Armor Enhancement

When crafting armor in, you can change the Refined Elements you use to produce a different modifier. An example is a Plate chestpiece you craft with Copper Sheets, Supple Leather Straps and White Iron Bindings would have the Copper, Supple Leather and White Iron Bonus. This modifier does not stack so using the same metal (Copper + Copper) twice won't double the bonus.
