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

## Fallout, Fallout 2 and Fallout TacticsEdit

The chance to cause a critical hit in combat is increased by this amount.

— Fallout In-game description

An Aimed Shot has a higher chance to score a critical hit than an unaimed shot. In Fallout Tactics, the Science skill also has an effect on critical chance against robotic enemies.

$\text{Initial level}=\text{Luck}\times1\%$
• 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 3Edit

### Base ChanceEdit

Luck is the main base factor that determines the chances of a critical strike on an opponent.

$\text{Initial level}=\text{Luck}\times1\%$

Example: A starting Luck of 5.

$5~(\text{Luck}) \times 1\%=5\%~(\text{Base chance})$

Notes:

• Maximum initial base is capped at 10%.
• Ninja perk can increase this limit by another +15% for Melee and Unarmed weapons.
• Finesse perk can increase this limit by another +5%.
• Survival Guru perk can increase this limit by another +3%.
• Strikes dealt in V.A.T.S have additional +15% critical chance added.
• Some weapons have 0% chance of a critical strike (see Critical Multiplier for detail of effects).

pc You can also check your critical chance with the console command player.getav critchance.

### Critical MultiplierEdit

All weapons have a critical multiplier that modifies the player character's base critical hit chance. This may improve or hinder the ability to score a critical hit depending on the weapon's Critical multiplier.

$\text{Base chance}\times\text{Critical multiplier}$

Example: A starting Luck of 5 and using a sniper rifle, which has a x5 Critical Multiplier.

$5\%~(\text{Base chance})\times5~(\text{Critical multiplier})=25\%~(\text{Critical chance})$

Notes

• The critical multiplier for fully-automatic weapons is much lower than for single-shot weapons.
• There are a few weapons that have a x0 multiplier, making it impossible to score a critical hit.
• For a detailed list of weapon critical multipliers, see here.

### Weapon ConditionEdit

The final critical chance is also modified by weapon condition.[1]

$\mbox{Critical chance} \times \mbox{Condition}$

For example, a character with 5 Luck and using a sniper rifle in 50% condition would have,

$25\%~(\text{Critical chance})\times\frac{50}{100}~(\text{Condition})=12.5\%~\text{Critical chance}$

## Fallout: New VegasEdit

The formulas for critical chance seem unchanged from Fallout 3. You receive 1% of critical chance for each point placed into Luck. During character creation, you can add an additional 3% for all weapons by choosing the Built to Destroy trait.

Attributes, perks and traits that increase critical chance include
¹ The critical chance added by these perks is a flat bonus and is not affected by your weapon's critical multiplier.
² Ninja multiplies your total critical chance after all modifiers by 1.15; thus it adds 15% of your normal critical chance, not a flat 15% boost.
Items that increase critical chance
¹ The critical chance added by V.A.T.S. is a flat bonus and is not affected by your weapon's critical multiplier.

Currently, the highest possible critical chance that will be affected by your multiplier is 38% (10 Luck, Finesse, Built to Destroy, 1st Recon Beret, Elite riot gear/Ulysses' Duster, True Police Stories with Comprehension). As mentioned above, Light Touch, Laser Commander, Set Lasers for Fun, Ninja, and V.A.T.S. can further increase your chance.

## Fallout: Brotherhood of SteelEdit

In Fallout: Brotherhood of Steel, a critical hit allows to exceed the maximum limit of damage for a weapon.

Some weapons are very powerful with a high critical chance, such as the double-barrel shotgun or The Slugger and also the weapons in bursts.

An energy weapon with the skill Energy Charge or a Melee weapon with the skill Special Attack can be extremely powerful if the charged attack is a critical hit.

The chance to cause a critical hit in combat is increased by

Initial Level: Each character starts with a 1% critical chance.

• The Butcher skill (only Cain) increases the critical chance by 5% only for blades for each ranks until a total of 25%.
• The Desert Soldier skill (only female character) increases the critical chance by 5% only for conventional weapons (weapon that uses 9mm) for each ranks until a total of 25%.
• The Future Woman skill (only female character) increases the critical chance by 5% only for energy weapons for each ranks until a total of 25%.
• The Heavy Hitter skill (only human male character) increases the critical chance by 5% only for Blunt weapon (Gloves, Clubs and Hammers) for each ranks until a total of 25%.
• The Pyromaniac skill (only Cain) increases the critical chance by 5% when using a fire-based weapon (like the frag grenade, flamer, etc.) for each ranks until a total of 25%.
• The Slayer skill increases the critical chance by 5% for each ranks until a total of 25%.
• The Wastelander skill (only human male character) increases the critical chance by 10% only when using home-made weapons for each ranks until a total of 50%.

The type of weapon with a maximum critical chance with the skill required is the home-made weapons with a total of 75%.
