Oh god I screwed up hard. First, I messed up my saves and didnt realize I had not obtained Bahamut yet, so that confused me for a few seconds (I went back and picked him up later). Its not a difficult fight, since you have two white magic users and can set up buffs faster, but it takes long because they have a lot of HP and the four of them come in a row. I even messed up and fully healed Rubicante one time xD How many fire bosses absorb Ice!?
