Things You'll Need
Instructions
Play through the game until your party reaches the area called Mystic Village. Head outside the village and travel west to the nearby mountain range.
Head inside the cave at the south end of the mountains. Fight the monsters inside the cave repeatedly until the characters named Lucca and Marle learn the spell called "Antipode."
Go to the very back of the cave system and approach the large blue monster called Heckran to initiate combat.
Have Lucca and Marle cast the Antipode spell on Heckran and then have the character named Chrono use his lightning bolt spell. Wait for Heckran to attack and then have Chrono use curative items to heal the party members that get hit.
Hold off on attacking when Heckran leans over and holds his claws out, as that indicates that he will unleash a devastating counter-attack. Use healing items during this time or simply just wait until Heckran moves back to his original position to resume attacking. Continue casting spells on Heckran until you have dealt 2,100 points of damage to defeat him.
