Mysterious Stranger (Fallout 4)

Mysterious Stranger is a perk in Fallout 4.

Effects
When attacking an enemy in V.A.T.S., either from range or in melee, there is a chance for the Mysterious Stranger to appear and fire a single shot from his .44 revolver to instantly deal a massive amount of damage to a single target. The first rank grants a 10% chance, with the second and third rank each increasing the chance by 2%, for a total of 14%. Luck has no influence on the percentage.

Behind the scenes

 * The Mysterious Stranger perk was originally designed by Scott Bennie.
 * The Mysterious Stranger wields a revolver and wears a fedora and overcoat, like a protagonist of 1950s film noir.
 * There were several unfinished drafts of a book by Mark Twain titled "The Mysterious Stranger," in which the title character claims to be Satan's nephew, and which contain various references to the number 44.

Bugs

 * If the Mysterious Stranger is hit by an attack that makes him stagger before he has fired his weapon, he might not end up getting a chance to fire. This appears to happen more often in confined spaces. This does not adversely affect his future performance.
 * On occasions, the Mysterious Stranger will appear too close to the target, preventing him from taking a shot and killing the target. This is related to the game trying to place the Mysterious Stranger on the same level as his target. This does not adversely affect his future performance.
 * If one targets a Vertibird in V.A.T.S., the Mysterious Stranger may appear, but will not shoot at the Vertibird.
 * If the Mysterious Stranger appears while using V.A.T.S. on a ceiling turret, he will appear in the ceiling and will not damage the turret, This may also sometimes cause game crashes.
