Grass Pledge is a Grass-type special move with 80 power and 100% accuracy. It can be used in conjunction with either Fire Pledge or Water Pledge for additional effects. When used with Water Pledge, it creates a swamp on the opponent's side of the field that reduces the speed of all opposing Pokémon for four turns. When combined with Fire Pledge, it ignites a sea of fire on the opponent's side, dealing damage to all opposing Pokémon over four turns. Grass Pledge is particularly noted for its utility in double and triple battles, where its combination effects can provide valuable strategic advantages.
