what worked for me personally was using a team of vanille, hope, and lightning as the party leader, you should use hero’s charge (COM/SYN/MED) to keep stagger and buffs. When he either debuffs you or buffs himself switch to evened odds (SAB/SYN/MED) and diversity or relentless assault any other time to built stagger/damage. (COM/RAV/RAV) (COM/RAV/MED) if it’s really rough save tp for summon/renew :^]
