Wild Pokémon
Each area below has its own table, split by encounter method. Standard rates merge every base slot for a species and are shown per time window: morning 04:00-09:59, day 10:00-19:59, night 20:00-03:59. Swarm, radio-broadcast, and Headbutt tables keep their own labeled rows, and every row carries HG/SS markers.
