Final Fantasy 7 Hints

First you will need 1 Master Comet materia, 1 Master Quadra Magic materia and 1 Hi-Potion. Before you fight with Ruby, kill the 2 members of your party then equip Comet linked w/ Quadra Magic in the weapon/armor of the remaining member and make your HP go to 7677. After you've done the following fight Ruby weapon. At the start of the game Ruby will stick it's claws to the ground, use the Hi-Potion and you will have the All Lucky Sevens and will attack Ruby 62 times w/ 7777 damage, after the 62 strikes Ruby will retract it's claws, use Comet 2 w/ Quadra Magic on Ruby then it will stick its claws again after that use Comet 2 w/ Quadra Magic on it's claws and it will retract it again, continue attacking it and it's claws alternately until you defeat ruby. Note: If done correctly you can even beat him without taking any single damage.

If your having trouble getting the Alexander summon material here's the way how to get him. After the snowboard sequence in disc 2 go to the hot springs and click the option "touch it". After a while you'll faint and be in a shack leave the shack and head down the hill. At this point you'll have to leave markers by pressing the circle button. Head north and leave the markers in a straight line because the wind will blow and you could get confused on where your heading. There will be a small cave ahead, inside there’s a pot with an "All" materia inside. Leave the cave and keep heading north until cloud just pauses and you will reach an area with a small cave ahead. Go inside and talk to person that's there after she will fight you, she only uses cold breath and ice2.Be sure to have a good amount of potions, or hi-potions. After the battle she will disappear and Alexander summon material will fall out of the sky. {you can also obtain Alexander summon material in disc 3}
