# 🗡️ Elden Ring QA Dataset

A domain-specific question-answering dataset for Elden Ring, covering weapons, bosses, armors, spells, NPCs, locations, creatures, skills, and ashes of war — including cross-entity boss vulnerability analysis and per-build weapon recommendations.

## Dataset Description

- **Created by:** ArenaRune
- **Language:** English
- **License:** CC-BY-NC-4.0 (dataset construction; game content belongs to FromSoftware/Bandai Namco)
- **Source data:** Kaggle CSVs + GitHub lore archives (see Sources below)

## Uses

### Intended Uses

- Fine-tuning language models for Elden Ring domain-specific QA
- Training instruction-following models on structured game knowledge
- Retrieval-augmented generation (RAG) systems for game wikis/chatbots
- Research on domain adaptation and factual grounding in LLMs

### Out-of-Scope Uses

- Commercial game guide products (game content belongs to FromSoftware)
- Factual reference without verification (some generated answers may contain approximations)

## Dataset Structure

### Format

JSONL — one JSON object per line.

### Fields

| Field | Type | Description |
|-------|------|-------------|
| `instruction` | string | Natural language question about Elden Ring |
| `input` | string | Always empty |
| `output` | string | 1-2 sentence factual answer |
| `metadata.entity_type` | string | Entity category (see below) |
| `metadata.question_type` | string | Question category (see below) |
| `metadata.entity_name` | string | Entity the question is about |

### Example

```json
{
  "instruction": "What weapons are good against Mohg, Lord of Blood?",
  "input": "",
  "output": "Effective weapons against Mohg include: Varre's Bouquet (arcane build - Applies Hemorrhage, boss resistance: 290 / 332 / 430 / 720); Rivers of Blood (dexterity build - Applies Hemorrhage).",
  "metadata": {
    "entity_type": "boss",
    "question_type": "weapon_recommendation",
    "entity_name": "Mohg, Lord of Blood"
  }
}
```

### Entity Types

| Entity Type | Description |
|-------------|-------------|
| `weapon` | Swords, axes, staves, bows, shields, etc. |
| `boss` | Major and minor boss encounters |
| `armor` | Helms, chest armor, gauntlets, leg armor |
| `sorcery` | Intelligence-based spells |
| `incantation` | Faith/Arcane-based spells |
| `npc` | Non-player characters |
| `location` | Dungeons, regions, landmarks |
| `creature` | Regular enemies |
| `skill` | Weapon arts and abilities |
| `ash_of_war` | Equippable skill items |

### Question Types

**Weapons:** lore, category, requirements, scaling, passive, skill, weight, base_damage

**Bosses:** lore, location, hp, weakness, weapon_recommendation, weapon_rec_{build}, status_check, inflicts, parry, boss_damage, drops

**Spells:** lore, effect, requirements, location, school

**NPCs:** lore, location, role

**Locations:** lore, region, bosses, npcs, items, creatures

**Armors:** lore, stats, acquisition, special

**Creatures:** lore, location, drops

**Ashes of War / Skills:** lore, skill, effect, equipment

### Question Phrasing

Each question type includes 2-4 randomized phrasings mixing formal and casual styles:

- `"What are the stat requirements for Rivers of Blood?"`
- `"What stats do I need for Rivers of Blood?"`
- `"I'm running a strength build, what should I use against Malenia?"`
- `"Does bleed work on Mohg?"`
- `"How do I beat Radahn?"`

## Loading the Dataset

```python
from datasets import load_dataset

dataset = load_dataset("your-username/elden-ring-qa-dataset")

# Access examples
for ex in dataset["train"]:
    print(ex["instruction"])
    print(ex["output"])
    print(ex["metadata"]["entity_type"])
```

### Stratified Splitting

The metadata enables stratified train/val/test splitting to ensure all `(entity_type, question_type)` combinations appear in every split:

```python
from collections import defaultdict
import random

def stratified_split(dataset, train_r=0.8, val_r=0.1, test_r=0.1):
    groups = defaultdict(list)
    for i, ex in enumerate(dataset):
        key = (ex["metadata"]["entity_type"], ex["metadata"]["question_type"])
        groups[key].append(i)
    
    train_idx, val_idx, test_idx = [], [], []
    for key, indices in groups.items():
        random.shuffle(indices)
        n = len(indices)
        n_train, n_val = max(1, int(n * train_r)), max(1, int(n * val_r))
        if n >= 3:
            train_idx.extend(indices[:n_train])
            val_idx.extend(indices[n_train:n_train + n_val])
            test_idx.extend(indices[n_train + n_val:])
        elif n == 2:
            train_idx.append(indices[0])
            val_idx.append(indices[1])
        else:
            train_idx.append(indices[0])
    return train_idx, val_idx, test_idx
```

## Construction Pipeline

```
extract_lore.py   →  master_lore.json        (HTML lore extraction)
                           ↓
fuse_data.py       →  elden_ring_enriched.json (Data fusion + cross-referencing)
                           ↓
generate_qa.py     →  elden_ring_final_train.jsonl (QA pair generation)
```

### Key Pipeline Features

- **Fuzzy name matching** across sources using `difflib` (0.75 cutoff)
- **Nested data parsing** of string-encoded dicts/lists via `ast.literal_eval`
- **Boss vulnerability analysis:** Determines physical weakness (lowest damage negation), ranks status vulnerabilities by base resistance, and cross-references weapon index for per-build recommendations
- **Weapon indexing:** Groups weapons by damage type, status effect, category, and primary scaling stat
- **Location cross-referencing:** Reverse lookups from locations to bosses, NPCs, creatures

## Unique Features

### Boss Vulnerability → Weapon Recommendations

Each boss entry includes programmatically generated weapon recommendations distributed across 5 build archetypes:

- **Strength** — weapons with high Str scaling matching boss weakness
- **Dexterity** — weapons with high Dex scaling matching boss weakness
- **Intelligence** — weapons with high Int scaling matching boss weakness
- **Faith** — weapons with high Fai scaling matching boss weakness
- **Arcane** — weapons with high Arc scaling matching boss weakness

Recommendations are scored by:
1. Status effect match weighted by boss resistance (lower resistance = higher score)
2. Physical damage type match weighted by boss negation difference
3. Weapons appearing in both status AND physical match score highest

### Status Vulnerability Ranking

Boss status resistances like `"290 / 332 / 430 / 720"` are parsed and ranked. Lower base resistance = more effective. For example, Mohg has Hemorrhage resistance of 290 vs Scarlet Rot at 653, so Bleed weapons are prioritized in recommendations.

## Limitations

1. **Lore coverage:** ~40% of entities have matched lore from HTML archives; rest use CSV descriptions
2. **DLC weapon scaling:** `elden_ring_weapon.csv` covers base game only; DLC weapons may lack scaling data
3. **Elemental weakness:** Boss stats CSV does not include elemental damage negation — only physical types
4. **Resistance parsing:** Some bosses have `"????"` resistance values, treated as immune
5. **Recommendation scope:** Based on damage type + status + scaling only, not moveset or player skill
