Psychic Terrain

Lasts 5 turns (8 with Terrain Extender). Psychic-type moves used by grounded Pokémon deal 1.3× damage. Grounded Pokémon can't be hit by the opponents' priority moves (e.g. Fake Out, Sucker Punch, Extreme Speed, or Prankster status moves).

Only one terrain can be active at a time: a new one replaces the old one. "Grounded" means not Flying-type and without Levitate or Air Balloon.
