Quick walkthrough

 * 1) Find a scorpion tail.

Detailed walkthrough
This unmarked quest is very straightforward. The player needs to first speak to Seth. He tells them that Jarvis, his brother, has been poisoned and that they can speak to Razlo for more information. Razlo is located in the building to the south. He will tell the player that he can create an antidote to the venom, but he first requires the venom sack from a radscorpion, which is inside their tail.

As soon as the player acquires a scorpion tail, they need to bring it back to Razlo, who will create an antidote, giving the player a free sample for personal use. The player can then open the curtain to the back of Razlo's hut where Jarvis is laying on a mattress. Using the antidote on him finishes the quest.


 * Regardless of the player's intelligence, they can still use antidote on Jarvis after obtaining it. However, if their Intelligence is less than 4, they will not be able to learn about this quest from Seth. They must visit Jarvis in the back of Razlo's hut, and try to talk to him. He will then give some floating dialogue telling the player about his ailment, and that they should see Seth if they want help removing the radscorpion threat.

Locations of scorpion tails
Scorpion tails will be in the inventory of all radscorpions upon death; however, they are quite heavy, weighing 20 pounds apiece.


 * If the player speaks to Aradesh and agrees to help his people by destroying the radscorpions, they will begin the quest Stop the Radscorpions. Part of the quest involves eliminating radscorpions inside their caves. Inside the caves are 9 radscorpions in total.
 * There are random encounters with radscorpions that can occur anywhere on the world map.
 * Radscorpions will spawn around the entrance to Vault 15 the first time the player visits.

Rewards

 * 400 XP.
