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

Field Value
Skill ID 25 (#025)
Skill Name Plague Javelin (skilldesc: plague javelin)
Class ama (Amazon)
Required Level (reqlevel) 18
Prerequisites (reqskill1..3) Lightning Bolt, -, -
Isolated Implementation Module src/game/skills/impl/ama/skill-025-plague-javelin.ts
Isolated Vitest Suite tests/skills/ama/skill-025-plague-javelin.test.ts

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

Function Slot 1.13c Value
srvstfunc (Server Start / Pre-Cast) 4
srvdofunc (Server Action Frame 0x01/0x02) -
srvprgfunc1..3 (Progressive Charge Release) - / - / -
cltstfunc / cltdofunc (Client Start / Action) 11 / -
cltprgfunc1..3 (Client Progressive Release) - / - / -
passive / checkfunc passive=- / checkfunc=-
auraevent1 / auraeventfunc1 - / -

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

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

Passive State & Stats (passivestate / passivestat1..3) state:- / -, -, -
Curse Priority (cursetype) -
Summon / Pet (summon / pettype / petmax) mon:- / type:- / max:-

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

  • Mana Cost: mana=14, lvlmana=1 (256-fixed-point << HitShift)
  • Physical / Elemental Damage: MinDam=-, MaxDam=-, EType=pois, EMin=10, EMax=16, ELen=75
  • AST calc1..4: calc1=-, calc2=-, calc3=-, calc4=-
  • Synergy Calculations (blvl strictly base allocated STAT_SKILLPTS only):
    • EDmgSymPerCalc: (skill('Poison Javelin'.blvl))*par8
    • DmgSymPerCalc: -
    • ELenSymPerCalc: -

4. R3 Verification & Merge Checklist

  • Isolated Git Worktree: Created via git worktree add ../wt-skill-25 -b feat/skill-25 from main.
  • 1.13c Implementation: src/game/skills/impl/ama/skill-025-plague-javelin.ts implements exact 1.13c srvstfunc/srvdofunc/srvprgfunc & numerical evaluation.
  • Automated Unit & Numerical Tests (slvl 1, 10, 20 + blvl Synergies): tests/skills/ama/skill-025-plague-javelin.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=ama&skill=25&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-25 + branch feat/skill-25.
