Strength

Strength is a Primary Statistic in the SPECIAL system.

Strength is a measure of your raw physical power. It affects how much you can carry, and determines the effectiveness of all melee attacks.

Fallout, Fallout 2, and Fallout Tactics
Modifies: Hit Points, Melee Damage, and Carry Weight

Strength is primarily relevant to two game mechanics: Carry Weight and satisfying the Minimum Strength requirements on weapons. You gain 25 lbs. of carry weight per point of Strength (unless you have the Small Frame trait, in which case it's 15). Also, if you meet the minimum strength requirements of your weapon you do not suffer accuracy penalties with that weapon.

Strength can be permanently increased by 6 points throughout both Fallout and Fallout 2.

Buffout and Jet can also temporarily modify Strength.

Fallout 3
Modifies: Melee Weapons skill, Carry Weight, melee damage bonus.

Note:* Does NOT affect unarmed damage in any way (see discussion page).

Fallout 1 & 2

 * Wearing T-51b Power Armor increases Strength by 3. Advanced Power Armor increases Strength by 4.
 * The Brotherhood of Steel can perform an operation to increase Strength by 1, assuming the player can afford it (Fallout 1) or has found the appropriate module chip (Fallout 2).
 * Buffout temporarily increases Strength by 2.
 * Several Perks increase Strength. Adrenaline Rush raises Strength by 1 when the player has less than 50% health. Gain (Statistic) Perk can be used to boost Strength by 1. Some Perks raise Strength when checking for modifiers. Heave Ho! raises Strength by 2 for purposes of throwing weapons. Weapon Handling boosts raises Strength by 3 for purposes of checking the minimum Strength needed to use a weapon.
 * The Bruiser Trait raises Strength by 2 but lowers the player's AP.

Fallout 3

 * The Strength Bobblehead can be found inside Lucas Simms' house in Megaton.
 * Strength can also be permanently increased by the Ant Might perk obtained as one of the reward from completing quest Those!.
 * Nerd Rage!, the perk, gives you 10 strength along with other bonuses (When health is below 20%).
 * The Intense Training perk will allow you to increase your Strength (or any other S.P.E.C.I.A.L. stat) once for each time that you take it.
 * The Enclave Power Armor gives +1 Strength; however, there may be a net loss in the amount you can carry because Power Armor weighs more than some other armors.
 * The Brotherhood Power Armor, Outcast Power Armor, and ordinary Power Armor gives +2 Strength.
 * Buffout also gives a short +2 boost.
 * Various forms of alcohol (in the Aid list) give a short +1 boost to strength. Taking additional alcohol or Buffout will not add more capacity for carrying, but alcohol and Buffout can be combined for +30 total. This can be enough to get some extra gear home when fast traveling and it might be possible to make two trips if done quickly.
 * Ant nectar gives you an additional +4 STR, so combined with Buffout and alcohol, you can pretty much carry 70 extra weight.

Fallout 3

 * Little Leaguer requires 4
 * Iron Fist requires 4
 * Strong Back requires 5
