I think I've did most of these over the years already. The ones I'm sure I haven't done are 30 back attacks considering I almost never use What's That!?, Excalibur II because rushing this game isn't fun and have a character with all status ailments and buffs at one time. I'm not sure if that's possible considering how quick some of these fade off like Protect and Reflect. I don't think I've used defend 50 times either. That ability seemed to stop being that necessary since Final Fantasy VI.
