You have a fear of enclosed spaces (probably because of the mutants that live there). You gain +1 to SPECIAL attributes when outside, but suffer -1 when indoors.”— In-game description, Fallout: New Vegas
When outside you gain +1 to all SPECIAL stats but when indoors, you suffer -1 to all SPECIAL stats.
- Despite the description, there are some "outside" places where you will suffer the -1 all SPECIAL stats penalty. This includes places such as The Strip and Freeside, as they are different cells than the wasteland.
- The REPCONN test site launch platform apparently counts as "outside". It is unknown if this is intentional.
- This trait could make lockpicking or hacking while in an interior difficult. However this difficulty can be offset with various chems or magazines.
