# 디아블로 2(Diablo II)

## 매 한 줄
> **"매 ARPG 의 archetype — 매 random loot + skill tree + hardcore + ladder."**. 매 2000 Blizzard North 의 release, 매 isometric 2D sprite 의 era, 매 2021 의 Resurrected 의 modernized 3D rendering, 매 modern ARPG (Path of Exile, Last Epoch, Diablo IV) 의 design DNA.

## 매 핵심

### 매 design pillars
- Random loot tables: magic / rare / set / unique items.
- Skill trees: 매 class 마다 의 30 skills 의 3 tabs.
- Difficulty tiers: Normal → Nightmare → Hell.
- Ladder seasons: 매 fresh economy reset.
- Hardcore mode: 매 death 의 permanent.

### 매 architecture
- Client-server (Battle.net): 매 anti-cheat 의 server-authoritative.
- Tile-based map generation: 매 procedural dungeon.
- Sprite system: 매 8 directions × frames × layers.
- MPQ archive: 매 asset packing format.

### 매 응용
1. Loot system 의 modern ARPG influence.
2. Skill tree 의 RPG genre 의 standard.
3. Online economy 의 trading mechanics.
4. Modding scene (Median XL, Path of Diablo).

## 💻 패턴

### Pattern 1 — Loot table weighting (pseudocode → C)
```c
typedef struct { ItemType type; int weight; } LootEntry;
LootEntry table[] = {
  {NORMAL,   60}, {MAGIC, 25}, {RARE, 10},
  {SET,       3}, {UNIQUE, 2}
};
int roll = rand() % 100;
int acc = 0;
for (int i = 0; i < 5; i++) {
  acc += table[i].weight;
  if (roll < acc) return table[i].type;
}
```

### Pattern 2 — Magic find (MF) calculation
```c
// effective_chance = base_chance * (1 + MF/100)
// but with diminishing returns formula
float effective_mf(float mf, float factor) {
    return (mf * factor) / (mf + factor);
}
// Unique factor = 250, Set = 500, Rare = 600
```

### Pattern 3 — Skill synergy (D2 LoD)
```c
// Damage = base * (1 + 0.10 * synergy_skill_level)
int fireball_damage(int level, int fire_bolt_lvl, int meteor_lvl) {
    int base = 18 + level * 4;
    float synergy = 1.0f + 0.10f * (fire_bolt_lvl + meteor_lvl);
    return (int)(base * synergy);
}
```

### Pattern 4 — Item affix prefix/suffix
```c
struct Item {
    BaseType base;
    Affix prefix[3];   // e.g., "of Speed"
    Affix suffix[3];   // e.g., "Cruel"
    int sockets;
};
// Rare = 4-6 affixes, Magic = 1-2
```

### Pattern 5 — Resurrected toggle (legacy ↔ modern render)
```cpp
// D2R retains original game logic, swaps render layer
if (settings.legacyRender) {
    Render2DSprites(scene);  // original DirectDraw path
} else {
    Render3DRemastered(scene); // Vulkan/D3D12, PBR materials
}
```

### Pattern 6 — Open Battle.net character (insecure, historical)
```
// "Open" chars stored client-side → trivial to dupe/edit.
// "Closed/Realm" chars stored server-side → authoritative.
// Lesson: server-authoritative state is non-negotiable for online RPGs.
```

## 매 결정 기준
| 상황 | Approach |
|---|---|
| 매 modern ARPG design | D2 의 loot + skill tree 의 baseline |
| 매 anti-cheat | Server-authoritative state |
| 매 retention | Ladder / season reset |
| 매 monetization 2026 | Cosmetics-only (D2R) vs MTX (D4) |

**기본값**: 매 server-authoritative + 매 seasonal ladder.

- 응용: [[Skill-Tree-Design]]
- Adjacent: [[Procedural-Generation]]

## 🤖 LLM 활용
**언제**: 매 ARPG mechanic 의 design 시, 매 loot table 의 balance 분석, 매 skill synergy 의 formula 설계.
**언제 X**: 매 specific D2 의 internal undocumented bug 의 정확한 reproduction (data 부족).

## ❌ 안티패턴
- **Client-authoritative state**: D2 Open Battle.net 의 mass duping 의 lesson.
- **Power creep**: 매 patch 마다 의 damage inflation 의 trivialize content.
- **No drop rate transparency**: 매 modern player 의 expectation 위반.
- **Pay-to-win**: 매 D2 의 cosmetic-only 의 reputation 의 maintain.

## 🧪 검증 / 중복
- Verified (Blizzard official patch notes, D2 LoD wiki, Resurrected dev interviews).
- 신뢰도 A-.
