Need Help Defeating Gilgamesh >.>;

[Thief of Hearts Joker]

Well first off I finally found a way to chip down his annoying health but alas when he gets to 40% or so he goes all berserk and owns my team with only a few attacks....

My team has decent defenses but even with Sentinel + Medic + Syn he takes me out before I can buff and heal the damage he nailed me with...

Mostly use her to chain gilgamesh don't really use her in stagger.


As for my strategy.

Part I
I use Rav/Rav/Rav to chain Gilgamesh into Stagger, if he does damage to me I switch to Sen/Med/Syn for heal and atk buffs or Sen/Syn/Syn for defending buffs, Just before hes staggered I go into Sab/Sen/Rav to do De Protect/DeShell/Imperil the second he goes into Stagger.

Part II
Once Staggered switch to Yakshini's paradigm and use his Feral Link for a quickie buff, I then go into Com/Com/Com with Lightning Requiem and deal out around... 1 Mil in damage I believe more if one of us nails with last second punish move for a extra 70-200k

He heals a good chunk of my damage dealt to him but I managed to get him knocked down to 40%

but everytime I get that far he goes berserk and unleashes Divider/Multi Hit Combos which decimate me even with a Sentinel :/

Anyone know how I could defend against his assault?
