Geez. So I went to beat Zeromus thinking I'd be fine (I'm at level 70 for all my characters) and he totally kicked me ass after I threw the crystal!! So I have rosa on standby cure and I have kain jump and cecil attack with rydia on standby items and edge throwing and attacking. The problem is that he uses big bang like twice in a row and mostly all my party members die after the first hit. WTF? I can' surivive that, even with shell and defend. Even if I revive rosa for curaja its still pointless because he'll do it again a second later. what should I do??
