Prior to the battle, equip one or two Seraph Crown * to your party leader. Other than his instant death attack, he's actually a push-over. Make sure you use Combat Clinic (SEN/MED/MED) to heal whenever he does his ultimate attack

Where do i get the seraph crowns?  And yea I have Discretion i think it is.  Whenever he does his ultimate attack i just switch to discretion and heal myself.  I dont have a problem with his ultimate.  Its that fucking instant death attack.  He had 50,000 left and he fucking killed me with that shit.  There is another fight after that right?

You can't buy a Seraph crown, you'll have to make one from Cherub Crown (which are bought from B&W Outfiters). It takes 6 level ups and a Perovskite to upgrade it from * to Seraph Crown. It's worth it though, a Seraph crown * has over 60% Death resist. 

There's another fight yes, but it's easier than the first stage. 

Ok but there is one little problem.  I wasted all my gil in equipment that raises my life by 300 or 400 i forgot.  Still thank you for your advice.  
Do you recommend grinding?  I put a synergist in my party(hope) for this battle thinking he was going to help(which he did), but he doesnt have haste.  He just has protect, shell, and vigilance.  I need about 100,000-250,000 CP to get haste which will be a huge advantage.
