Carry Weight (Fallout 76)

{for|a cross-game overview|Carry Weight}} {

Carry Weight is a statistic

Overview
Movement speed is unaffected by carry weight unless overencumbered; one can run, fast travel, and jump. Fallout 76 differs in that moving while overencumbered drains action points like sprinting. After all points are used, one's movement will be greatly reduced.

Game settings for carrying capacity:
 * fAVDCarryWeightBase = 150.0
 * fAVDCarryWeightMult = 5.0
 * $$\text{Carrying capacity}=\text{fAVDCarryWeightBase}+(\text{Strength}*\text{fAVDCarryWeightMult})$$

Carry weight is capped to an absolute limit of 1,500 pounds over the player character's current maximum carry weight, though nothing prevents a player character from exceeding this limit. However, there are penalties such as the inability to drop or trade items until carry weight drops below this threshold; dropped items will be destroyed until then. Weight reduction perks can be used to help circumvent this limitation.

Backpacks
With the introduction of Wild Appalachia, player characters who complete The Order of the Tadpole are rewarded with, and become able to craft, a backpack that provides +10/+20/+30/+40/+50/+60 carry weight, at levels 1/10/20/30/40/50, respectively.

The High Capacity mod for the backpack provides an extra +10/+20/+30/+40/+50/+60, totaling to +20/+40/+60/+80/+100/+120 carry weight, at the expense of -10/-20/-30/-40/-50/-60 points of energy and radiation resistance. The other modifications all lower the backpack's carry weight down to +5/+10/+15/+20/+25/+30, while giving other benefits.

Small backpacks
Another, smaller backpack increases carry weight by half the amount of a normal backpack. The plan for the small backpack can be found in the Overseer's cache in Morgantown Airport. After learning, the small backpack can be crafted at an armor workbench. While it increases carry weight less than the normal backpack, it is nonetheless useful to increase one's carry weight without the need to complete a lengthy questline.

It provides +5/+10/+15/+20/+25/+30 carry weight, at levels 1/10/20/30/40/50, respectively. This backpack can also be modded with High Capacity, at halved capacities, providing an extra +5/+10/+15/+20/+25/+30, totaling to +10/+20/+30/+40/+50/+60 carry weight, at the same expense of energy and radiation resistance points as the normal backpack.

Weight-related perks
Several weight perk cards assist in lightening the burden of weight, with higher tier cards reducing more:
 * Strength perks:
 * Bandolier - Ballistic weapon ammo weighs 45%/90% less.
 * Bear Arms - Heavy Guns weigh 30%/60%/90% less.
 * Martial Artist - Your melee weapons weigh 20%/40%/60% less, and you can swing them 10%/20%/30% faster.
 * Ordnance Express - Explosives weigh 30%/60%/90% less.
 * Pack Rat - The weight of all junk items is reduced by 25%/50%/75%.
 * Scattershot - Shotguns now weigh 30%/60%/90% less and you reload them 10%/20%/30% faster.
 * Strong Back - Gain +10/+20/+30/+40 to carry weight.
 * Sturdy Frame - Armor weighs 25%/50% less than normal.
 * Traveling Pharmacy - Weights of all Chems (including Stimpaks) are reduced by 30%/60%/90%.
 * Intelligence perks:
 * Batteries Included - Energy weapon ammo weighs 30%/60%/90% less.
 * Portable Power - All Power Armor parts and chassis weights are reduced by 25%/50%/75%.
 * Agility perks:
 * Packin' Light - Your pistols weigh 25%/50%/75% less.
 * Thru-hiker - Food and drink weights are reduced by 30%/60%/90%.

Strength-related perks
Not to be confused with perks cards in the Strength category, there are perk cards that affect one's total Strength, which in turn affect their carry weight.
 * Endurance perks:
 * Radicool - The greater your rads, the greater your strength! (+5 Max)
 * Solar Powered - Gain +1/+2/+3 to STR and END between the hours of 6:00 a.m. and 6:00 p.m.
 * Legendary perks:
 * Legendary Strength - +1/+2/+3/+5 STR and +1/+2/+3/+5 STR Perk Points. Perk Points cap at 15.
 * Despite not gaining Strength perk points for equipping this card while having allocated 14 SPECIAL points into Strength, one will still receive Strength points and, therefore, be granted with more carry weight.

Consumables
There are a plethora of consumable items a player character may use to modify their carry weight temporarily, with additional effects. Some of these directly change the player character's carry weight, while many of them modify carry weight indirectly by increasing or decreasing the Strength statistic, which in turn changes carry weight according to the formula above.

Mutations
Five mutations affect carry weight:
 * Marsupial adds 20 to the player character's carry weight, while additionally providing improved jump height. Its negative effect reduces the player character's Intelligence by 4.
 * Bird Bones reduces the player character's Strength by 4, which reduces not only carry weight but melee damage as well. Its positive effect improves the player character's Agility by 4 and slows their fall.
 * Eagle Eyes reduces the player character's Strength by 4. Its positive effect improves the player character's Perception by 4 and increases critical damage by 25%.
 * Egg Head reduces the player character's Strength and Endurance by 3. Its positive effect improves the player character's Intelligence by 6.
 * Herd Mentality increases all SPECIAL stats by 2 when the player character is on a team but reduces those stats by 2 when they are solo.

The Strange in Numbers perk card strengthens mutation benefits by 25% if other members on one's team are mutated as well. It boosts Marsupial's carry weight bonus to 25, as well as further improving its jump height. It will also increase Herd Mentality's SPECIAL stat gain to +3.

Mutations regarding consumption
If affected by the Carnivore mutation, consuming any of the listed meat items above will double the benefits, along with doubled healing and hunger restoration. The nullification of disease chance from consuming meat does nothing here as the meat items listed here are cooked; they do not have chances to inflict diseases.

Additionally, if equipping the Strange in Numbers perk card, the benefits, healing, and hunger restoration are further increased by half; from a bonus multiplier of 2.0 to 2.5. For example, eating smoked mirelurk fillets while being affected by Carnivore and equipping Strange in Numbers will grant the consumer a carry weight bonus of 75, a healing of 625 HP, and a filling hunger restoration of 62.5%.

Armor mods
There are four armor modifications that allow the wearer to carry more items and/or reduce the specific item's weight:
 * Pocketed - An armor mod that increases carry weight by 10, for the torso, and 5, for the limbs. Increases weight of armor by 10%.
 * Deep Pocketed - An armor mod that increases carry weight by 20, for the torso, and 10, for the limbs. Increases weight of armor by 15%.
 * Lighter Build - An armor mod that reduces the weight of armor by 40% and increases AP by 2.
 * Ultra-light Build - An armor mod that reduces the weight of armor by 80% and increases AP by 5.

Underarmor mods
There exists four tiers of underarmor modifications that apply SPECIAL stat and minor resistance bonuses, each tier providing more the higher it is. Various amounts of Strength is granted from five of the seven types of underarmor when modded.

Legendary effects
Weapons and armor can have legendary effects and some effects modify the weight of the starred item itself and/or other items the player character is carrying.


 * Weapons may have a third star effect and armor a second star effect of providing +1 Strength.
 * Weapons may have a third star effect "Lightweight", which reduces the base weapon weight by 90%. This doesn't provide any weight reduction to any mods on this weapon and can be further reduced, with Bear Arms, Martial Artist, Scattershot, or Packin' Light.
 * Armor with the first star effect "Weightless" reduce its own weight by 90% and also can be further reduced, with Sturdy Frame. In addition, Weightless armor does not count against the Chameleon mutation.
 * Armor with the first star effect "Unyielding" can add up to 3 to all stats, except Endurance, dependant on how low the player's health is.
 * Armor may have one of four third star effects that reduce weight. These effects stack (with perks) up to a cap of 90%:
 * Ammo weight reduced by 20%.
 * Food, drink, and chem weights reduced by 20%.
 * Junk weight reduced by 20%.
 * Weapon weight reduced by 20%.
 * This stacks with all specific weapon weight perks and the third star effect "Lightweight" in a way that allows the reduction to effectively reach 99%.

Power armor
In terms of carry weight, power armor sets the Strength of operators to 11, provided their Strength is below 11; useful for those who lack investment into Strength. In addition, components attached to power armor chassis are weightless.

However, any equipped armor beneath the power armor will have its effects nullified, such as those providing bonuses to Strength or carry weight. The operator also may not use unarmed weapons, nullifying use of those providing said bonuses. Power armor users must also have at least one fusion core on them at all times to use the armor properly, increasing one's weight when carrying more fusion cores.

Excavator power armor
From the entire roster of power armor available, the Excavator power armor is unique from the rest, in that it provides 100 carry weight. When equipping power armor that includes a full set of components from the Excavator family, the effect is applied. Its torso also quadruples ores mined from ore veins, except ultracite and uranium ores.

This power armor grants its bonuses in exchange for protective stats; when compared to other power armor, operators will have the least damage and energy resistances of any power armor.

Power armor mods
Like normal armor, power armor can be modified, and two mods are concerned in regards to carry weight:


 * Motion-assist servos - A torso mod that increases Strength by 2. Increases weight of component by 10%.
 * Calibrated shocks - A leg mod that increases carry weight by 50, totaling to 100 when modded into both legs. Increases weight of component by 20%.
