Enchantment Overhaul

Burnishing (axe): right-click weathering copper to strip all oxidation in one click; the axe loses durability equal to the stages skipped. Wraith (armor): the enchanted piece is hidden while the wearer has Invisibility, per equipped piece. Enchantments already on an item can now be upgraded one level at a time from the catalogue, paying only the delta in reagent, XP and slots. Burnishing and Wraith generate as enchanted books in matching structure loot.
