To get this straight I'll tell you how you get the Limits for Cloud. And I mean EVERY Limit.

Limits level 1
Braver: You have it the start
Cross-Slash: You have to use Braver eight times

Limits level 2
Blade Beam: You have to kill 120 enemies with Cloud (you can use magic too)
Climhazzard: You have to use Blade Beam seven times

Limits level 3
Meteorain: Kill 200 enemies (after those 120 you need for Blede Beam)
Finishing touch: You ave to use Meteorain six times.

Limit level 4
Omnislash: You have to get 32000 points and exchange them for Omnislash-item (you can get the points with anyone, so it doesn't have to be Cloud)

So theres the "little Guide" for Clouds Limits. Että olkaapa herrat ja rouvat/neidit vaan tyytyväisiä tuohon.
