Right as lestat said seraph crowns help

BUT I just used Vanille, light & Hope

Vanille cast poison which made everything easier

having all 3 on ravager build up stagger meter

having all 3 on medic really helps health

And by luck I beat him quickly...before he could use death on me.

I used to have Light, Fang, and Vanille but then i took vanille out and put hope in.  I think ill have to take fang out of the party for this battle and put vanille back in.  After i grind a lil bit ill battle him again and hopefully i can beat him.  Ill try your paradigns just in case.  Thanks!
