On fighting Vargas, i have to use to use Sabin's Blitz Skill. I just found out how to do it. But in the game, how do I find out how to do Blitz? It has that down thing on Sabin, and I thought I had to push the down button, then press the X button. How do I know how to do the Blitz thing? [I mean in the game, not using help on the Internet.]. I duing to beat Vargas. HELLP!
