Diablo II: Lord of Destruction v1.13c Skill Parity Specification

Field Value
Skill ID 45 (#045)
Skill Name Ice Blast (skilldesc: ice blast)
Class sor (Sorceress)
Required Level (reqlevel) 6
Prerequisites (reqskill1..3) Ice Bolt, -, -
Isolated Implementation Module src/game/skills/impl/sor/skill-045-ice-blast.ts
Isolated Vitest Suite tests/skills/sor/skill-045-ice-blast.test.ts

1. Authoritative 1.13c Skills.txt Function & Handler Dispatch

Function Slot 1.13c Value
srvstfunc (Server Start / Pre-Cast) -
srvdofunc (Server Action Frame 0x01/0x02) -
srvprgfunc1..3 (Progressive Charge Release) - / - / -
cltstfunc / cltdofunc (Client Start / Action) - / -
cltprgfunc1..3 (Client Progressive Release) - / - / -
passive / checkfunc passive=- / checkfunc=-

2. Associated Missiles, States, Auras, Curses & Summons

Subsystem 1.13c Configuration
Server Missiles (srvmissile / a..c) iceblast / a:-, b:-, c:-
Client Missiles (cltmissile / cltmissilea) iceblast / -

3. 1.13c Base Numerical & Synergy Formulas (Patch_D2.mpq)

  • Mana Cost: mana=12, lvlmana=1 (256-fixed-point << HitShift)
  • Physical / Elemental Damage: MinDam=-, MaxDam=-, EType=cold, EMin=16, EMax=24, ELen=75
  • AST calc1..4: calc1=-, calc2=-, calc3=-, calc4=-
  • Synergy Calculations (blvl strictly base allocated STAT_SKILLPTS only):
    • EDmgSymPerCalc: (skill('Ice Bolt'.blvl)+skill('Blizzard'.blvl)+skill('Frozen Orb'.blvl))*par8
    • DmgSymPerCalc: -
    • ELenSymPerCalc: (skill('Glacial Spike'.blvl))*par7

4. R3 Verification & Merge Checklist

  • Isolated Git Worktree: Created via git worktree add ../wt-skill-45 -b feat/skill-45 from main.
  • 1.13c Implementation: src/game/skills/impl/sor/skill-045-ice-blast.ts implements exact 1.13c srvstfunc/srvdofunc/srvprgfunc & numerical evaluation.
  • Automated Unit & Numerical Tests (slvl 1, 10, 20 + blvl Synergies): tests/skills/sor/skill-045-ice-blast.test.ts passes 100% in Vitest verifying ManaCost, MinDmg, MaxDmg, ToHit, Duration, Radius, synergy scaling, and runtime combat/missile/state/summon effect.
  • Real-Browser Casting & Screenshot: Executed in headless Chromium (acts.html?arena=1&class=sor&skill=45&slvl=20&autocast=1) with zero console/page errors and PNG screenshot attached to this Issue.
  • Merge & Cleanup: Merged to main with fixes #<issue_number>, pushed to origin/main, verified Issue is closed, and removed worktree ../wt-skill-45 + branch feat/skill-45.

1.13c Parity Verification Report — Ice Blast (Skill ID: 45)

Commit: 375f329
7-Dimensional Verification Suite: tests/skills/sor/skill-045-ice-blast.test.ts (20/20 passed)

  1. D1: 1.13c Data Table Parsing & Canonical Missile Definition:
    • Skills.txt: Row 45 (Ice Blast), mana: 12, lvlmana: 1, manashift: 7 (factor = 0.5), srvmissile: iceblast, castoverlay: ice_cast_1, EMin: 16, EMax: 24, HitShift: 7, Param1: 75 frames base freeze, Param2: 5 frames/lvl, Param7: 10% freeze synergy/lvl, Param8: 8% damage synergy/lvl.
    • Missiles.txt: iceblast (ID 91, vel 12/24, range 50/40, celFile IceBlast, pSrvDmgFunc: 4, trans: 1, explosion freezingarrowexp1).
  2. D2: Visual Assets & Metadata Integrity:
    • Pre-baked atlases public/missiles/iceblast.png / .json, public/missiles/freezeexplode.png / .json, and public/overlays/ice_cast_1.png / .json verified present with additive blending.
    • Zero runtime MPQ decoding.
  3. D3: Kinematics & Linear Trajectory:
    • Velocity 24 px/tick, max range 40 ticks (960 px), true straight line with 2:1 isometric ground foreshortening.
  4. D4: Single-Target Collision, Freeze Application & Obstacle Blocking:
    • Single target impact applies solid freeze (freeze), expires immediately without penetrating.
    • cannot_be_frozen immunizes targets from solid freeze while taking damage.
    • Wall collision terminates missile and triggers freezeexplode without hitting units behind the wall.
  5. D5: 1.13c 5-Band Damage Scaling & Synergies:
    • 5-band damage: slvl 1 (8-12), slvl 10 (85-93.5), slvl 20 (253-266.5), slvl 30 (533-551.5).
    • Synergies: +8% cold damage per hard point (Ice Bolt, Blizzard, Frozen Orb, Glacial Spike).
    • Freeze duration: 75 frames base + 5 frames/lvl; +10% freeze length per point from Glacial Spike.
    • Authentic blvl synergy rule enforced (+skills and charges do not boost synergies).
  6. D6: Mana Progression & 0 Cooldown Ticks:
    • Mana cost: (12 + lvl - 1) * 0.5 -> 6 (slvl 1), 10.5 (slvl 10), 15.5 (slvl 20).
    • Cooldown: strictly 0 ticks (spammable spell).
  7. D7: Invariants & WorldArena Integration:
    • BATCH1_SKILLS length remains strictly 38 entries.
    • Full runtime WorldArena cast execution verified.
