Collect Radscorpion Tails is a quest in Fallout: Brotherhood of Steel.
This quest is given by Armpit in Carbon Bar after the Initiate has killed the raiders during the quest Kill Drunken Raiders. The goal is to collect the radscorpion tail when you kill any radscorpions. Radscorpion tails can be collected during the Kill Warehouse Radscorpions quest and must be turned in before going into Carbon Crater to receive the reward. After the warehouse radscorpions will not drop tails and Armpit will not accept them after the Initiate returns from the crater. The quest ends when Armpit dies upon the Initiate's return from the crater during the attack by raiders and gives radscorpion liquor recipe at the end.
