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.

 * One can be found in the same location, on one of the tables in a room with the sign "Food".
 * On the way up the path to REPCONN Test Site from Novac you can find one in an ash pile on the floor.
 * There is a random chance to spawn in nightkin corpses. More likely if it hasn't used the stealth boy yet. In that case, high Perception, Spotter, or Enhanced Sensors always helps.
