If you really want to kill this guy, first equip Cloud’s Apocalypse sword (triple AP gain!!) and just attack with KotR(as described above) – you’ll get 150,000 AP for all materias equipped on the Apocalypse sword. As you can see, you don’t really need a weapon to defeat Ruby. He’s easy as pie. Just stick to the above tactic and you’ll kick his ass.
If you’re lucky, but I like KotR+MP absorb, W-summon, Mime, Final attack+Revive.
1. w-summon ZERO
2. Ruby will put his tenticles into the ground.
3. w-summon KOTR and mime until he is dead.
I didn’t even use hades or final attack.
why?
1. Hades doesn’t do much damage, and Ruby’s counter attack, ultima, really didn’t do that much damage. I used pheonix downs to revive characters and then used a megalixer. I don’t like final attack for this battle because if you are stuck in a mime sequence and someone uses their final attack, then the character will mime whatever that final attack was and it will waste an action.
he dies in about 7 hits with KOTR (plus the 2 from ZERO).
