well...my whole team is like level 78-80 and i can't beat Brach...i use Kain, Rydia, Cecil, Rosa, and Cid(he has higher DEF,ATK,and HP than Edge)
i do a lot of damage to him, and rosa casts holy half the time because he doesn't do much damage to my team, then he cast reflect on himself and bounces spells off very quickly and kills my whole team!!
help =(?
