Luck

Luck is one of the seven Primary Statistics in the SPECIAL character system. It represents 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, Fallout 2, Fallout Tactics
In Fallout, Luck primarily affects your chances with the virtual dice of the game, a high luck means you're more likely to succeed a roll, while the opposite is also true. Luck also affects the chance to score a critical hit on an enemy, with the standard being that your Critical Chance is equal to your luck (keep in mind, standard means without perks, traits, or aimed shots). It also determines the initial level of your Gambling skill.

Ways to increase Luck

 * Fallout - Chuck in the Boneyard - Adytum can increase your Luck permanently by one point via the mysteries of the Tarot.
 * Fallout 2 - The Hubologists can be visited to gain a luck bonus. Only one bonus can be gained, though they have two bases, one in NCR and one in San Francisco. The NCR bonus can either boost Luck by 2 or reduce it by one, and the Frisco one can either boost Luck and Intelligence by 1, or reduce them by that amount.

Fallout 3
Unlike other S.P.E.C.I.A.L. scores, Luck has no specific skills associated with it. Instead, every two points of Luck add one point to all skills. Having a high Luck will also improve your critical chance with all weapons.

Ways to increase Luck

 * The Luck Bobblehead, in the cellar of Arlington House, permanently increases Luck by 1.
 * The Intense Training perk will allow you to increase your Luck (or any other S.P.E.C.I.A.L. stat) once for each time that you take it.
 * The Lucky 8 Ball also increases Luck by 1 as long as it's carried. The Lucky 8 Ball can only be obtained from save Timebomb in Big Town, if you perform surgery on him (Medicine 40 required), and the town after rescuing Red. After you help save the town, talk to Timebomb and he will reward you with the Lucky 8 Ball.
 * Certain pieces of apparel, such as the lucky shades or Ranger battle armor, can increase Luck while worn.
 * The Broken Steel add-on perk Almost Perfect raises all S.P.E.C.I.A.L. stats to 9 if it isn't already 9.

Fallout: New Vegas

 * A higher Luck stat will improve your chances of winning at any of the Casino games. Occasionally, a "You feel lucky" message will appear and you will win your current Roulette spin, Blackjack hand, or Slot machine spin.
