Teach the Scaven-pickers to make their own Rad-X

Teach the Scaven-pickers to make their own Rad-X was going to be a quest in Van Buren, the canceled Fallout 3 by Black Isle Studios. It is located at the Reservation.

Quick walkthrough
If the player has established communication with Klik, and has the Pharmacist perk, he can offer to teach Klik how to make her own version of Rad-X using ingredients from the Reservation region and a science kit. Of course the player would have to give a science kit to Klik. Another main ingredient is cockroach guts.

Character type completion breakdown

 * 1) Combat Boy, Diplomacy Boy, Stealth Boy - If the player learned even the basic version of the Scaven Pickers' language, has a science kit, cockroach guts, and has the Pharmacist perk (or Science skill >100), then he will be able to teach Klik how to make a version of Rad-X.
 * 2) Science Boy - More suited to Science Boy since most of the prerequisites are already part of his "class."
