From Bulbapedia, the community-driven Pokémon encyclopedia.
Psychic Terrain (Japanese: サイコフィールド Psycho Field) is a non-damaging Psychic-type move introduced in Generation VII. It is TM91 in Generation VIII.
Psychic Terrain creates terrain that envelops the field and replaces the background environment and any other terrain that is already in effect. The terrain fades after five turns.
This terrain has the following effects on Pokémon that are on the ground and not in the semi-invulnerable turn of a move.
When a Pokémon with the Ability Psychic Surge enters battle, Psychic Terrain is automatically created. Upon successfully doing damage, Genesis Supernova creates Psychic Terrain on the field.
If a Pokémon is holding a Psychic Seed while the field is Psychic Terrain, it consumes the Psychic Seed and its Special Defense is increased by one stage (even if it is not otherwise affected by the terrain). If a Terrain Extender is held when Psychic Terrain is used, the terrain will last 8 turns instead of 5.
If powered up by a Psychium Z into Z-Psychic Terrain, the user's Special Attack stat rises by one stage.
Psychic Terrain now:
Psychic Terrain is automatically created when Max Mindstorm is used.
| This protects Pokémon on the ground from priority moves and powers up Psychic-type moves for five turns.
