Get they Myth(Hero's Ring if you don't have already). Run Ulitmas ballad, that is crazy easy for tanks, and the ring is ok for i80. Also, if you feel you won't get the UAT anytime soon, then spend the Soldiery. I saved up the 910 or whatever was needed, then considered that as 0, then spent when needed above that.

You do have a few good free options out there though if you wanna keep dat currency.
