The Outcast Collection Agent

You can trade some pieces of power armor, some energy weapons, sensor modules, and scrap metal to Protector Casdin. In return he will give you your choice of the following, in quantities according to the perceived value of the item:
 * 5.56mm ammunition
 * Frag grenades
 * Rad Away
 * Stimpaks

Once the Lone Wanderer has gained 50 "points" (see table below), they are told that they are considered friendly by the Outcasts. This allows for infiltration of Fort Independence without encountering the hostility of the residents (see Getting In).

Value Table
† Scrap Metal must be traded in groups of two; Alien Power Cells must be traded in groups of twelve.
