# 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.

## 🤖 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-.
