Kingdom Hearts KH1 Final Mix Abilities

I'm trying to find out what ability you get from the Hercules Cup Time Trial. It references 30% and HP but the guide I've been using doesn't mention it and I can't think of an ability using HP and 30%

 

Could it be that your HP is boosted 30% when it is equipped?

 

perhaps.... Defence boost or something?

 

I think I figured it out. There is a move called Gravity Break that was listed as being the reward for Hades Cup Time Trial. I'm working on the Hades Time Trial now so we'll find out soon.

Edit: Yep. Hades timed gave me nothing but good old Save The King that, and I used gravity break in the tourny.

 

It's because Gravity Break has 30 % of hances of being used as a Finisher,and itdeals damage depending on the enemy HP.

I Remember there's another cup that gives a ability,not sure about which ability or cup tough,i think the ability is Ripple Drive.
And aqlso,Gravity Break has the same effect as Zantetsuken on Xemnas,it paralyzes him,but of course,Gravity break normally takes out like 1/2 of HP of a normal enemy,while Zantetsuken normally takes out 6/7.
But on higher level,both can be kill enemies in one single attack.
