Instructions
Fight random battles until Sabin reaches level 10. Sabin learns the suplex blitz technique when he reaches this level. You cannot do the move before Sabin reaches level 10.
Get into a battle and choose "Blitz" from Sabin's available commands. Proceed only when the input cursor (a gloved hand pointing at Sabin) appears.
Press the "X," "Y," down and up (on the control pad) one after the other in that order. Then press "A" to finish the sequence. If done correctly, Sabin's next move will be the suplex attack.
