Multivortex

Multivortex (マルチボーテックス) is a technique exclusive to Ventus in Kingdom Hearts Birth by Sleep. The attack consists of quickly slicing the enemy with swift barrages of blades of energy.

Mechanics
In Kingdom Hearts Birth by Sleep, Multivortex is Ventus' ultimate Shotlock. Once the attack has begun, the player can perform extra attacks by rotating the analog stick in a complete circle several times to spin in the air to conjure up a gigantic whirlwind filled with stars that damages all the enemies in the area.
