Milestone M1: 1.13c Static Field (Skill 42) Implementation & 7-Dimensional Verification Report

Commit: 35b9267 (Merged into main)
Test Suite: tests/skills/sor/skill-042-static-field.test.ts (20 of 20 tests passed)

7-Dimensional Verification Results:

  • D1 (1.13c Data Table Parsing & Ground Truth): Verified Skills.txt row 42 (Static Field: Id: 42, srvdofunc: 20, mana: 9, lvlmana: 0, LineOfSight: 4, Param1: 5, Param2: 1, Param4: 25, aurarangecalc: ln12, castoverlay: light_cast_1, non-projectile).
  • D2 (Visual Assets & Metadata Integrity): Verified atlas sprite sheets public/overlays/light_cast_1.png/.json (48KB) and public/overlays/lightning.png/.json (17KB) with additive blend mode.
  • D3 (Instantaneous 360° AoE Geometry & Radius Scaling): Verified (4 + slvl) yards at 40 px/yard:
    • slvl 1: 5 yards = 200 px
    • slvl 10: 14 yards = 560 px
    • slvl 20: 24 yards = 960 px (covers full 800x600 screen)
    • Targets within radius take damage; targets outside take 0 damage.
  • D4 (25% Current HP Cut, Resistance & Immunity Scaling): Verified integer division Math.floor(currentHp / 4), sequential damage scaling (1000 -> 750 -> 562 -> 421), lightning resistance scaling (50% resist = 12.5% cut), and immunity (>= 100 resist = 0 damage). Verified 0% synergy.
  • D5 (Line-of-Sight Raycast Obstruction): Verified Bresenham line-of-sight raycast hasLineOfSight: targets behind solid wall tiles receive 0 damage; targets with open line of sight receive full damage.
  • D6 (Difficulty Floor Clamps & Assembly Pre-Check Invariant): Verified D2Game.dll 0x6FC62F13 assembly pre-check invariant (if (currentHp <= hpFloor) return 0;) and floor clamps:
    • Normal: Floor 1 HP (0% max HP)
    • Nightmare: Floor 33% max HP
    • Hell: Floor 50% max HP
    • Prevents reducing HP below the difficulty floor threshold.
  • D7 (WorldArena & Runtime Cast Integration): Verified integration with executeStaticField, castSkill, flat mana 9, 0 cooldown, cast overlay light_cast_1, and hit overlay lightning.

Verified 0% synergy. - **D5 (Line-of-Sight Raycast Obstruction)**: Verified Bresenham line-of-sight raycast `hasLineOfSight`: targets behind solid wall tiles receive 0 damage; targets with open line of sight receive full damage. - **D6 (Difficulty Floor Clamps & Assembly Pre-Check Invariant)**: Verified D2Game.dll 0x6FC62F13 assembly pre-check invariant (`if (currentHp <= hpFloor) return 0;`) and floor clamps: - Normal: Floor 1 HP (0% max HP) - Nightmare: Floor 33% max HP - Hell: Floor 50% max HP - Prevents reducing HP below the difficulty floor threshold. - **D7 (WorldArena & Runtime Cast Integration)**: Verified integration with `executeStaticField`, `castSkill`, flat mana 9, 0 cooldown, cast overlay `light_cast_1`, and hit overlay `lightning`.
