Miss Fortune

Miss Fortune is a perk in Fallout: New Vegas.

Effect
With this perk, Miss Fortune will appear 10% of the time in V.A.T.S. to attack enemies. To trigger an appearance, the player character must complete a series of attacks in V.A.T.S. without killing their opponent.

Unlike the Mysterious Stranger, Miss Fortune's attacks deal low damage to an area, aiming to cripple and knockdown enemies rather than kill them outright.

Miss Fortune's gun creates a "fortune" percentage for the target.

If their fortune is under 35:
 * Knock-down for 10 seconds.
 * Any of the following will detonate if they are in the inventory and are at least 1 game unit further away from the player character than the max splash damage range, with an appropriate explosion:
 * Incendiary grenade; creates a 40mm incendiary explosion.
 * Frag grenade, dynamite, or bottlecap mine; creates a 40mm explosion.
 * Plasma grenades or plasma mines; creates a plasma grenade explosion.
 * Pulse grenades or pulse mines; creates a pulse grenade explosion.

If their fortune is between 35 and 65:
 * Any of the grenades explosives before will detonate, as well as:
 * Flamer, incinerator, or heavy incinerator; creates a 40mm incendiary explosion.
 * Grenade launcher, grenade rifle, grenade machinegun, missile launcher, or Securitron missile launcher; creates a 40mm explosion.
 * Recharger pistol, recharger rifle, plasma pistol, plasma rifle, multiplas rifle, plasma caster, or Plasma Defender; creates a plasma grenade explosion.
 * Pulse gun; creates both a plasma and a pulse grenade explosion.
 * If any of these detonate, the weapon will be broken and the NPC's right arm be crippled. If none of the weapons are present, a "cripples" percentage is set instead:
 * Below 10 cripples the head.
 * 10 - 25 cripples the left arm.
 * 25 - 40 cripples the right arm.
 * 40 - 55 cripples the left leg.
 * 55 - 70 cripples the right leg.
 * Above 70 cripples the torso.
 * If all limbs are crippled beforehand, the target is paralyzed.

If their fortune is above 65, only the limb crippling is applied. Remember, this is all determined per shot, and Miss Fortune will more than likely empty her revolver for all 6 shots in a V.A.T.S. attack.

Behind the scenes
The name Miss Fortune is a play on the word "misfortune" and the phrase "Lady Luck".

Bugs

 * Sometimes when she appears, your AP Sequence will continue even after delivering your attack, leaving you unable to defend yourself.
 * Sometimes when she appears, she isn't visible, and it makes her seem to stand in the way of the enemy, making you shoot Miss Fortune instead.
 * Rarely in V.A.T.S. she will appear and your console will freeze.
 * Rarely in V.A.T.S., it is possible for The Mysterious Stranger and Miss Fortune to appear at the same time.
