AC4 Black Flag Elite Design Plan Locations Guide

Elite Design Plans are the highest level upgrade for your Jackdaw. In order to acquire all plans, you should visit many Caribbean Islands, as well as complete the story mission “Diving for Medicines“.
This mission rewards you with Diving Bell upgrade, which helps you reach the bottom of the ocean.

      Where are the cadavers for the elite hull sand elite broadside canons?????

        A
        Austin

        there are no cadavers for them they are in chests at the wrecks

          I don’t have the map for the dig location of Elite Fire Barrel Storage, the cadaver is missing the map somehow, the Arroyos tavern owner won’t give me ANY information, and I can’t dig at the dig site. What’s going on? It’s like Elite Fire Barrel Storage was removed from the game, but it still says I need that plan for that upgrade.

            To get the Elite Fire Barrel Storage upgrade, you’d first have to build your fleet of ships. Kenway’s Fleet is a minigame only playable online. So sign-in to your Xbox Live or PSN account and look for the mission “Scarlatina”. After retrieving the treasure map, head to Isla Providencia for the dig-up and acquisition of the plan.

        They’re up the top, you need to dive and search for chests underwater, the plan for the elite hull is in the chest furthest in the back of the map underwater if that helps.

      how to win without firing a single cannon

      yes they were. if you want to know something else useful I found out that if you somehow get onto an enemy ship and kill every one on board a single broadside will immediately defeat the ship and when you board there won’t be any enemies to fight. The way I get aboard ships is a: if it is not moving just swim to it BEWARE IT WILL SHOOT ITS CANNONS AT YOU IF YOUR SWIMMING TOWRADS IT DIVE AND ONLY SURFACE FOR A SECOND AFTER IT FIRES. Or b: if its moving try to get it stuck between you and an island or pull up alongside it get ahead of it a little and get off the wheel as quick as possible and jump over onto the ship. If you did it right after you get off the ship it should look like it was hit by cannons WARNING IF EVEN ONE PERSON IS ALIVE IT WONT WORK. if you want to say something about this just reply my email does not work. with this method I could take on men of war with out any upgrades.

    what do these plans do? without these plans i can still upgrade and get the final upgrade. do they boost the stats if i buy the final upgrade when i have the plans?

      L
      Lokesh

      These plans are prerequisite plans for the final upgrade. You can not buy the final upgrade without them.

        B

        The are a prerequisite if you do not buy the dlc that makes it otherwise

    can someone pease explain why the coordinates for the cadaver of the elite mortar storage are on an inaccessable island?

      M
      Matt

      I figured it out, there’s a typo in the coordinates, its supposed to be (882,377), if anyone else had an issue

    The coordinates for the the mortars are not correct. The plans gave me Aqulia’s Wheel, not the mortars. Does anyone have a correction or is it my game that the coordinates(630,660) are not for Mortars

      L
      Lokesh

      Hmm, you can check the location where others acquired the Aqulia’s Wheel, maybe you were rewarded with Mortars here instead. In order to reach the dig location on Pinos Isle (335,480), grab the treasure map at Cumberland Bay (679,371). It is number 8 at our Assassin’s Creed 4 Treasure Map Locations Guide.

    For all the guys who complained about not finding the right treasure, the game literally tells you what you’re going to get from the treasure chest the map leads you to right up above the map. Just letting you know that there’s a quick way to validate these incredibly helpful tips (unless they’re wrong, then it’s not so helpful :P).

      You need to do the fleet mission done with either the in-app companion or in the captains cabin. You cannot find it regularly
