Ruination is a Dark-type move introduced in Pokémon Scarlet and Violet. Ruination has no base power but instead deals damage equal to 50% of the target's current HP, making it an effective move for whittling down foes with high HP. The accuracy of Ruination is 90%. The move does not inflict any status ailments but is notable for its ability to consistently halve the target's health, making it useful in various strategic scenarios, especially against bulky opponents. Ruination is particularly favored in battles where wearing down the opponent's strength is crucial.
