Sand Veil is an ability found in certain Pokémon, primarily those of the Ground type. This ability increases the Pokémon's evasion by 20% during a sandstorm, making it harder for opponents to land their attacks. It is particularly useful in battles where sandstorm conditions are present, as it enhances the defensive capabilities of the Pokémon with this ability. The ability is commonly associated with Pokémon like Sandshrew and Gible. In competitive play, trainers often use Sand Veil in combination with moves or abilities that create a sandstorm, maximizing its effectiveness and providing a strategic advantage in battles.
