Junkomancer
You're a wiz at forging armor from junk. During your daily preparations, you can review the formula of one armor upgrade in your formula book of your level or lower. Until your next daily preparations, whenever you cast junk armor, you can Install this Upgrade even if there are no available upgrade slots. If you're a master in Crafting, you gain the armor specialization effect of any junk armor you wear.
