Congratulations! How did you best sapher?
Truth to be told, I didn't really do any of magic nor summons.
He never killed Barret, who had his heavy Missing Score loaded with high materia and every time I shot him it was 30K or nearby, had him on offense with a mastered Double Cut materia.
Used a few Hero Drinks on him, and had the rest of the party heal whenever he did high damage, I did use Vaccine on everyone before starting to attack.
What I don't get it how this time my physical attack on him never did 1 HP of damage like it did last time, maybe it was that crazy attack that left my party on 1 HP but on this battle he didn't use it, maybe I was lucky.
Seriously I didn't use anything besides Barret's Missing Score, I did the same thing for Bizarro but he too longer than safer
