Mooncloth, bags for you and bank alts, blue/green gear that is better than what you have (if when not fully BiS-ed out yet). Do note that if you are investing in revered in Thorium then in ~P3 there will be nice pants recipe there.
But this pant is BoE so anyone who are “Revered” in Thorium can make it for you.
Also, there’s Bloodvine set when ZG is available, So if you plan to drop Tailoring, you will have to re-up Tailoring after ZG is release i think it’s bis for mage. You can wear Bloodvine set without Tailoring, but you don’t have the bonus .
