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...
my stats are and team is...
Weapon: Gandiva ((best I have atm till Long Gui drops some Adamantite -.-; ))
Accessory: 2x Durable Shamans Mark (( 40% Increase in Magic))
Accessory: 2x Durable Brawler Wristband ((Atk + 40%))
Lightning- Requiem DLC
Atk ATB Charge II
Resist Physical Damage 26%
Feral Speed II
She does 8000-10000 normal hits and does 38000 when staggering him with Bravery and Deprotect.
Resist Physical +15%
Resist Magic +15%
Mostly use its Bravery/Faith Buffs along with its Feral Link for a Quick mega Buff when Gilga is staggered
Attack ATB Charge II
Resist Physical +26%
Feral Speed II
Siphon Boost II
Mostly use her to chain gilgamesh don't really use her in stagger.
As for my strategy.
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.
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?
