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 SecretPotion on the Psyduck; accept Cynthia's Old Charm; teach Defog if desired; clear the lower grass; use Defog in the northern section; cross Bicycle rails; defeat every Ninja Boy and Ace Trainer; enter Celestic.
- Fog lowers move accuracy in battle and obscures navigation. Defog is optional mechanically but strongly recommended for a clean trainer sweep.
- Grandma Wilma teaches Draco Meteor to a sufficiently friendly Dragon-type in her house near the northern route.

Puzzles, Warps, And Switches
- Some narrow rails require the Bicycle and exact alignment. Clear the ground-level grass branches before committing to the elevated rail route toward Celestic.
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 SecretPotion on the Psyduck; accept Cynthia's Old Charm; teach Defog if desired; clear the lower grass; use Defog in the northern section; cross Bicycle rails; defeat every Ninja Boy and Ace Trainer; enter Celestic.
- Review all 18 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.
