You'll discover a wide range of enemies and danger sailing the high seas in Assassin's Creed 4: Black Flag. The open water is full of trouble, and upgrading the Jackdaw pirate ship is the best way to ensure your safety to a degree. Problem is, doing this takes metal, and this precious resource is difficult to come by. How do you get metal in AC4? Simple, become wanted.
One of the scarcest resources in Assassin's Creed 4 is metal. You can loot ship after ship and find very little metal, which is needed in large quantities to upgrade the Jackdaw. The best way to procure metal is to take down military ships, but they can be hard to find until you are a wanted man. As you take down civilian ships, your wanted level will rise and more military vessels will appear. This is a relatively easy way to secure metal.
Now we'll tell you how to find the Templar Armor in AC4.
