Multivortex (マルチボーテックス Maruchibōtekkusu?) is a technique exclusive to Ventus in Kingdom Hearts Birth by Sleep and Kingdom Hearts Birth by Sleep Final Mix. The attack consists of quickly slicing the enemy with swift barrages of energy blades.
In Kingdom Hearts Birth by Sleep, Multivortex is Ventus's ultimate Shotlock that has a maximum level of 6 and max lock of 30. 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 in order to conjure up a gigantic whirlwind filled with stars that damages all the enemies in the area.
