AC4 Naval Battle for Metal. Jackdaw upgrades - Elite Mortar, Elite broad...

Now my Jackdaw is ready for the Legendary fights!
To have enough money is not enough to upgrade your Jackdaw to the maximum Elite level. While you will also need cloth and wood, but metal is what you really need the most. Elite upgrades of Mortar and Broadside cannons require 650 crates of metal each! You should do a lot of Naval Battles targeting ships carrying metal.
Enjoy my battle for the metal!
