Fate. Karma. An extremely high or low Luck will affect the character - somehow. Events and situations will be changed by how lucky (or unlucky) your character is.

Fallout in-game description

Luck is one of the seven primary statistics in the SPECIAL character system.

Fallout, Fallout 2, Fallout TacticsEdit

In Fallout, Luck primarily affects the chances with the virtual dice of the game: a high Luck increases the likelihood to succeed a roll, while the opposite is also true. Luck also affects the chance to score a critical hit on a target, with the standard being that the Critical Chance is equal to the subject's Luck (keep in mind, standard means without perks, traits, or aimed shots). It also determines the initial level of the Gambling skill.

Ways to increase Luck in FalloutEdit

  • Chuck in the Boneyard - Adytum can increase Luck permanently by one point via the mysteries of the Tarot.

Ways to increase Luck in Fallout 2Edit

  • The Hubologists can be visited to gain a Luck bonus. Only one bonus can be gained, though they have two bases, one in the NCR and one in San Francisco. The NCR bonus can either boost Luck by 2 or reduce it by one, and the San Francisco base can either boost Luck and Intelligence by 1, or reduce Luck by 1.
  • Taking the Gain Luck perk for an increase of 1 Luck.
  • With the Hubologist zeta scans, it will stop the decrease in Luck from the Pariah Dog's company. Subsequently killing the pariah dog will then restore Luck as if it had been decreased, resulting in a gain in Luck.

Fallout 3Edit

Modifies: All Skills and Critical Chance. Unlike other S.P.E.C.I.A.L. scores, Luck has no specific skills associated with it. Instead, every two points of Luck adds one point to all skills. Having a high Luck will also improve the Critical Chance with all weapons.

Ways to increase LuckEdit


Fallout: New VegasEdit

Luck functions in the same manner as Fallout 3. It raises the value of every skill (see chart at bottom of page) and affects Critical Chance. It also improves the odds of winning at any casino game; the higher the Luck, the more likely favorable outcomes on bets will be. If having won a casino bet through the influence of Luck, the "You feel lucky" message is displayed. A Luck of 6 will begin to influence Roulette and Slot machines, though rarely. A Luck of 7 is required to win with any regularity or to begin to influence Blackjack outcomes.

  • A Luck of 7, opens up a dialog option in the REPCONN headquarters to allow moving unharmed past the robots on the top floor.
  • The Courier can heal Caesar's brain tumor in the quest Et Tumor, Brute? with a Luck of 9.
  • If the Courier's Luck stat is the most extreme (highest or lowest), Doc Mitchell will either say he is surprised their bullets did not "turn right around and climb back into the gun." (for highest) or that they seem to be "the luckiest son-of-a-gun in New Vegas." (For lowest)
    • When Doc Mitchell refers to the bullets "climbing back into the gun" this is a nod to Fallout 1 and Fallout 2, referring to critical failures.
  • When playing at casinos, a Luck of at least 7 is required to get favorable odds. Blackjack is the most affected by Luck; at 10, it will produce fairly constant patterns in what cards are dealt to based on the current total. Slots will turn out losses on most spins, but at higher Luck will produce an occasional jackpot. Roulette, like Slots, will produce a loss on most spins and requires prudent betting to gain much benefit from Luck.

Fallout 4Edit

Luck is a measure of your general good fortune, and affects the recharge rates of critical hits.

Luck determines the recharge rate of the Critical Hit meter. It can indirectly improve how much caps and ammo one finds through one of two associated Luck perks (see below). It can also give the player a chance to not catch a disease from a molerat bite in Vault 81. Luck can affect the chances of quickly receiving a perfectly preserved pie from the Port-A-Diner (the lower your luck stat, the longer it can take).

Here is a table that shows how many hits one needs to refill the critical meter for different luck values. This does not include the effects of perks or legendary prefixes.
