Are you seriously ready to find out which specific waterfall cave hides the massive Elite Mortar Storage blueprint, how to safely navigate the shark-infested trenches of the Blue Hole to double your Broadside Cannons, and the exact coordinates to dig up the game-changing Elite Hull Armor plan that completely breaks the physics of naval combat? Stop getting boarded like a rookie and max out your battleship right now before the endgame bosses sink your save file forever! 👇🔥

The naval warfare ecosystem of Assassin’s Creed Black Flag Resynced has reached a boiling point this week as players shift their focus from land-based grinding to absolute maritime dominance. Specialized subreddits and high-tier Discord groups are currently filled with coordination maps as players scramble to secure the 12 Elite Ship Upgrades required to max out the Jackdaw.
Without these ultimate plans, veteran captains warn that progressing into late-game sectors or surviving encounters with the game’s notorious Legendary Ships is statistically impossible.
The Two-Step Treasure Map Meta: Mortar and Fire Barrel Storage
The most significant hurdle identified by the community involves the intricate, two-step acquisition process for several core upgrades. Unlike standard gear, these top-tier blueprints cannot simply be purchased; they require players to hunt down specific treasure maps before navigating to entirely separate coordinates to excavate the physical chests.
According to technical analysis popularized by veteran gaming guide creator Gaming with Griff Griffin, the layout requires precise navigation:
Elite Mortar Storage: The process begins at Tortuga, where players must secure a localized treasure map. The coordinates point directly to Matanzas. Hardcore players are optimizing this run by pushing through the jungle path, following the natural running water channels, and passing directly behind a hidden waterfall to dig up the plan, which additionally yields a massive 3,000 Reales bonus cache.
Elite Fire Barrel Storage: Acquired by first looting a map hidden inside the treacherous Petite Cavern. The map provides explicit vector coordinates leading to the ancient ruins of Tulum. Players are utilizing the Tulum viewpoint to execute a high-altitude dive directly into the water channels below to excavate the plan, which drastically increases the rear-deployable explosive capacity of the ship.
Elite Heavy Shot Storage: Sourced via a treasure map located at Cayman Sound. The internal codec coordinates (863, 235) force players to backtrack directly into the Petite Cavern, utilizing the fast-travel mechanics to spawn near the cavern’s primary internal waterfall node to dig up the chest.
The Sequence 6 Diving Bell Gatekeeper
A major point of friction within the community centers on the technical progression wall surrounding the underwater upgrades. Forums are flooded with complaints from early-game players who are attempting to sail directly to deep-sea coordinates, only to realize that the most powerful naval upgrades are strictly locked behind Sequence 6, Memory 1 (the narrative mission titled Diving for Medicines).
Clearing this mission unlocks the Diving Bell mechanic, a vital tool that introduces complex underwater physics, localized oxygen management, and shark-evasion loops across high-yield maritime crash sites.
The deep-sea layout includes three of the most powerful offensive and defensive blueprints in the game:
Elite Mortar Strength: Located deep within the Atocha Wreck. Players must navigate Edward Kenway through sunken hulls while dodging environmental hazards to identify a distinctly larger, high-tier chest asset containing the ultimate mortar damage scaling plan.
Elite Fire Barrel Strength: This plan requires players to secure a map at Santaneillas (coordinates 455, 462) which routes them into the flooded caverns of San Juan. Navigating this cave system introduces intense survival tension; players are sharing tips online to follow the tracking paths of glowing jellyfish assets to locate subterranean air pockets to avoid drowning before reaching the dig site.
Elite Heavy Shot Strength: Found by combining a map from Ambergris Key (often referred to by community members as “Whalesick Key”) with an excavation spot located directly in a patch of brush adjacent to the primary viewpoint at Mysteriosa.
Deep Sea Trenches: Broadside Cannons and Hull Armor
The absolute apex of the Jackdaw’s combat scaling relies on three highly lethal upgrades found within the deepest oceanic trenches of the Resynced engine.
The first is the Elite Battering Ram, recovered from the Conception Wreck located in the far northeastern quadrant of the world map. This blueprint completely alters naval ramming physics, allowing a maxed-out Jackdaw to crack mid-tier enemy frigates completely in half on a single impact vector.
The second highly sought-after combat asset is the Elite Broadside Cannons upgrade, resting at the floor of the Blue Hole. The Blue Hole has quickly become a fan-favorite diving location on TikTok due to its hyper-realistic light refraction and dense concentration of hidden gold caches, yielding upwards of 10,000 Reales in secondary loot. The Elite chest itself adds physical physical cannon models to the flanks of the ship, drastically increasing volley density.
The final two structural upgrades round out the ship’s survivability:
Elite Swivel Guns: Obscured within the labyrinthine Devil’s Eye Caverns. This cave system is notoriously difficult to navigate as it features zero underwater air barrels, forcing players to perfectly map out their swimming lines to locate the chest asset.
Elite Roundshot Strength: Tucked away in the submerged Kabah Ruins, a structurally striking zone heavily inspired by ancient Mayan architecture.
Elite Hull Armor: The absolute holy grail of ship defense, located at San Ignacio (coordinates 348, 745). Because this sector is integrated directly into the mandatory Sequence 6 storyline, veteran players warn that missing the chest during the initial narrative run forces a highly tedious return trip to dodge aggressive shark AI patrols just to recover the hull plans.
Looking Forward: The Legendary Showdown
As hundreds of thousands of digital captains max out their ship stats using these exact coordinates, the Assassin’s Creed Black Flag Resynced meta is transitioning into its final phase: the hunting of the legendary automated battleships patrolling the edges of the map. With the Elite Hull Armor cushioning massive impacts and the Elite Broadside Cannons outputting unprecedented damage, the community has turned what was once a terrifying endgame challenge into a highly calculated science, proving that in the modern era of gaming, the right blueprint path makes all the difference between a sunken wreck and a ruler of the sea.
