Phase 7 Icicle Badge The three lakes, Mt. Coronet, Routes 216 and 217, Snowpoint City, Candice, and Lake Acuity. 07 / 11 
Use Strength through the mountain's northern rooms and emerge on the frozen road to Snowpoint. 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
Mount Coronet North 1F Room 2 and Mount Coronet North 1F Room 1.
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
Enter Mt. Coronet from Route 211 East; push Strength boulders only after collecting nearby items; clear cave trainers; use Rock Smash side pockets; follow the northern exit; verify no boulder blocks the return path; step onto Route 216.
- This is the Snowpoint transit passage, not the Spear Pillar ascent. Rock Climb remains unavailable until Candice is defeated.
- Strength boulders remain in their moved positions until the map reloads, so a mistaken push can be reset by leaving and re-entering.

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.

Puzzles, Warps, And Switches
- Push boulders from the side that preserves access to item alcoves. If a boulder is pinned against a wall before its branch is cleared, reload the room and redo the push sequence.
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: Enter Mt. Coronet from Route 211 East; push Strength boulders only after collecting nearby items; clear cave trainers; use Rock Smash side pockets; follow the northern exit; verify no boulder blocks the return path; step onto Route 216.
- Review all 13 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.
