The “Enrage” Mechanic Breaking Pirates: How to Finally Sink the Royal Sovereign & HMS Fearless in ‘Black Flag Resynced’

🚨 The Black Flag Resynced community is getting absolutely DESTROYED by the Royal Sovereign & HMS Fearless because of ONE massive, game-ending mistake. 🤯

Players are just realizing that focusing all your fire on one ship actually triggers a hidden “enrage” mechanic, turning the surviving Man O’ War into an unstoppable, rapid-firing nightmare! Plus, if you aren’t using the secret artillery hidden behind a specific officer on Great Inagua, your cannons are basically useless.

Stop sinking your Jackdaw and discover the ONLY foolproof strategy to conquer the Caribbean’s deadliest dual-boss fight. 👇🔥

For over a month, Assassin’s Creed Black Flag Resynced has allowed players to live out their ultimate pirate fantasies. With an overhauled naval combat engine, stunningly realistic water physics, and a deeply customizable Jackdaw, ruling the Caribbean has never felt more immersive. However, in the deepest, most dangerous corners of the map, a dual-threat is forcing even the most seasoned captains to rage-quit: The Legendary Ships, HMS Fearless and Royal Sovereign.

In the original 2013 game, these twin Man O’ War vessels were notorious for their brutal difficulty. In the Resynced edition, Ubisoft has dramatically turned up the dial. These two behemoths do not just hit harder; they hunt with a terrifying, coordinated AI that actively punishes traditional gaming strategies. Across Reddit, Discord, and X (formerly Twitter), players are trading horror stories of their fully upgraded ships being reduced to splinters in mere seconds.

However, thanks to top-tier players and dedicated community testing, the ultimate strategy to defeat both ships has finally been cracked. It involves secret weaponry, rigorous preparation, and avoiding a massive psychological trap that 99% of players fall into. Here is the definitive, community-tested guide to surviving the deadliest naval battle in Black Flag Resynced.

The Ultimate Trap: Do Not Trigger the “Enrage” Phase In almost every video game featuring a dual-boss encounter, the standard strategy is universal: focus all your damage on one target to quickly remove it from the board, then slowly whittle down the survivor. If you attempt this strategy against the Royal Sovereign and HMS Fearless, you are guaranteeing your own watery grave.

Ubisoft secretly implemented a brutal mechanic that the community is dubbing the “Enrage Phase.” If a player successfully sinks one of the two legendary ships while the other still has a significant amount of health, the surviving ship will immediately alter its attack pattern.

“I thought I had it in the bag,” explained a frustrated user in a viral TikTok video that has amassed over 3 million views. “I sunk the Fearless, and suddenly the Sovereign completely broke the laws of physics. It started attacking continuously from multiple directions without pausing to reload. It was like fighting a machine gun on water.”

This is the biggest mistake players are making. The surviving ship becomes hyper-aggressive, relentlessly ramming and bombarding the Jackdaw with a barrage that is nearly impossible to survive. The key to this fight is extreme patience and precise damage management. You must lower the health bars of both ships simultaneously. The goal is to keep their damage levels roughly identical, ensuring that when one finally goes down, the other is only one or two cannon volleys away from destruction, giving the enraged survivor no time to unleash its devastating final form.

The Secret Weapon: The Deadman’s Cohort Mortar Managing the health of two highly aggressive Man O’ Wars requires heavy artillery. Standard mortars in Resynced have a major flaw during this specific fight: they take too long to land. Because the Fearless and Sovereign move with aggressive, unnatural speed, standard mortar shots often splash harmlessly into the ocean as the legendary ships sail right past the blast zone.

To win this fight easily, the community has discovered that players must seek out a very specific, unlisted weapon upgrade: the Deadman’s Cohort Mortar.

Unlocking this devastating weapon is a journey in itself. First, players must unlock the “Dead Man” officer for their crew. Once this specific officer is stationed on your ship, an exclusive “Dead Man’s Quest Line” will become available on Great Inagua Island. Completing this side-story rewards players with the Deadman’s Cohort Mortar.

Why is this mortar so essential? It dramatically alters the weapon’s physics. The Deadman’s Mortar fires much faster, meaning the projectile reaches its target before the enemy ships can maneuver out of the blast radius. Furthermore, it deals significantly more damage than the standard fully-upgraded mortar. As one Discord guide aptly noted, “Going into the dual-boss fight without the Deadman’s Mortar is like bringing a musket to a missile fight.”

Preparation: Officers and Ultimate Plans Before even sailing into the legendary encounter zone, standard upgrades will not suffice. The Royal Sovereign and HMS Fearless will absolutely shred a ship that is only at 90% capacity.

Players must track down every single “Ultimate Plan” scattered across the Caribbean. These blueprints represent the absolute pinnacle of Jackdaw engineering, maxing out hull armor, broadside cannons, and swivel guns. Because these upgrades require vast amounts of resources, players are heavily relying on community “unlimited money farming” routes to afford the steep crafting costs.

Furthermore, Resynced places a heavy emphasis on your crew’s leadership. Players are highly advised to unlock all available officers before attempting this fight. Officers in the remake provide passive buffs that significantly improve the ship’s baseline defense and attack stats. Without these buffs, the Jackdaw simply cannot absorb the initial broadsides from the twin legendary ships.

The Dance of Death: The Perfect Combat Loop With the Deadman’s Cohort Mortar equipped, all officers aboard, and the Jackdaw fully upgraded, the battle relies entirely on positioning and execution. The legendary ships follow a specific, highly aggressive AI loop: they will chase, attempt to flank, cross the Jackdaw to unleash devastating broadsides, turn, and repeat.

To counter this, players must execute a flawless hit-and-run strategy:

The Opening Salvo: As soon as the encounter begins, both ships will typically charge. This is the moment to unleash the Deadman’s Mortar. Because they are approaching from a distance, hitting them is guaranteed, chunking a massive amount of health right out of the gate.

The Minefield Retreat: Do not charge back at them. Instead, keep the Jackdaw moving forward, constantly sailing away while continuously dropping Fire Barrels (powder barrels) directly into the water behind you. Because the legendary ships aggressively chase the player, they will consistently sail straight into this explosive wake, taking massive passive damage.

The Brace and Counter: Eventually, the ships will close the distance and cross the Jackdaw’s path to unleash their broadside cannons. This is the most critical moment of the fight. As they approach, unleash your own heavy broadside cannons. Do not admire your work—immediately hold the ‘Brace’ command. Bracing mitigates a massive percentage of incoming damage. If you fail to brace during their crossing volley, your health bar will be decimated.

The Quick-Turn Shot: As soon as the enemy volley ends and the brace is released, immediately cut the wheel hard. While turning the Jackdaw, fire the front-facing chase cannons without aiming. This rapid-fire technique scores free, guaranteed damage on the enemy’s exposed rear or side as you reposition.

Targeting the Turn: After crossing you, the legendary ships will sail a short distance away and begin a wide turn to initiate another attack run. This is their most vulnerable state. Because they are at a distance and locked into a turning animation, you must immediately target them with the Deadman’s Mortar. The faster drop-time of the secret mortar guarantees a direct hit during their turn.

Patience is the Ultimate Weapon Rinse and repeat this exact loop: Drop fire barrels while retreating, fire heavy broadsides when they close in, immediately brace, turn and use front cannons, and drop mortars while they turn around.

Throughout this entire, stressful loop, the golden rule remains: constantly alternate your targets. Check the health bars at the top of the screen meticulously. If HMS Fearless is at 30% health but the Royal Sovereign is at 60%, you must ignore the Fearless entirely and focus all broadsides and mortars onto the Sovereign until they are even again.

“It goes against every gamer instinct in my body to leave a boss at 10% health and attack the other one,” a user wrote on the r/assassinscreed subreddit. “But the moment you get greedy and finish one off, the other one turns into a speedboat with infinite cannons. You have to kill them within 30 seconds of each other.”

The Legacy of the Twin Terrors The Royal Sovereign and HMS Fearless represent the absolute pinnacle of naval combat in Assassin’s Creed Black Flag Resynced. By burying the necessary tools to defeat them behind obscure side-quests and punishing players who rely on standard gaming tropes, Ubisoft has crafted a boss fight that feels truly legendary.

For the players who manage to sink both ships, the rewards—and the immense bragging rights—are well worth the agonizing trial and error. Just remember to grab the Deadman’s Mortar, brace for impact, and whatever you do, never leave one ship alive to seek revenge.
