Critical Chance is a derived statistic in Fallout, Fallout 2, Fallout 3, Fallout Tactics and Fallout: Brotherhood of Steel.

Fallout, Fallout 2 and Fallout Tactics
The chance to cause a critical hit in combat is increased by this amount.

Initial Level: Starting critical chance is equal to your Luck. Average characters will have a 5% critical chance.


 * The Finesse trait increases the critical chance by 10%.
 * The More Criticals perk increases the critical chance by 5% per rank.
 * The Sniper perk increases the critical chance to 10*Luck for ranged weapons.
 * The Slayer perk increases the critical chance to 100% for melee weapons.

Fallout 3
Permanently increasing Critical Chance
 * Each point of Luck gives +1% Critical Chance.
 * The Ninja perk gives +15% Critical Chance, but only with Melee or Unarmed weapons.
 * The Finesse perk gives +5% Critical Chance.
 * The Survival Expert perk gives up to +3% Critical Chance.

The maximum amount of base Critical Chance you can gain from perks and Luck in Fallout 3 is +18% for Ranged Weapons and +33% for Melee and Unarmed weapons.

It should also be noted that strikes dealt in VATS have a +15% critical chance bonus. Keep in mind that weapons like the Ripper or Kneecapper have a critical multiplier of 0% and therefore cannot score critical strikes, including sneak criticals.
