Rain Dish is an ability in the Pokémon series that provides the user with a distinct advantage during rainy weather conditions. Specifically, a Pokémon with Rain Dish will recover 1/16th of its maximum HP at the end of each turn while Rain Dance or any other rain-inducing effect, such as the move Drizzle, is active. This continuous HP recovery can significantly enhance the longevity and survivability of the Pokémon in battle, especially in conjunction with other rain-based strategies.
