Assassin’s Creed 4 Black Flag Elite Design Plans Locations Guide

By   /   Nov 3, 2013

Naval combat is core to Assassin’s Creed 4. If you want to survive in the open sea, you will need a ship you can count on. A ship that cannot only survive the onslaught of pirate hunters but can also fight the legendary ships you might encounter during your adventures.

It’s tough to ask all that from your ship when you start your journey but as you progress through the game, it will become a necessity.

If you are looking to upgrade your ship to the fullest, you will need to find all the buried treasure chests and loot all the chests in underwater shipwrecks.

If you can’t locate any of these, I recommended you read our in-depth Buried Treasure Locations and Underwater Shipwrecks Locations Guides.

In total, there are 12 elite design plans you need to find in Assassin’s Creed 4. These design plans add different dimensions to your ship. For example, they may strengthen your cannons or increase mortar storage or strengthen your harpoon.
