Walkthrough

  1. Advance the objective. Follow the section summary and finish required rival, Plasma, Gym, or League battles first.
  2. Sweep trainers and items. Use the tables below in map order, then make a separate Dowsing Machine pass.
  3. Set the right filters. Black 2 and White 2 diverge in encounter slots, routes, facilities, and key unlocks; difficulty modes keep distinct boss records.
  4. Close optional loops. Check Hidden Grottoes, weekday statics, seasonal access, gifts, and postgame prerequisites before leaving.
