OH MY GOD that fucking Ultima Weapon fight

Me, a Sage, a Gunbreaker tank, and two Red Mages who had no idea what they were doing

first run, we died to the Ultima cast because they didn't LB in time

second run, I died trying to keep their asses alive

third try, we finally knocked it to 0.0% just as the Ultima cast was finishing

how do you get far enough to grab Red Mage without knowing how to dodge attacks
