Output	`buy.json` (579 items) + `sell.json` (593 items)

🎨 Customization

Adding Items

'ItemPrefab': (Biome.TIER, base_price, stack_size, sell_only),

Excluding Items

HILDA_EXCLUSIVES = {'ArmorDress1', 'ArmorTunic1'}
EXCLUDED_PATTERNS = [r'^Bow_projectile', r'^fx_']

Adjusting Prices

SELL_MULTIPLIER = 0.30
CRAFTING_MARKUP = 1.15
CATEGORY_MULTIPLIERS = {'weapon_2h': 1.3}
RARITY_OVERRIDES = {'Chain': 1.8}

🔍 Troubleshooting

Issue	Solutions
Items not appearing	Check `item_prefab` name · Verify boss defeated · Validate JSON syntax
Wrong prices	Re-run `generate.py` · Check `ITEM_DATABASE` · Verify ingredients
Script errors	Install Python 3.x · Check internet connection · Try custom path
