sovereign (811, 858)
This encounter puts two British Man-o-Wars against you at once, one with black sails and one with white, but the game treats them as a single boss fight. They move in tandem, sailing alongside each other and then turning sharply to face you together. Never let yourself drift between them, or both broadsides unload on you at the same time.
Fire your mortar when the pair makes its coordinated turn, then ram-dash one target, brace against the return fire, and hit its stern with heated shot and its red weak spots with the swivel gun. Do not chase them when they flee, since they will just throw fire barrels behind them. Let them run, then punish the next turn.
The key mechanic triggers the moment one ship sinks. The survivor gains a speed buff and switches to relentless ramming that you cannot outrun. Because each of these ships has only about half the health of the other three legendaries, try to keep both health bars low and roughly even, so once the buff kicks in you can finish the last ship quickly. After you clear a third of their combined health, they start flooding the arena with fire barrels, so use your swivel guns to pop them before they box you in.
Rewards and how to confirm the trophy
Every legendary ship sinks rather than being boarded, and each one pays out 12,000 Reales plus a miniature ship model of the vessel you just sank. The Fearless and Royal Sovereign fight gives a single combined model called Brothers in Arms instead of two. You also earn legendary cosmetics — sails, figurehead, hull, and wheel — that you can equip to the Jackdaw from the Captain’s Cabin.
Once all four battles are done, the Devil of the Caribbean silver trophy pops, confirming every legendary ship is cleared. That trophy is mandatory for the Platinum, so it doubles as your checklist. If a ship escapes to the edge of its arena and you get an out-of-area warning, break off and re-enter the fight rather than pushing past the boundary, since leaving can cost your progress.
