Luck

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

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 in Fallout

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

Ways to increase Luck in 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 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.
 * If you have the Hubologist zeta scans, it will stop the decrease in luck from the Pariah Dog joining your party. Subsequently killing the pariah dog will then restore your Luck as if it had been decreased, resulting in a gain in Luck.

Fallout 3
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 your Critical Chance with all weapons.

Fallout: New Vegas
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 you win a casino bet through the influence of Luck, you receive a "You feel lucky" message. 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.

Ways to increase Luck

 * Completing the quests, The Apocalypse or The End, will allow you to raise a primary statistic by 1.
 * Temporary
