What is Vortex for Sora in Kingdom Hearts

In Kingdom Hearts, It's an ability that can be equipped to Sora for 1 AP. When equipped and Sora attacks while on the ground a slight distance from an enemy, he will do a spinning slash that moves him closer. This ability behaves as the first attack in combo string. This ability can be boosted with Berserk.

In Kingdom Hearts II, this is replaced with the superior Slide Dash ability (not a Finishing Move) which can be equipped for 2 AP. Slide Dash performs the same function as Vortex without the slight delay and fair chance to miss. This ability can be boosted with Berserk Charge.

Slide Dash can also be used as a normal attack by Sora in Valor Form even though Valor Form comes with the Over the Horizon ability which fulfills the same purpose and is easier to perform repeatedly.
