Mastering the Seas: A Complete Guide to Finding All 12 Elite Ship Upgrades in Assassin's Creed Black Flag Resynced

Thirteen years after the original pirate adventure captured our imaginations, Assassin's Creed Black Flag Resynced brings the legendary Jackdaw back to the high seas with modernized visuals and gameplay. To truly dominate the Caribbean, you must transform the Jackdaw from a humble vessel into an unstoppable warship. Achieving this requires finding all 12 elusive elite ship upgrades. Here is your essential guide to securing these powerful modifications.

Preparing for Your Search

Before embarking on your hunt for these blueprints, remember that you cannot simply sail to them. Many are locked behind specific mechanics:

• Treasure Maps: Several blueprints are found by deciphering treasure maps found throughout the world.
• The Diving Bell: Essential for underwater wrecks, this item is unlocked during the 'Diving for Medicine' mission. Ensure you have 5,000 Reales saved, as it is a required investment.

Once a blueprint is acquired, you must visit a Harbor Master in any major port to apply the upgrade to your vessel using the necessary materials and currency.
