Spikes sets an entry hazard around the enemy team's field. Pokémon who switch into the spike-ridden field take 12.5% of their maximum HP in damage. Flying-type Pokémon are immune to this damage. The move Rapid Spin removes Spikes around the user.
Spikes can now be set up to three times, each increasing the damage done to the opponent upon switching in. One layer of Spikes will damage the opponent Pokémon by 1/8 (12.5%) of its maximum HP, two layers will deal 1/6 (16.67%), and three layers will deal 1/4 (25%). Any Pokémon with Levitate will also be immune to the damage.
Spikes creates a Spiked Tile underneath the user. Any Pokémon that steps on a Spiked Tile will lose 20 HP each. When this move is used by the player, the tile will remain hidden until a foe Pokémon steps on it; but if the move was used by a foe Pokémon, the player will be able to see it so it can be avoided at all times. However, Spiked Tile cannot be laid under one-tile ways and the entrance of a room.
