Version discipline
Rows merge only when Diamond and Pearl are identical, and each row carries D/P game markers. Version-exclusive species, mascot encounters, swarms, Radar slots, and GBA insertion slots keep their own labeled rows.
Route Plan
Use the Bicycle slope from Oreburgh; collect the Vs. Seeker and Dowsing Machine; sweep Route 207 trainers; enter Mt. Coronet; follow the ground-level east passage; watch the Cyrus scene; exit to Route 208.
- The Dowsing Machine Poketch app is central to the walkthrough's hidden-item directions; activate it when entering each new map.
- Most visible Mt. Coronet branches remain gated by Surf, Strength, Rock Climb, or Waterfall and must be labeled for later phases.

Trainers
Field order follows the map's object-event order. Full teams include explicit held items and moves when trdata defines them; cash rewards use the in-engine final-party-slot level and trainer-class multiplier formula.

Puzzles, Warps, And Switches
- On the first crossing, stay on the lowest eastbound cave path. Do not treat visible upper ledges or water as missed content; they form later ascent routes.
Boss Strategy And Partners
No Gym Leader, rival branch, Galactic boss, Elite Four member, Champion, story partner, or major postgame battle is assigned here.
Completion Checklist
- Complete the currently reachable part of this route plan: Use the Bicycle slope from Oreburgh; collect the Vs. Seeker and Dowsing Machine; sweep Route 207 trainers; enter Mt. Coronet; follow the ground-level east passage; watch the Cyrus scene; exit to Route 208.
- Review all 21 encounter rows across the per-area tables, including game markers, method band, time-of-day rates, levels, and each conditional requirement; mark conditional rows for their stated revisit.
- Defeat or deliberately skip every currently reachable trainer row; leave HM-, story-, or National-Dex-gated rows checked only after their access requirement is met.
- Collect currently reachable visible/scripted items and berry trees, use the Dowsing Machine for reachable hidden rows, and retain every explicitly gated row for the named cleanup visit.
- Resolve every currently available puzzle note, boss branch, and partner scene before opening the next section.

- Coordinates remain visible as QA anchors, while each hidden row also provides a plain-English map-region instruction.
- Generation-wide systems that are not tied to a normal map archive—Honey Trees, Great Marsh daily rolls, Trophy Garden, fossils, Pal Park, and event items—are explicitly curated in their dedicated system pages.
