more advanced armor system

since both chain and leather already exist in game It would be pretty cool to add some functions such as, an under layer, there could be spaces in the inventory that allows the player to put either chain mail or leather underneath there standard armor much like in real life except the player has to choose one or another, both could add there own special armor buff, like chain mail adding protection against bladed weapons like the sword, spear, axe, arrows from a certain distance, etc, whereas leather could add resistance against heavy weapons like the mace, axes (since the ones in game are technically wood cutting axes and would be heavy), and explosions from a certain range, you could still enchant the under layers with unbreaking, mending, etc so that they don't break as fast or just add more base durability to both chain and leather sets.
