[Chocobo Dyl]

I did sephy on lv.56 on hard so...

First make sure she has all combo plus on then the combo finishers and aerial finishers add double jump and glide,throw in Guard,the HP thing were if your left with 1HP after a combo you still live and that's just abilities.Custimize so you have magnet,cureHi-potion(not on auto reload and equip 5)and 1 ether or elixer on your shortcuts.Preparation,Done.

Now for the fight.
When he uses his quick slash use block reaction and attack until he turns around or dissapears.When he turns around use guard TWICE and attack again.if he slashes you up into the air then let him,once your in the air attack like mad until he dissapears.when the dark orbs come around you,use magnet.when he uses his "Heartless angel"attack lock on,double jump and attack him like mad.When he uses his fire attack jump away.
When he uses meteor attack lock on and fly around.Rinse and Repeat until done.
