Phase 7 Icicle Badge The three lakes, Mt. Coronet, Routes 216 and 217, Snowpoint City, Candice, and Lake Acuity. 07 / 11 
Enter the drained lake, defeat Galactic forces among stranded Magikarp, and confront Saturn inside Valor Cavern. 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
Lake Valor Galactic.
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
Fly to Pastoria or Valor Lakefront; enter the now-open lake; clear every Grunt around the basin; collect reachable items; enter Valor Cavern; heal and save; defeat Saturn; leave for Twinleaf and Lake Verity.
- The drained-lake map is separate from the restored post-Spear-Pillar lake, so its Grunts and items must not be merged with the later Azelf visit.
- Saturn's Toxicroak has strong offensive coverage; Ground, Flying, and Psychic attacks are the cleanest direct answers.

Wild Pokémon
No random wild encounter archive or curated static/gift row applies to this section. This is expected for some buildings, story rooms, and Gym interiors.
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
- Walk the dry channels in a full perimeter before entering the cavern. Several Grunts stand on isolated banks that are easy to skip when following the center path.

Danger notes
Toxicroak is Saturn's finisher and can exploit Water attacks through Dry Skin.
Practical counters
Psychic is four-times effective and Ground is also strong; do not feed it Water recovery.
Completion Checklist
- Complete the currently reachable part of this route plan: Fly to Pastoria or Valor Lakefront; enter the now-open lake; clear every Grunt around the basin; collect reachable items; enter Valor Cavern; heal and save; defeat Saturn; leave for Twinleaf and Lake Verity.
- Review all 0 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.
