Mad Ogres:
To win this battle, you will need 50% power and 50% luck. The strategy remains similar to previous bosses, have Kain jump, Rosa heals, Rydia summons, and Cecil attacks. However, Rydia�s summons only deal 1 damage each, so attack with her. Have Edge throw a couple of shurikens and attack, and Berserk Cecil so he does more damage. If you win, you get an Ogre Axe.
Continue along the path and enter the door. Ignore the first door you see and get the Succubus from the chest. Go back and in the door. Take the right path and get an Ashura blade. Continue left and enter the door. Follow the path right and ignore the blue orb. Enter the first door and save your game. Go through the second door, and take the left path down. Go over to the left side to get 82000 Gil! Return to the middle of the room and go up. You will see Edge�s parents, and you will engage in a battle.
K.Eblan, Q.Eblan:
Use the same tactic as the Mad Ogres, but this time summon with Rydia and attack with Edge. Titan works well here. After a while, they will regain consciousness. They will die.
After the battle, Rubicant appears. Don�t worry if you have minute health left as Rubicant will heal you. Edge will learn Flood and Blitz, and you will engage in battle.
Rubicant:
If he uses Scorch, he will probably do a lot of damage. So keep healed, and only attack when his cloak is down. A well placed Jump attack can do over 4000! Keep up the same tactics and keep your party healed.
OK, truth be told, I had a lot of trouble here, so the tactic I used was Kain Jump, Edge use Flood or attack, Rosa Heal, Cecil Heal and Rydia summon only when he has his cloak up.
After the battle, some Eblan guards will come and talk to you. When done, head through the door. When you enter, you see all of the crystals. But�it�s a trap! After the fall, head up to get a HiPotion, then go south through the door. Continue along the path, go through the door and keep going. Go right at the split to get another HiPotion. Return to the bottom and go left. You will end up in a room with an airship that Edge names the �Falcon�. You are once again, underground, so save and return to Dwarven Castle.
