Terrain (Japanese: フィールド field) is a type of field effect in the Pokémon games that affects Pokémon on the ground. The mechanic was introduced in Generation VI. In battle, there is always initially no terrain, but it can be changed by Pokémon's moves and Abilities. Only one type of terrain may be present at a time, with any new terrain put in place overwriting the previous terrain.

In the games

There are four types of terrain: Electric Terrain, Grassy Terrain, Misty Terrain, and Psychic Terrain.

Causing terrain

Each terrain has a corresponding move and Ability that will create it.

Terrain normally lasts for 5 turns regardless of how it is created, but if the Pokémon with that move or Ability held a Terrain Extender when the terrain was put into effect, it lasts 8 turns.

Effects

• Electric Terrain: Increases the power of Electric-type moves used by Pokémon on the ground by 50%. Prevents Pokémon on the ground from falling asleep and being afflicted by Yawn.
• Grassy Terrain: Increases the power of Grass-type moves used by Pokémon on the ground by 50%. Restores 1/16 HP to all Pokémon on the ground each turn. Halves the damage taken from Bulldoze, Earthquake, and Magnitude.
• Misty Terrain: Halves the damage taken from Dragon-type moves used by Pokémon on the ground. Prevents Pokémon on the ground from being afflicted with status conditions; in Generation VII, also protects from confusion.
• Psychic Terrain: Increases the power of Psychic-type moves used by Pokémon on the ground by 50%. Prevents Pokémon on the ground from being hit by moves with increased priority.

Pokémon that are in the semi-invulnerable turn of a move are considered to not be on the ground for the purposes of terrain.

The Ability Grass Pelt increases the Pokémon's Defense by 50% during Grassy Terrain. The Ability Surge Surfer increases the Pokémon's Speed by 100% during Electric Terrain.

Natural objects disappear and cannot be destroyed while terrain is in effect.

Items

If a Pokémon is holding one of these four held items when the appropriate terrain is created, or switches in while the appropriate terrain is in effect, the item will be consumed and boost one of the holder's stats by one stage. The item will activate regardless of whether or not the Pokémon is grounded.

Environment-based moves

Terrain causes moves that vary with environment to ignore the current location and determine their effect based on the terrain, regardless of whether the move's user is on the ground.
