Psychic Terrain creates a low-lying psychic field lasting 5 turns, that prevents grounded Pokémon from being hit by high-priority moves (such as Quick Attack or Sucker Punch). The power of Psychic type moves also increases while in effect.

Grounded Pokémon are simply those that are not raised. Raised Pokémon are any Flying types or those under the effects of Levitate, Magnet Rise or Telekinesis. Full details in glossary.

Psychic Terrain is a terrain condition and can coexist at the same time as weather conditions, but not other terrain conditions.

The move Nature Power turns into Psychic under Psychic Terrain.

When a Pokémon is holding Psychium Z and uses its Z-Power, Psychic Terrain turns into Z-Psychic Terrain and raises Special Attack one stage, in addition to its usual effect as above.
