Vertical Slice (also referred to V-Slice or simply VS) is a very powerful battle skill used in The Last Story. In Story Mode, only Zael, Dagran, and Syrenne can use it. To V-Slice, one must run up to a wall and select a place to perform the attack, once done, the character will jump off the wall and slam onto the dsignated area, dealing major damage.
Like Slash, it does not use the Command Guage. It also deals 3x damage of the user's regular attack.
