Amazon is giving us new screenshots of the craftable armor in NewWorld. Sets will be seperated into different categories. There is the plate armor, you will need to farm ores for. If you decide to hunt animals instead , you will be able to craft leather clothes. There are more types of clothing. New World lets you decide what type of armor you want to wear.
At the moment we cant say what benefits a certain armor will have. But we guess that plate armor will slow your movement down , but increase your defense. In comparison to that , the leather set wont protect you from attackers that much , instead you will be more evasive.
