Terrain

Terrain is a type of field effect that affects Pokémon on the ground. In battle, there is often no initial 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.

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

Causing terrain

Each terrain has a corresponding move, Max Move, and Ability that will create it. Psychic Terrain can be invoked by a certain Z-Move as well.

	Electric Terrain	Grassy Terrain	Misty Terrain	Psychic Terrain
Terrain move	Electric Terrain	Grassy Terrain	Misty Terrain	Psychic Terrain
Z-Move / Max Move	Max Lightning	Max Overgrowth	Max Starfall	Genesis Supernova Max Mindstorm
Ability	Electric Surge	Grassy Surge	Misty Surge	Psychic Surge

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.

Removing terrain

Terrain can be removed using certain moves.
