The Limit Break Manuals

To get the Level 4 limit break, you need to find a manual somewhere in the game. To use it, the character that is going to use it must have all their level 3 limit breaks.

- Cloud: Go to the Battle Square in the Gold Saucer and earn at least 32,000 BP, then buy the Omnislash manual.
- Aeris: Go to the cave surrounded by the river. You can get there early in the game by using the buggy. The Shinra Cargo ship will transport you across the sea, so drive the buggy into Costa del Sol to enter the Cargo ship with the buggy. When you get out of Junon, you will be in the buggy. Talk to the man in the cave and he will tell you how many times you fought or escaped. Make the last 2 digits of the number of the times you fought the same, then go back and talk to him, he'll wake up and give you a Mythril. Go to the weapon store below the Gold Saucer, and talk to the weapon crafter. Choose to open the small box, and you will get the Great Gospel manual.
- Tifa: Go to her house and play the Highwind theme on the piano. Make sure Tifa is in your party. The tune goes: X, Square, Triangle, L1+Triangle, L1+Square, X, Square, Triangle, L1+X, O, X, Square, X.
- Barret: Stop the train at Corel on the second disc and talk to one of the women in the tents, and she'll give you the Catastrophe manual.
- Red XIII: Open the locked safe in the Shinra Mansion and defeat Loss Number. The lock combination is right 36, left 10, right 59, and right 97.
- Cid: Go to the cargo bay in the sunken Gelnika plane.
- Yuffie: Defeat Godo at the last floor of the Pagoda.
- Vincent: Go to Lucrecia's Cave on the second disc. You can ride the sub to a tunnel-like passage to get there, (North penninsula where Costa del Sol is) or ride a blue or green chocobo. Go there again on the third disc to retrieve the manual.
