Phase 7 Icicle Badge The three lakes, Mt. Coronet, Routes 216 and 217, Snowpoint City, Candice, and Lake Acuity. 07 / 11 
Use Rock Climb into Lake Acuity, witness the aftermath of Barry's defeat, and watch Jupiter withdraw to Veilstone without a player battle. 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 Acuity 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
Leave Snowpoint west; Rock Climb at Acuity Lakefront; enter the Galactic lake state; approach Barry and Jupiter; watch Jupiter taunt Barry and leave; collect available items; Fly to Veilstone for the Galactic HQ raid.
- Original Diamond and Pearl contain no player-versus-Jupiter battle at Lake Acuity. Trainer ID 407 belongs to the later Spear Pillar tag battle and must not be attached to this scene.
- Do not substitute Platinum's expanded lake dialogue or Distortion World setup. Diamond and Pearl send the player directly toward Galactic HQ.

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 |
|---|---|---|---|---|---|---|
| TM14 | Diamond / Pearl | Visible item ball | Lake Acuity Galactic: Across Lake Acuity's northeast water during the Jupiter story visit; the normal-state object is an alias of this same one-time pickup. | (38, 8) | Relic Badge and Surf, plus access to Lake Acuity after the Icicle Badge route. | event bank 305, script 7177 |
Hidden Items
No type-2 hidden-item event is present in the source maps assigned to this section.
Puzzles, Warps, And Switches
- The Rock Climb wall is immediately west of Snowpoint on Acuity Lakefront. After climbing, the lake path is linear to Barry's scene.
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: Leave Snowpoint west; Rock Climb at Acuity Lakefront; enter the Galactic lake state; approach Barry and Jupiter; watch Jupiter taunt Barry and leave; collect available items; Fly to Veilstone for the Galactic HQ raid.
- Review all 17 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.
