91. Now head back to the entrance. Go down the first path (Between the two sets of stairs). Both the computers have monsters in it, the right one is a matrix error. Use an air bomb on the door to the left to get 12x laser, 10x bazooka, 11x Hi-jacking, 11x wave vibrator, 10x semi conductors, and an H-bomb. (If you have the luck ring equipped you will get a few extra lasers, bazookas, and wave vibrators) Flick the switch to on and be attacked by a matrix error. Now walk straight up. You will see the brain. Choose your party and heal up then save. Now talk to the brain. You have to fight the brains minions first before you have to deal with him. First lot are evil blood drops. Then he will summon plasma blood. These things heal themselves and revive. I find that Herbert’s Aura bomb works really well. Also Yveen’s Armageddon, Sarahs Sun boomer, Wendala’s carnage and Random’s Fury spells works well. You will now have to face 3 evil pseudopodes. Same technique again. It will now cut to the item screen to allow you to heal up again. Also equip the cerulean rings if you have not already done so. Now use Random’s fury spell on it, use sarahs sun boomer attack, Wendala’s carnage and Herbert’s aura bomb. Yveen will be glued for a while. When unglued use her Armageddon attack. It does regenerate 3000 HP as well. (You can inflict it with venom to counter this regen effect though) Once it’s dead quest complete. Yveen thanks you for saving her and takes Sarah back to complete her trial. Talk to the angel in front of you. She will tell Sarah that she has an angelic touch inside of her which allows her to heal her friends. The angel gives you an angel gown and Sarah gains 55MP. Sarah has become a half angel.
