I got Zidane at 100 and I am playing Sephi now.
I like Sephis BRV-Attack because they are long ranged and fast, but I hate his HP-Attacks, just like Lestat said his HPs are too easy to evade.
Fights I use normally a Minute to finish are 5+ min fights because i can't do HP-Dmg to my enemies.
Lestat, have you any tipps on using Sephi?
