Walkthrough

  1. Set the route. Read the item requirements below before entering; bring Surf, Strength, Waterfall, or the Dowsing Machine when a source direction names it.
  2. Clear in order. Battle the listed trainers from top to bottom, healing before any boss card or required story fight.
  3. Sweep the map. Collect visible items first, then make a second Dowsing Machine pass for every hidden tile.
  4. Finish the table. Apply the version and season filters before hunting; time of day never changes Black/White wild slots.

Pokémon locations

Each area below has its own table, split by encounter method. Rates merge every slot for a species and are shown per season; a single centered rate means all four seasons match. Time of day never changes Black/White wild slots. Identical Black and White slots share one row with both game markers.
