Just get his chain gauge up like on the other bosses by either Rav/Rav/Rav, Rav/Sab/Rav,
or Rav/Rav/Com. The commando is needed to keep the gauge still so that it wont go down
quickly. Next, if you get him to critical (get full chain) switch to the best damaging
modes your team has. If you are about to die use medics, depending on how much dmg youve
taken the more medics you use, but if you don't have time to change then bring out the
summon which will heal your party to full and do some damage. Thank you very much and I
hope your the one who kicks his butt this time.
