Yu Yevon battle gives you Auto Life, if you die on that fight.....well you can't.

Kimarhi is the dopest character in the game hands down. I've sent him thru many paths...the one I found the be my favorite was Lulu's. By the time I was at Kimarhi's 2 on 1 battle, was about the time he started to show some signs of his progression not working.
