How do you beat via infinito

[stesia]

chac is easyer to fight if its in oversoul as it wont use heavens cateract
on you.but you cant guard against its petrify if your party is fast enough you could use the catnip and gunners trigger happy to beat it if you have auto life on a garment grid it helps as well.

the paragon can be fought in a similar way or you can bribe it for about 1 000 000 gil and challenge it later which is easyer because you fight trema straight after and have no chance to heal before the fight.

you need a high defence ,break damage limit and if you have it the mascot dressphere with all its abilities use, if not dark knights should work
immediately use a soulspring on trema to drain all his mp and if you need to cast protect and haste then use special attacks on him as normal ones miss
