I've found an easy way to beat Emerald. Just get mime linked with counter on everyone and one with w-summon, knights of the round with hp absord and hades or chocomog with mp absorb hp and another with final attack and phoeix. Now get everyones Hp above 8000 and use demis to get there hp to end in something near 77 then use the catsbell or mini to make there hp end in exalty 77 then use hi-potions and potions to make them all 7777. Then fight it and you people will attack him about 15 times each for 7777 then go back to normal. Now use w-summon knights of the round chocomog and mine until it dies. ENJOY. Please tell me if this works for you.
