Stealth Boy (Fallout: New Vegas)

The Stealth Boy is a consumable item in Fallout: New Vegas.

Characteristics
The RobCo Stealth Boy 3001 is a personal stealth device worn on one's wrist. It generates a modulating field that transmits the reflected light from one side of an object to the other, making a person much harder to notice (but not completely invisible).

Side effects
While they seem to not have any adverse effects on humans, Stealth Boys increase the risk of schizophrenia in super mutants. This is especially dramatic in the case of the nightkin, who, as permanent Stealth Boy users, nearly always show one or several symptoms of paranoid schizophrenia, such as paranoia, hallucinations, and/or delusion. Doctor Henry in Jacobstown is researching these side effects, hoping to develop a means to help the nightkin.

Locations

 * One can be found in the Goodsprings schoolhouse, in an easy lock safe.
 * Another is carried by Joe Cobb.
 * Several can be found in the REPCONN Test Site.
 * One can be found in the REPCONN Test Site, right next to the dead nightkin as you walk in the front door.
 * One can be found in the basement, on one of the tables in the room with the sign reading "Food".
 * On the way up the path to REPCONN Test Site from Novac you can find one in the disintegrated remains of a nightkin.
 * Veteran Atticus in Caesar's Legion Safehouse will give two to the player for free every time he is at the safehouse making him the only indefinite supply of Stealth Boys in the Mojave.
 * One can be found in the middle of Jack Rabbit Springs beside a skeleton, along with a Weapon repair kit
 * Approaching the cattle pen in Brooks Tumbleweed Ranch reveals a nightkin who offers to sell you a 'wind brahmin' (a tumbleweed) for all your caps. He will then give you a Stealth Boy as a gift. Killing the nightkin afterwards or pickpocketing him produces another Stealth Boy as well as all your caps back.
 * One can be found in the REPCONN Headquarters behind an average locked door in a container on the top floor.
