This battle took me forever. I assume you are playing as lightning. I used Hope and Vanille. I had to fight all the monsters behind the entrance to get money, and upgrades for weapons, (sell incentive/credit chips) I probably did that for an hour and a half.
the actual fight:
Rav (Light)
Syn (hope)
Sab (vanille)
I used a librescope to see all the heads weaknesses.
tried killing heads whilst hope was powering me up.
once hope was done, set to
Rav
Rav
Rav/Sab (and Med when needed)
once the heads were gone:
start fighting. using mostly tri-diaster (rav/rav/rav)
and adding a med or three when necessary.
when staggered:
swich to
Com
Rav
Rav/Med
his super attack is a pain in the butt:
so almost always (I think 100% of the time (not enough proof though)) if you get hit with all three you will die. So there are a few ways to counter act this.
One:
attack him with
Rav
Rav
Rav
He will grunt and not release his full attack
Two:
Summon Odin
When he is releasing the attack,
or go into gesalt mode when he is releasing the attack.
Further notes:
use hope as a Syn whenever you need to.
Heal, never let your health get to red.
If one or both of your party members has died, summoning Odin will revive them.
thx ill give it a shoot
