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.

A phenomenon is an animated tile that may disappear when another area is entered. Repel can preserve movement safety but does not force a phenomenon to spawn.

Audino is common; rare evolved or otherwise unusual species occupy the remaining slots.
