Eidolon Help

If I've been playing this game correctly, I can safely assume these are the toughest aspects to the game, since they have a vague and barely hinted at strategy to defeat them. So far, I've only conquered the Shiva Sisters, Odin and Brynhildr. Each of them required a couple tries because I devoted the entire first couple battles into figuring out what the hell to do. I grind every oppurtunity I get and these prove to still be more difficult than standard bosses every single time.

I wanted to make this thread since they are the toughest enemies in the game (so far), and for those who have conquered them to give your strategy to conquering them.

For me, I conquered the Shiva Sisters by basically guessing what to do, I used Provoke once and used Steelguard for the remainder of the battle. I got through in two tries because all I did in the first battle was figuring out how to use Libra. >_>

For Odin, I really had to think, and I reread the manual to remember what a Chain Bonus was. My Paradigms included Dualcasting, Yin and Yang and Symbiosis. Keeping Symbiosis as my primary Paradigm for the start of the battle to keep Odin from dealing significant damage. My basic theory was staying in Dualcasting when he would sit still for a moment and switch to Yin and Yang for emergency healing, I got through in five tries because he dealt way too much damage too fast the first three tries and the fourth try, I just screwed up really, really bad. Spark Ring* was equipped to both Hope and Lightning the fifth try and it helped a lot.

Brynhildr was probably the hardest for me, I managed to get through in three tries, but most of the time, I had Vanille on Medic while I spammed Ravager spells on Odin. But, like a few the enemies before the battle, I would squeeze out Vigilance and Haste before doing anything, which helped significantly. My Paradigms included, Yin and Yang, Dualcasting, Dualcasting, and Tide Turner. Two Dualcastings made it so I could cut the time to cast spells on Brynhildr, increasing the Gestalt Gauge much faster, although it would leave me open for attack every time I switched. Brynhildr was supposed to be the easiest Eidolon thus far, but I highly believe Odin and the Shiva Sisters were less frustrating and slower paced.

Any warnings on future Eidolons would be greatly appreciated.

from what it sounds like, you are using a lot of ravagers, throw in at least one commando once in a while, since it will slower the gauge from losing all of your progress. Also a sentinel is good to have for tough battles. Hope, Lightning, and Fang is your best bet for most battles. I hardly ever used Yin Yang. Try Relentless Assault, Solidarity, Delta Attack, .....combat clinic, hmm I trying to think what else I used

Relentless Assault wasn't available to me for these fights, but I will keep that in mind.

I also heard the females are the best characters in the game, and I'll work to figuring out why, since Sazh and Hope are proving to be my most used characters.

i shall list the Eidolons and (what should be) the best methods to getting them.... unfortunatly i can't remember the order they appear in... so it shall be alpabetical order lol....

Alexander
~Yields to those who amass chain bonuses~
~Yields to those who heal the wounded~
~Yields to those who strengthen their allies~
~The moment the battle begins switch to the paradigm 'Delta attack' and go straight into attacking~
~When a party members health drops below 50% paradigm to 'Combat Clinic' and have the 2 medics heal everyone, one done switch straight back to 'Delta attack'~
~Alexander should yield when the doom counter reaches around the 300 mark~

Bahamut
~Yields to those who amass chain bonuses~
~Yields to those who defend against and endure attacks~
~Yields to those who weaken and debiitate their enemies~
~Switch to 'Combat Clinic' when the battle starts and use 'Auto-cover'~
~When the doom counter reaches somewhere between 1,000 and 700 switch to 'Delta Attack'~
~You can also use 'Metador' which also helps to increase the gestalt gauge, but 'Delta Attack' is most likely better~
~Bahamut should fall when the doom counter reaches around the 300 mark~

Brynhilder
~Yields to those who amass chain bonuses~
~Yields to those who strengthen their allies~
~At start of battle switch to 'Tide Turner' and manually apply 'Vigilance' and 'Haste' to both party members in that order~
~Switch to 'War & Peace' to heal, then alternate between 'Dual Casting' and 'War & Peace' to drive up the gestalt gauge~
~Brynhilder should yield around around 2 minutes into the battle~

Hecatoncheir (may take 2 or more tries)
~Yields to those who amass chain bonuses~
~Yields to those who heal the wounded~
~Yields to those who weaken and debilitate their enemies~
~Use 'Slash & Burn' untill Fang runs towards the Eidolon to preform her second set of attacks~
~Immediatly switch to 'Stumbling Block' and use that, occasionaly switching to 'Lifeguard' when needed for the rest of the battle~

~If your first attempt at the battle fails, then create the Paradigm 'Arcane Defense' (Ravenger + Sentinal) (if you want to know how... when you select 'Retry' keep pressing Triangle and you can enter the menu)~
~Start the Battle as before but use 'Stumbling Block' with occasional bursts of 'Arcane Defence' using 'Lifeguard' when needed~

Odin
~Yields to those who amass chain bonuses~
~Yields to those who heal the wounded~
~Consider changing the battle spped in the options to slow to buy yourself some time~
~Symbiosis should just get you through the opening onslaught~
~Wait for Hope to case Protect and Shell on both party members~
~Switch 'War & Peace' untill he preforms his 'Ullr's Shield' ability then immediatly switch to 'Dualcasting'~
~If you need to heal use 'War & Peace' the switch back to Dualcasting~

Shiva (Stiria & Nix)
~Yields to those who amass chain bonuses~
~Yields to those who defend and endure against attacks~
~After beating the PSICOM solidiers switch to 'Sentinal' that should be enough to win the battle~
