Grassy Terrain is a Grass-type move with no power or direct offensive capability and 100% accuracy. When used, it transforms the battlefield into grassy terrain for five turns. This terrain change restores the HP of all grounded Pokémon by 1/16th of their maximum HP at the end of each turn. Additionally, the power of Grass-type moves used by grounded Pokémon is boosted by 50%, while the damage from moves like Earthquake, Bulldoze, and Magnitude is halved. Grassy Terrain also prevents the activation of Seeds and certain Abilities while in effect. It is typically utilized to provide passive healing and enhance the effectiveness of Grass-type moves, making it a strategic asset in both single and double battles.
