Gradually regains HP in rain.
Rain Dish is an ability that allows the Pokémon to recover 1/16 of its maximum HP at the end of each turn if it is raining. This makes Rain Dish a very useful ability for Pokémon that are used in rain teams, as they can sustain themselves and stay in battle longer while the weather condition is active.
