Hey!! I'm new but i DO know enough about FFVII to answer this question ^_~

Alright, that combo stated above would work really well.... but i'm going to give some instructions in case some ppl dont have master materia or mime and such....

Here we go... =D


Alright... at the beginning of the battle Ruby will whirlpool 2 of your team mates away and you will have to fight him one on one with a random person from your 3 people... BUT, you can get passed this by killing off two of your characters, and leaving one alive...

By doing this, Ruby will stick his tenticles in the ground right away... after he does that you can revive your other two team mates and make the battle much MUCH easier...

Okay... After he puts in his tentacles u can then attack... if you're on a high enough level you dont really need to do much except for Attack, Heal and Revive (if someone dies)... But if you want to speed stuff up, you can Summon Death and parylze him... combo'd quadra magic will work good too, reflect on your characters and quadra on your characters will be REALLY good...


So yeah, if you follow these instuctions and dont get careless Ruby will be a snap... Too easy... =P
