Seymour on gagazet
Beating Seymour on Mt. Gagazet: First have kimahri's overdrive gauge up before getting into battle, once fighting use kimahri's overdrive mighty guard (which you can get from biran). Now he should not be able to kill you with total annialation or cross cleave but make sure you use mighty guard on yuna, kimahri and tidus because yuna can heal and the other 2 can use talk to get their strength up. Get yuna's overdrive up and summon bahumut. Use bahumut's overdrive mega flare. This should take about 10-12k off. Then just keep attacking with tidus and kimahri. (Make sure you kill his other part twice or he will use dispel)
