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

Field Value
Skill ID 49 (#049)
Skill Name Lightning (skilldesc: lightning)
Class sor (Sorceress)
Required Level (reqlevel) 12
Prerequisites (reqskill1..3) Charged Bolt, -, -
Isolated Implementation Module src/game/skills/impl/sor/skill-049-lightning.ts
Isolated Vitest Suite tests/skills/sor/skill-049-lightning.test.ts

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

Function Slot 1.13c Value
srvstfunc (Server Start / Pre-Cast) -

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

Subsystem 1.13c Configuration
Server Missiles (srvmissile / a..c) lightningbolt / a:-, b:-, c:-
Client Missiles (cltmissile / cltmissilea) lightningbolt / -
Aura / Buff States (aurastate / auratgtstate) self:- / tgt:-

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

  • Mana Cost: mana=16, lvlmana=1 (256-fixed-point << HitShift)
  • Physical / Elemental Damage: MinDam=-, MaxDam=-, EType=ltng, EMin=1, EMax=40, ELen=-
  • AST calc1..4: calc1=-, calc2=-, calc3=-, calc4=-
  • Synergy Calculations (blvl strictly base allocated STAT_SKILLPTS only):
    • EDmgSymPerCalc: (skill('Charged Bolt'.blvl)+skill('Chain Lightning'.blvl)+skill('Nova'.blvl))*par8
    • DmgSymPerCalc: -
    • ELenSymPerCalc: -

4. R3 Verification & Merge Checklist

  • Isolated Git Worktree: Created via git worktree add ../wt-skill-49 -b feat/skill-49 from main.
  • 1.13c Implementation: src/game/skills/impl/sor/skill-049-lightning.ts implements exact 1.13c srvstfunc/srvdofunc/srvprgfunc & numerical evaluation.
  • Automated Unit & Numerical Tests (slvl 1, 10, 20 + blvl Synergies): tests/skills/sor/skill-049-lightning.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=49&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-49 + branch feat/skill-49.
