The Armor Imbuement table uses the Infused XP of any Armor to add new Armor Imbuements to it.
Never use Dispel on any leg armor. It is a known bug. There is a bug in the code that can corrupt your world. If you put Dispel on any leg armor your game instantly crashes and you will be unable to load it again. There is no known way to repair worlds that were destroyed this way.
