MIME: Materia cave south of Wutai (Green, Black, or Gold Chocbo- required)
Knights of the Round: Materia cave in North-East Ocean (Gold Chocobo- required)
HP Absorb: After the Wutai scenario, go to the Cat house and up the stairs. Down the hall there is a chest with th HP Absorb materia in it.
Hades: After aquiring the submarine, go to the crashed Gelnika. In the cargo bay, this summon is located under the broken submarine.
Quadra Magic: Materia cave near Mideel (Blue, Black or Gold Chocobo- required)
W-Summon: Battle arena in Gold Saucer. Cost: 64,000BP (Battle Points)
First go into a regular fight, NOT the Ruby fight, and kill the two party members that you don't want to fight the WEAPON, to prevent it from using its quicksand attack. (which eliminates one living party member from the battle, and could result in a game over if Cloud is eliminated) Then save your game, and either fly the Highwind or run a Chocobo into the head of the monster. As you killed all of your party except for Cloud, it will dig its claws into the sand. If you didn't it will cast quicksand twice, eliminating two party members from the fight. When its claws are in the sand, W-Summon Knights of the Round and then Hades. KOR will take a good amount of health away from RUBY, and Hades will be cast four times, eventually paralyzing RUBY itself, and then its claws. Don't worry if RUBY casts Ultima before you can cast Hades, because once you do, it will be paralyzed, and it usually misses anyway. Mime KOR again, which if you attached it to HP Absorb, will Absorb around 9000 HP back into you. NEVER interrupt your chain of spells to cure yourself...you may not be able to start the chain again.
ORDER OF ACTIONS:
1. W-Summon KOR and Hades
2. Mime that W-Summon
3. Continue that chain until RUBY WEAPON dies
