Return to the restored lakes, catch stationary Uxie and Azelf, and release roaming Mesprit while tracking its changing route. This standalone section joins the route plan to the original Diamond/Pearl map, encounter, trainer, item, and script data; Platinum tables are not substituted.
Source maps
Verity Cavern, Lake Valor, Valor Cavern, Lake Acuity, and Acuity Cavern.
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
Visit Lake Valor and save before Azelf; visit Lake Acuity and save before Uxie; visit Lake Verity and interact with Mesprit; obtain the Marking Map app if missed; choose a route-boundary tracking loop; use trapping or Mean Look plus status for Mesprit.
- Mesprit flees immediately from ordinary encounters while retaining damage and status between meetings. Its position changes when the player changes routes and can jump on Fly.
- Uxie and Azelf are stationary one-time encounters in their caverns; save separately before each.

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.
No trainer object, scripted battle, or assigned boss team is sourced for this section.
Items
| Item | Version | Type | Area / exact direction | Coordinate / script | Requirement | Source |
|---|---|---|---|---|---|---|
| TM25 | Diamond / Pearl | Visible item ball | Lake Valor: On the restored Lake Valor water route; the drained Galactic-state object shares the same one-time pickup flag and is not a second copy. | (53, 46) | Relic Badge and Surf, plus completion of the Spear Pillar crisis so Lake Valor is restored. | event bank 302, script 7156 |
Hidden Items
No type-2 hidden-item event is present in the source maps assigned to this section.
Puzzles, Warps, And Switches
- For Mesprit, stand at a boundary between two routes with nearby grass, cross until its Marking Map icon matches the player's route, then enter grass without Flying.
- A lead with Mean Look, Block, Spider Web, Arena Trap where applicable, or a fast sleep move makes the roaming capture far more controlled.
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: Visit Lake Valor and save before Azelf; visit Lake Acuity and save before Uxie; visit Lake Verity and interact with Mesprit; obtain the Marking Map app if missed; choose a route-boundary tracking loop; use trapping or Mean Look plus status for Mesprit.
- Review all 19 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.
Sources And Validation
pret/pokediamondat commit038cccaed5de8f013875bc5d734f912d1de08e0f:map_header.c, D/P encounter archives,trdata.json, zone events, script archives, item tables, and trainer graphics.- Encounter slots were decoded from exact 424-byte D/P members and cross-checked against Gen IV slot behavior; the 0x6C pair is day, morning uses base slots, and 0x74 is night.
- 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.
