Things You'll Need
Instructions
Complete the first half of the game until the party finishes the "floating continent" area and reaches the world of ruin. The eight legendary dragons must all be defeated before the Crusader Esper can be found, and they are only located in the world of ruin.
Travel to the city called Zozo and buy the "rust rid" item from the merchant hanging out near the town's inn. Head to the town's cafe and go to the top floor. With the "rust rid" in tow you can open the door at the top of the cafe and gain access to Mt. Zozo. Travel through Mt. Zozo until the party reaches and area with a switch near a chest. Press the switch to open the chest and unleash the first legendary dragon. Defeat the dragon in combat.
Take a trip over to Figaro Castle and ask the engineer to submerge the castle and travel underground. When the castle runs into something unexpected, stop the castle and explore the cave you've run into until you reach the ancient castle. Travel through the castle until you reach the area with the statue of Odin. Move five spaces down from the throne on the right hand side of the room and press the action button (the "A" button in the SNES version) to reveal a hidden room. Go into the room and then down the stairs to fight the second legendary dragon. This dragon is weak against fire attacks but resists ice and water attacks.
Go to the Opera House and enter the second floor seating area. Speak with the owner of the Opera House and then go to the room at the top right of the screen. There will be several switches on the wall in this room, press the third one to be dropped to the stage below and battle the third legendary dragon. This dragon is aligned to the earth element, so wear armor that absorbs earth attacks to make the battle especially easy.
Fly the airship to the star shaped mountains above Kefka's tower and set down in the small strip of land in the center. You will be forced to split your party up into two groups and use both of them cooperatively to press switches to advance throughout the area. Make your way through this place until you find a spot where you can bypass a staircase and instead head down to a treasure chest. The fourth legendary dragon will be waiting in front of the chest, and this one will use fire based attacks against your party.
Head off to the town called Narshe and go to the place where your party defended the town from the Empire's army at the beginning of the game. Just before you reach the bridge, you will be attacked by the fifth legendary dragon.
Journey to the fanatic's tower where the cult of Kefka has taken up residence. Go through the tower until you reach the third room containing a treasure chest. Inside the chest will be the sixth legendary dragon. Keep in mind that your party can only cast spells while in the tower instead of being able to use their normal attacks, so make sure you have enough powerful combat spells readied to defeat the dragon.
Proceed on towards Kefka's Tower, the final area of the game. As you make your way through the tower you will forced to fight the final two legendary dragons. The party will receive the Crusader Esper after the battle with the eighth legendary dragon.
