One of the first things I will do if I get Sherry aside from awakening her.

Is reform my full army of Irons/Bronzes and then go back to where I left off in story and attempt to continue

My full Iron Army had an fail cascade in Citadel Battle. Pretty sure they will be able to take it with Sherry's help XD

Just realized I was low lvl when I did Citadel Battle and never tried it with prince's Savior buff up..
