Scorpion tail

A scorpion tail is a miscellaneous item in Fallout, Fallout 2 and Fallout: Brotherhood of Steel.

Background
The tail can be taken from dead radscorpions and sold almost anywhere, and is prized for the poison sac it contains, which is used to make a poison antitode.

Characteristics
They are the tails of radscorpions, while they are prized for the poison glands they have been cut at the base where the tail meets the body. The tail is comprised of the segmented sections of the tail ending in the stinger, they vary in size depending on the radscorpion, and vary slightly in appearance across the different games, the Tactics version even shows a small amount of poison on the stinger. The cleanness of the severing point varies slightly, although this does not affect its value or potential uses.

Fallout
Usually obtained from recently-deceased radscorpions, though a few can be found elsewhere.

Fallout 2
Radscorpions can be fought and looted of their tails in the Temple of Trials, Myron can use the tails to make the antidote. One can be used to poison the Wright's still. Over time, the citizens of New Reno will start dying. This doesn't effect any family members, but it will kill Father Tully. The intelligent radscorpion's tail can be removed while still alive without consequence as long as the Chosen One succeeds.

Fallout
Razlo in Shady Sands uses them to make the antidote.

Fallout 2
Myron in the Stables can use the tails to make antidote.

Fallout: Brotherhood of Steel
