1.3 权威 64 点离散圆周坐标表 (D2Game.dll VA 0x6FD1C960, 0x6FD1CA60)

原版暴风雪落点通过 64 点离散圆周表计算方位，半径为 30 subtiles：

export const BLIZZARD_CIRCLE_X = [
  0, 2, 5, 8, 11, 14, 16, 19,
  21, 23, 24, 26, 27, 28, 29, 29,

  -30, -29, -29, -28, -27, -26, -24, -23,
  -21, -19, -16, -14, -11, -8, -5, -2
] as const;

export const BLIZZARD_CIRCLE_Y = [
  30, 29, 29, 28, 27, 26, 24, 23,

  • 2:1 二等角投影大地缩放： 
    X_{\text{offset}} = \frac{X_{\text{tbl}} \times 7}{30} + \text{jitter}_x
    Y_{\text{offset}} = \left(\frac{Y_{\text{tbl}} \times 7}{30} + \text{jitter}_y\right) \times 0.5

2. 数学公式与机制规则

  1. 法力消耗公式： 
    \text{ManaCost}(\text{slvl}) = 23 + (\text{slvl} - 1) \times 1
    • slvl 1: 23 点法力
    • slvl 10: 32 点法力
    • slvl 20: 42 点法力
  2. 5 阶段基础冰霜伤害公式 (D2Common.dll 0x6FDB9DDE)：
    • Band 1 (slvl 1–8): Min 45 + (\text{slvl}-1) \times 15, Max 75 + (\text{slvl}-1) \times 16
    • Band 2 (slvl 9–16): Min 150 + (\text{slvl}-8) \times 30, Max 187 + (\text{slvl}-8) \times 31
    • Band 3 (slvl 17–22): Min 390 + (\text{slvl}-16) \times 45, Max 435 + (\text{slvl}-16) \times 46
    • Band 4 (slvl 23–28): Min 660 + (\text{slvl}-22) \times 55, Max 711 + (\text{slvl}-22) \times 56
    • Band 5 (slvl 29+): Min 990 + (\text{slvl}-28) \times 65, Max 1047 + (\text{slvl}-28) \times 66
    • 基准伤害值：
      • slvl 1: 45 – 75
      • slvl 10: 210 – 249
      • slvl 20: 570 – 619
      • slvl 30: 1120 – 1179
  3. 协同加成 (Synergies)： 
    \text{Multiplier} = 1 + (\text{blvl}_{\text{Ice Bolt}} + \text{blvl}_{\text{Ice Blast}} + \text{blvl}_{\text{Glacial Spike}}) \times 0.05
    • 投入 20 点纯基础点数：1 + 20 \times 0.05 = 2.0\times (+100% 冰霜伤害)
    • 满协同 60 点：1 + 60 \times 0.05 = 4.0\times (+300% 冰霜伤害)
  4. NextDelay = 0 铁律：
    • Missiles.txt 中 Blizzard 投射物与爆炸的 NextDelay 均为 0（无全局受击无敌帧）。
    • 多个落冰重叠时可对大型目标连续独立造成全额杀伤。

3. 资产与离线烘焙规划 (Zero Runtime MPQ Invariant)

  1. DCC 提取与 PNG 烘焙清单：
    • blizzard1: data/global/missiles/icestormfallvar01.dcc (6 帧, 512x198, Trans: 1)
    • blizzard2: data/global/missiles/icestormfallvar02.dcc (6 帧, 512x195, Trans: 1)
    • blizzard3: data/global/missiles/Blizzard.dcc (8 帧, 512x307, Trans: 1)
    • blizzardexplode1: data/global/missiles/icestormimpactvar01.dcc (6 帧, 512x145, Trans: 1)
    • blizzardexplode2: data/global/missiles/icestormimpactvar02.dcc (6 帧, 512x141, Trans: 1)
  2. 别名映射：
    • blizzard4 -> blizzard3
    • blizzardexplode3 -> blizzardexplode2
  3. 施法覆盖层：
    • ice_cast_3 已经预烘焙于 public/overlays/ice_cast_3.png，直接复用 ICE_CAST_3_META。
  4. 渲染混合：
    • 全体暴风雪投射物与爆炸帧统一采用 Trans: 1 加色混合 (ctx.globalCompositeOperation = "lighter")。

4. 7 维全覆盖验证验收清单 (Acceptance Criteria)

  • 维度 1：静态数据真值校验 (Skills.txt ID 59, Missiles.txt ID 158-165, delay 45, duration 100, radius 7)
  • 维度 2：烘焙资产与别名完整性 (blizzard1..3, blizzardexplode1..2 存在于 public/missiles/, 别名映射正确, Trans: 1 加色混合)
  • 维度 3：控制器步进与时序 (100 刻总时长, 每 4 刻生成 1 枚落冰, 合计恰好 25 枚落冰)
  • 维度 4：64 点离散圆周与 2:1 椭圆修正 (严格采用 64 点表, Y 分量乘入 0.5 椭圆地面修正)
  • 维度 5：下落弹道与触地爆炸 (120px 屏幕高程, 9 刻降落至 0, 碰撞或终点派生 blizzardexplode)
  • 维度 6：5 阶伤害与协同公式 (slvl 1/10/20/30 精确匹配 45-75/210-249/570-619/1120-1179, 协同 +5%/点)
  • 维度 7：NextDelay = 0 杀伤判定 (多枚冰雹重叠命中同一目标全部计入全额伤害, 0 免疫帧)

Blizzard (Skill #059) Implementation & Verification Complete

Status: Merged to main (commit 39de193) and verified across all dimensions.

1. Diablo II v1.13c Ground Truth Parity

  • 5-Band Damage Formula: Implemented exact 1.13c level scaling (D2Common.dll 0x6FD9DDB0 & 0x6FDBA580) across all 5 bands ([1..8], [9..16], [17..22], [23..28], [29+]) and +5%/point hard synergies (blvl only per 1.13c synergy rules).
  • Controller & Falling Shards: Missiles 158 (blizzardcenter), 159–162 (blizzard1–blizzard4), and 163–165 (blizzardexplode1–blizzardexplode3).
  • Cadence & Trajectory: 25 shards dropped over 100 ticks (cadence 4, step 13 mod 64) with 2:1 isometric aspect ratio scaling (ISO_GROUND_ASPECT_RATIO = 0.5) referencing the authoritative 64-entry circle table from D2Game.dll (0x6FD1C960 & 0x6FD1CA60).
  • NextDelay Invariant: NextDelay = 0 allowing overlapping shard sweet-spot bursts without temporary hit immunity.
  • CelFile Alignment: Corrected CANONICAL_113C_MISSILES.blizzardexplode3.celFile to icestormimpactvar02.
  • Damage Routing: Eliminated silent fallback; shards strictly inherit evaluated controller damage.

2. Asset Baking (Zero Runtime MPQ Invariant)

  • Baked blizzard1.png / blizzard2.png / blizzard3.png / blizzard4.png and JSON metadata to public/missiles/.
  • Baked blizzardexplode1.png / blizzardexplode2.png / blizzardexplode3.png and JSON metadata to public/missiles/.
  • Exported TypeScript metadata definitions in src/render/missiles-meta.ts.

3. Verification & Quality Gate Results

  • TypeScript Typecheck: Passed cleanly with 0 errors (npm run typecheck).
  • Dedicated Unit Tests: 16/16 passed (tests/skills/sor/skill-059-blizzard.test.ts & tests/blizzard-missile-113c.test.ts).
  • Challenger & Stress Tests: 24/24 passed (tests/blizzard-challenger-stress.test.ts & tests/blizzard-stress.test.ts).

### Blizzard (Skill #059) Implementation & Verification Complete **Status**: Merged to `main` (commit `39de193`) and verified across all dimensions. #### 1. Diablo II v1.13c Ground Truth Parity - **5-Band Damage Formula**: Implemented exact 1.13c level scaling (`D2Common.dll` 0x6FD9DDB0 & 0x6FDBA580) across all 5 bands ([1..8], [9..16], [17..22], [23..28], [29+]) and +5%/point hard synergies (`blvl` only per 1.13c synergy rules). - **Controller & Falling Shards**: Missiles 158 (`blizzardcenter`), 159–162 (`blizzard1`–`blizzard4`), and 163–165 (`blizzardexplode1`–`blizzardexplode3`). - **Cadence & Trajectory**: 25 shards dropped over 100 ticks (cadence 4, step 13 mod 64) with 2:1 isometric aspect ratio scaling (`ISO_GROUND_ASPECT_RATIO = 0.5`) referencing the authoritative 64-entry circle table from `D2Game.dll` (0x6FD1C960 & 0x6FD1CA60). - **NextDelay Invariant**: `NextDelay = 0` allowing overlapping shard sweet-spot bursts without temporary hit immunity. - **CelFile Alignment**: Corrected `CANONICAL_113C_MISSILES.blizzardexplode3.celFile` to `icestormimpactvar02`. - **Damage Routing**: Eliminated silent fallback; shards strictly inherit evaluated controller damage. #### 2. Asset Baking (Zero Runtime MPQ Invariant) - Baked `blizzard1.png` / `blizzard2.png` / `blizzard3.png` / `blizzard4.png` and JSON metadata to `public/missiles/`. - Baked `blizzardexplode1.png` / `blizzardexplode2.png` / `blizzardexplode3.png` and JSON metadata to `public/missiles/`. - Exported TypeScript metadata definitions in `src/render/missiles-meta.ts`. #### 3. Verification & Quality Gate Results - **TypeScript Typecheck**: Passed cleanly with **0 errors** (`npm run typecheck`). - **Dedicated Unit Tests**: **16/16 passed** (`tests/skills/sor/skill-059-blizzard.test.ts` & `tests/blizzard-missile-113c.test.ts`). - **Challenger & Stress Tests**: **24/24 passed** (`tests/blizzard-challenger-stress.test.ts` & `tests/blizzard-stress.test.ts`). - 100,000-tick continuous simulation passed (2,223 casts, 10,653 hits, bounded heap +12.23 MB, 0 NaNs, 0 leaks). - **Forensic Auditor**: **CLEAN** (`teamwork_preview_auditor_blizzard`). - **Reviewers**: **APPROVE** (`teamwork_preview_reviewer_blizzard_verify`, `teamwork_preview_reviewer_blizzard_2`). - **Challengers**: **APPROVE** (`teamwork_preview_challenger_blizzard_1`, `teamwork_preview_challenger_blizzard_2`). #### 4. Lifecycle & Hygiene - Merged to `main` via `--ff-only` and pushed to `origin/main`. - Worktree `.worktrees/skill-blizzard` removed and branch `feat/skill-59-blizzard` deleted.
