Gah i cant figure out how to chain the combos like omnislash 5 halp
Have you learned Omnislash 5 yet? If you already have it learned, you just go to the abilities and (make sure you have enough CP) then check the box next to it.
Then, to use it in game, you just press square immediately after the attack it is stemmed from. It's a pretty hard process of trial and error, because it is all about timing with that one. It took me a while to get used to doing it, but once I learned it is super easy and totally useful.
So, if I remember right, Omnislash 5 is stemmed from a slashing attack, right? It is an air attack, so press O from the air, and if you hit the person with it, as soon as it is over press square (you still have to be in the air for it to work), and it should branch into omnislash 5.
Good luck! I know it's hard at first.
And I totally agree about Cloud. He is my favorite character so far cause he is so versatile, despite being a little slower than some other characters. He has some really nice ranged attacks that stand to counter those spammy spells that characters like Terra and Ultimecia tend to do.
