Master eight Counter (Support) and eight Mime materia. Equip these on a character who has a limit break that hits many times (Omnislash, Highwind, Anger Max, Doom of the Living). Equip another character with the W-Item materia. Kill off the third character to increase the chances of Emerald hitting the counter character. Get the counter character to full limit break. When in battle, have the W-Item character give the counter character two Hero Potions. Then have the counter character use his or her limit break. When Emerald hits him, he will counter-attack eight times with that limit break. If your levels are high enough, this will be more than enough to kill Emerald.Originally Posted by aeris2001x2
