A firefox tail is a tail severed from a dead firefox. When your hero defeats a firefox he will sometimes decide to sever the tail and keep it. Worn by the upper class of Godville this tail can be sold to any trader for a mid to high price. Some people say that it has magical properties that either bless or curse the heroine depending on the color of the fur. Due to the fact that firefoxes are often tamed as pets, there aren't many of these tails floating around. If you get one, you might as well head to Tradeburg where you can get the highest price for this fur.
