Mythical Pokémon Encounter Rate
Mythical Pokémon, as a whole, have a 1% encounter rate within their respective routes. For example, if Route 12 features Keldeo, Keldeo's encounter rate is 1%. On routes with multiple Mythical Pokémon, such as Isle of Armor, the overall encounter rate remains 1%. When this 1% chance is triggered, the game randomly selects which Mythical Pokémon to encounter. This 1% chance is not divided among the available Mythical Pokémon on that route.
