The treasure count is clear, even if every guide does not count it the same way
Assassin’s Creed 4: Black Flag Resynced has 30 Treasure Maps according to IGN, PowerPyx, and GameSpot, and that number is the safest starting point for anyone plotting a full Caribbean sweep. The tension for returning pirates is that the hunt is no longer a simple memory of skeletons on beaches and X-marks-the-spot sketches. GameSpot reports that Resynced has the usual Treasure Maps found on cadavers, along with Map Pieces that can be restored through the Treasure Dealer shop in Great Inagua. PowerPyx adds a practical wrinkle: each map can have two names, one based on where it is found in your inventory and another based on the buried treasure location in the Codex. That is exactly the kind of detail that can send a veteran captain sailing in circles if they are relying on old route memory instead of coordinates. There is also one source conflict worth flagging. A provided PC Gamer listing is titled around 26 Black Flag Resynced treasure map locations, while IGN, PowerPyx, and GameSpot all state there are 30. The PC Gamer excerpt does not provide enough detail to explain the difference, so this guide treats 30 as the better-supported figure while focusing on the major rewards and coordinates confirmed in the supplied material.
How Resynced treasure maps work before you start sailing
GameSpot’s guide states the key rule: you can only dig up a buried chest once the relevant Treasure Map is in your Codex. In practical terms, do not rush to a famous coordinate and expect Edward to claw gold out of the sand unless you have first collected the map or restored the relevant piece. The confirmed acquisition methods are varied. GamingBolt lists maps found on skeletons under palm trees, inside caves, in tunnels, on shorelines, at the bottom of Havana’s canal, and during the “Smelly Sailors” local event. GameSpot also lists warehouse sources, including Nassau Warehouse, which requires finding the key and plundering the warehouse before chasing its buried chest. PowerPyx gives the best route-management advice from the supplied sources: sail to locations first to unlock fast travel, expect a few locations to be story-gated, and know that nothing is missable because everything can still be found in free-roam after the story. One confirmed story-linked case is Blackbeard’s Treasure Map, which GamingBolt says is granted automatically after completing “Do Not Go Gently…” and leads to a buried chest at Anotto Bay in Charlotte at 591,243. That last example is a good reminder that Resynced’s treasure system is still tied to Black Flag’s pacing. Some prizes sit out in the open world waiting for a clean approach, while others are gated behind a quest, a warehouse, or the game’s restored-map economy.
The fastest high-value ship route: plans, sails, wheels, and weapons
If your priority is making the Jackdaw hit harder and look sharper, start with the treasure maps that lead to Ultimate Plans and named ship cosmetics. GameSpot places the Great Inagua map at 813,448, inside a tunnel reached by following the sloping path from the docks and mantling up ledges. Its buried chest is in Nassau at 586,755, past the manor near a large rock formation and a tree, and the reward is the Elite Sails Design Plan plus 3,000 reales. GamingBolt lists the Havana map on a skeleton at the bottom of the canal at 217,571, with its chest also in Havana at 213,564, rewarding The Queen Anne’s Figurehead Design Plan and 3,000 reales. For firepower, GamingBolt lists the Ambergris Key map in Chinchorro at 27,159, on a skeleton inside the tunnel system. Its chest is at Misteriosa, 271,178, and contains the Heavy Shot Strength Ultimate Plan and 3,000 reales. The Cayman Sound map is on the north-west shoreline of Cayman Sound in Castillo de Jagua at 297,314, with the buried chest at Petite Caverne, 863,235, rewarding the Heavy Shot Storage Ultimate Plan and 3,000 reales. GameSpot adds another major upgrade path: the Mariguana Island map at 847,514, found near a central rock formation behind vines, points to Andreas Island at 544,693 and rewards the Harpoon Strength Ultimate Plan and 3,000 reales. For presentation rather than damage, GamingBolt lists the Cumberland Bay map along the southern shoreline in Punta Guarico at 648,345. Its chest is on Pinos Isle at 304,455 and contains the Ivory Wheel Design Plan plus 3,000 reales. These are the AC Black Flag Resynced treasure locations to prioritize if you want visible ship gains and a healthier purse before cleaning up lower-value chests.
Outfits, art, trinkets, and the rewards that mostly pay the bills
The outfit route is shorter, but it is the one most likely to pull returning players off a straight upgrade path. GamingBolt lists the Corozal map on a tiny island in Chinchorro at 12,242, where a skeleton is propped beside a campfire. Its buried chest is at Ambergris Key, 30,157, and rewards the Pirate Captain Outfit plus 2,000 reales. GameSpot lists the Nassau Warehouse map at 593,750; after plundering the warehouse, its chest is at Isla Providencia, 487,11, underneath a tree to the left of a wrecked boat, and the reward is the Governor’s Outfit plus 2,000 reales. Some treasures matter less for combat and more for completion. GamingBolt lists the Andreas Island map at 543,693, beneath twin palm trees near a shipwreck, with a chest on Abaco Island at 586,811 that rewards the Earth Monster Relief and 2,500 reales. GameSpot lists the Salt Lagoon map at 723,608 on a cadaver washed up on the beach, pointing to New Bone, 407,94, where the chest rewards the Maize Deity and 2,500 reales. The Abaco Island map, according to GamingBolt, is under a palm tree at 580,804 and points to Salt Lagoon, 719,607, rewarding the Serpent Figurehead and 3,000 reales. Smaller stops still add up. Cape Bonavista’s map is in a small cave at 160,580 and points to a shallow pool at 146,587 for 1,500 reales, while the Map of Shipwreck is on a crate during the “Smelly Sailors” local event at Havana, 226,573, and leads to underwater chests in Dry Tortuga at 357,700 with the Guardian Beast Trinket and 1,000 reales. PowerPyx says trophy and achievement hunters only need the treasures tied to six Ultimate Plans, three Art Pieces, and one Portrait; the rest are valuable for money, cosmetics, and completion rather than being required for that specific trophy path.
The Treasure Dealer makes money and bones part of the same voyage
The biggest Resynced-specific planning change in the supplied sources is the Treasure Dealer. GameSpot says Map Pieces can be restored through the Treasure Dealer shop in Great Inagua, which means a full Assassins Creed Black Flag Resynced treasure maps run is partly about world discovery and partly about using a shop system correctly. NintendoSmash adds another reason to keep Great Inagua in your route: the Treasure Dealer there sells bones for 1,000 reales each, and bones are needed for one of Resynced’s standout crew cosmetics. According to NintendoSmash, the Deceased Crew Attire, the Skeleton Crew cosmetic, costs 206 bones and is sold by a vendor on an unnamed island at 550,638, northwest of the Gibara region. The same outlet says bones can be farmed from animals by fast traveling between islands and passing time to respawn them, or bought from the Great Inagua Treasure Dealer, who restocks bones frequently. This is where treasure chests become more than a checklist item in practice, even though the rewards themselves are fixed. A 3,000-real chest is a direct push toward ship upgrades, outfit shopping, or the costly bone exchange if you want the Skeleton Crew. NintendoSmash also reports that Resynced includes Stede Bonnet’s Attire as a legendary outfit found in a secret chest on Mystery Island at 913,123, with related Revenge Sails and Revenge Figurehead chests at 910,122 and 907,126. That outfit has no perks, according to the outlet, but it underlines the same point: Resynced’s Caribbean puts a heavier spotlight on appearance, and treasure money helps you engage with that layer faster.
A clean sailing order for returning pirates
For a focused Black Flag Resynced guide route, do not try to sweep the whole sea in a spiral unless you already have most viewpoints and docks unlocked. Start at Great Inagua because it serves three purposes in the supplied sources: it has a treasure map leading to Elite Sails, it houses the Treasure Dealer tied to restored Map Pieces, and it becomes a useful stop if you decide to buy bones for the Skeleton Crew. From there, cash in the Great Inagua-to-Nassau chest, then fold in Nassau Warehouse if you have the key and want the Governor’s Outfit. Move through Havana for The Queen Anne’s Figurehead Design Plan and the Shipwreck local-event reward, then hit Cape Bonavista for an easy same-zone cash chest. After that, push into Eleuthera and nearby northern stops for Mariguana’s Harpoon Strength Ultimate Plan, Andreas Island’s Earth Monster Relief, and Abaco’s Serpent Figurehead. Save the more scattered southern and western runs for when fast travel is open: Ambergris Key to Misteriosa for Heavy Shot Strength, Cayman Sound to Petite Caverne for Heavy Shot Storage, Corozal back to Ambergris for the Pirate Captain Outfit, and Cumberland Bay to Pinos Isle for the Ivory Wheel. IGN’s Resynced interactive map can help with cleanup because its listed filters include Treasure Maps, shops, equipment, quests, and other collectible categories, but the key discipline is simpler: collect the map first, verify whether your inventory name and Codex name differ, then sail to the chest coordinate. That rhythm keeps the hunt moving like Black Flag at its best, a hard cut from dockside clue to open-water pursuit to the quiet pause before Edward digs up another piece of the Jackdaw’s legend.
