🎨 Customization

Adding New Items

In generate.py, find ITEM_DATABASE:

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

Excluding Items

# Hilda-exclusive items
HILDA_EXCLUSIVES = {'CapeDeerHide', 'CapeTrollHide', ...}

# Pattern exclusions
EXCLUDED_PATTERNS = [r'^Bow_projectile', r'^fx_', ...]

Adjusting Prices

# Global adjustments
SELL_MULTIPLIER = 0.30      # Change sell ratio
CRAFTING_MARKUP = 1.15      # Change crafting fee

# Biome multipliers in Biome enum
MEADOWS = ("Meadows", 1.5, "", 1)  # (name, mult, boss_key, order)

# Category multipliers
CATEGORY_MULTIPLIERS = {'weapon_2h': 1.3, 'weapon_1h': 1.0, ...}

# Rarity overrides for specific items
RARITY_OVERRIDES = {'Chain': 1.8, 'Eitr': 1.8, ...}
