Vit 0 is a status in Final Fantasy VIII. Units afflicted by Vit 0 have their Vitality and Spirit stats set to 0, rendering them extremely vulnerable to both physical and magical attacks. The effect remains indefinitely until healed, even outside of battle, but only few enemies will use this status against the player.
Inflicting enemies with Vit 0 lets the player do maximum damage against them more easily, and it is best done as the first move in any given tough battle. Those afflicted with Vit 0 turn into a purple hue. All enemies can be inflicted with Vit 0, making it one of the most useful effects in the game. Unusually, Vit 0 cannot be used in ST-Atk-J nor ST-Def-J.
