No magic no summons no help, just a straight up 1on 1 sword fight
How is Lost Odyssey? I haven't played that game.
It's not bad but calling it good gives it a bit too much credit. It's better than FXIII though.
Kaim is unable to be killed unless it's by another immortal of his world, if I remember correctly. So yeah, he wins if it's to the death since Lightning can't kill him. But for a KO victory, I still give Kaim the decisive victory. The dude is very tough from withstanding fatal wounds. He'd be tough to put down.
