Fur rarity

What is it?

Fur rarity describes how difficult it is to obtain a specific type of animal fur. The higher the rarity, the more exclusive and harder to find the fur is. The rarity is automatically calculated using a combination of certain values and conditions.

Values used in the calculation

  • Basic percentage โ€“ How often the fur appears overall.
  • Gender availability โ€“ Whether the fur is available to both males and females, or only one gender.
  • Weighted rarity โ€“ A mathematical formula that emphasizes extreme rarity by squaring the percentage chance and scaling it - percentยฒ / 20. This highlights small differences more strongly, especially for rare furs.
