Stealth Girl

Stealth Girl is a companion perk in Fallout: New Vegas given by Lily Bowen if she is the Courier's companion. Lily can be obtained as a companion during the quest Guess Who I Saw Today.

Effects
With this perk, Stealth Boys last twice as long while also granting Sneak Attack Criticals an extra 10% damage. This perk makes a single Stealth Boy last 4 minutes (instead of 2).

Behind the scenes
This perk is named after the Stealth Girl, an item in the canceled Fallout: Brotherhood of Steel 2. The Stealth Girl acted as a Stealth Boy but lasted three times as long.
