I have purchased all the weathered gear/accessories I need, and the interim weapon with Rowena's tokens, and have to wait until I rank up in Flames before I can continue my 3rd relic book. Problem is, I have nothing I can see to spend my soldiery tomes on.

Any suggestions? Maybe something I can purchase now that I will need for later quests? I can't get Sacred Spring Water yet, I'm not that far along in the zodiac quest line.
