Spikes is a status move of the Ground-type category. It has no power or accuracy parameters as it doesn't deal direct damage. When used, it lays a hazard on the opponent's side of the field that damages any Pokémon that switches in, except Flying-type Pokémon or those with the Levitate ability. Up to three layers of Spikes can be set, with each layer increasing the damage taken by switching-in Pokémon: 1 layer deals 12.5% of maximum HP, 2 layers deal 16.67%, and 3 layers deal 25%. Spikes are commonly used in competitive play to apply continuous pressure on the opposing team and force switches.
