Making this for sale on the Drinal server.
With the last patch indicating drop rates on temper ingredients will increase, I could imagine making and selling these for 3k - or even less depending on how much of a change there has been to the drops rates.
At the moment I would charge 6k, which no-one in their right mind would pay, so they will not get made for sale (price is based on the fact that I could make an imbued breastplate with the temper and sell it for 6k, so why would I waste the temper on something that sells for a lot less?)
