Nightvision Goggles can receive enchantment, but make Nano Helmet with enchanted Goggles is finished without any enchant.
Nano Helmet (also other "Nano") cannot be enchanted with anvil.
In other series of mods: if armor piece have enchant, result of upgrade have same enchantments .
Tools, also cannot be enchanted. "Soft touch" for Drills is very demanded.
With Actually Addition, I can create Augment "rune" and insert into Drill. For speed, luck, soft touch, as example.
May use this method - create a small parts, enchant it and insert into Armor and Tools ?
