Spirit Shackle is a Ghost-type move with 80 power and 100% accuracy. It has the unique effect of preventing the target from switching out or fleeing. Spirit Shackle is the signature move of Decidueye, one of the final evolutions of the Grass-Ghost starter Pokémon from the Alola region. This move is particularly useful in competitive play for trapping opponents, making it hard for them to escape unfavorable matchups. Additionally, Spirit Shackle benefits from Decidueye's high Attack stat, allowing it to deal significant damage while also providing strategic utility.
