Chainmail Armor

Chainmail armor has been in the game for a long time, with no crafting recipe that stuck around to current Minecraft. However, we have chains in the game now and it would make a lot of sense for Chainmail to be craftable using these.

I also think that a new variant of chain should be added, since the release of the Tricky Trials update. The copper chain, crafted with 2 Copper Nuggets and 1 Copper Ingot. Copper nuggets would just make sense considering both Iron and Gold have nuggets, and it would fit the theme of the Trial Chambers. It would also allow for Copper Chainmail armor being crafted, with 80% the durability of normal chainmail armor, while also weathering over time, and increasing the chance of the player being struck by lightning. The weathering acts as another way to lower the durability of the armor, with the higher oxidization making the armor more fragile. Of course, this would be fixed with wax or being struck by lightning.
