Does anyone know how to open those red chests in the Battle Tower? You have one on each platform of the tower where your trainer, alchemist, necromancer, and forger are. Then one in your tower on the lower level where your illusionist is. I can't seem to open them. I have no keys for them. I've searched the entire tower for the keys. I've beaten all the quests side and main with the exception of the very last battle against the Divine and what not. Help?
