Final Fantasy IV/Tower of Babil - Part 2

Move Hovercraft
On the map find the Tower of Babil. At the bottom left of this island, you will see some shallow water and Eblana Cave. Drop the Hovercraft on land near the cave, and ride it to the entrance.

Cave Eblana
In the first room of the cave head immediately south, as far as possible and you will reach the next door. The next cave is the hideout of Eblana. Continue to the left, and you will see a staircase toward a door. Go through this door. In the next room head north, and the only door will take you onward through the game.

Find Edge
For this room, head to the fork in the path and take the one to the lower right. In the next room follow the path down, to the right, then up again and into the next cave. In this cave, the first door you see is a save point. Continue to the left of that door and you will come upon Edge. He will lose a battle with Rubicant only to join your team.

Re-enter the Tower of Babil
This cave leads to the edge of the Tower of Babil. Edge will jump over the side, letting you in. In the first room of the tower. Follow the horseshoe pattern of the room, and enter the next door you come to. The next room also takes a large horseshoe pattern, so follow this around as well. Enter the first door you come to in the next room.

Through the Tower
In this room go immediately to the right, and it will loop around to another door.

Save Point
Upon entering this room go immediately to the right and you will see 2 doors. The first is a save point. The second will take you further, so enter this door. In the next room, just go through the door, then you will reach final room, where you will find the King and Queen of Eblana.

King and Queen of Eblana
The King and Queen are being controlled by Rubicant. Just fight these guys for a little while, and a cut scene will take over, and they will die. After defeating them Rubicant will appear. He will give you a chance to equip yourself properly (Ice Weapons and Fire Armor). Before attacking he will heal you completely.

Rubicant
Rubicant can be difficult. He will rotate through spells (Fire 2, Fire 3, and Glare) Use ice weapons, Rydia's Ice or Shiva, and Edge's Flood for most effective attacks. However, when he hides behind his cloak Ice attacks will actually heal him, so wait for him to drop the cloak to attack.

Crystal Room
After defeating him a messenger from Eblana will come in and speak with you. After leaving head toward the door that Rubicant blocked, and you will be in the Crystal Room. When you try to take the crystal, you will fall into a trap. Continue along the path of the tower through 2 levels.

The Underground
When you reach a room with a fork in it, take the path on the left. Through that door you will find an airship. After the cutscene, use it to reach the Gnome City. Speak with the King and he will tell you that the final crystal is in the sealed cave. Luca will give you the key.

Cid
Go to the basement of the castle, and you will find Cid through the door. He will fix your airship so that it can fly over the lava. Now you can reach the Sealed Cave.

Optional Sidequest
This would be a good point to attempt the Cave of Summoned Monsters. In order to do this, Rosa must have learned the Wall spell. Cave of Summoned Monsters << Tower of Babil | Sealed Cave>>
