Gorkii


To make this battle much easier you should equip Yuffie's armor with an Elemental-Gravity combination to protect her from Gorkii's Demi 2 attack. Also give her a Cure, Barrier, and Coutnerattack materia as well. As soon as the battle starts you sohuld cast haste on Yuffie and also remember to keep her health up throughout the battle.

Gorkii's demi attacks should have little effect with the Elemental combo equipped so it is just a matter of staying alive and out lasting him. You get an X Potion for winning.
