Fallout 76 conditions

Condition can refer to two things — either the condition of the character or the condition of their equipment.

Character condition
The most common character conditions found in Fallout 76 are poisons from Chems or from the environment, and damage from combat. Fallout 76 is currently the only game besides Fallout 4 in the Fallout series to include diseases.

Injuries

 * Crippled Arm
 * Crippled Leg

Needs
Similar to Fallout 4's Survival mode, player characters in Fallout 76 need food and water to survive. Depriving any of those needs will result in negative effects, while adequately satisfying them grants temporary positive effects.

Sleep
Unlike Fallout 4, sleeping is not necessary for survival in Fallout 76. However, sleeping in a bed or sleeping bag for 30 seconds will grant the player character the effects of Well Rested. Sleeping in a bed in one's C.A.M.P. with an ally present will instead grant the Kindred Spirit condition.

Instruments
Playing any musical instrument in Fallout 76 for 30 seconds will grant the player character the effects of Well Tuned.

Diseases
Similar to Fallout 4 survival mode, Fallout 76 features diseases the player character can contract. Each disease has negative effects, such as periodically increasing hunger.

Mutations
Fallout 76 also features mutations that have a chance of occurring on exposure to radiation from consumables, creature attacks, and irradiated zones. Mutations have a chance of being cured with RadAway. To protect desired mutations from RadAway, player characters can equip the second rank of the perk Starched Genes.

Queen of the Hunt rewards
Upon successful completion of the Queen of the Hunt daily quest, the player will receive a 4 hour long damage increase towards whichever cryptid they identified.
 * Flatwoods Knowledge
 * Grafton Knowledge

 * Snallygaster Knowledge
 * Wendigo Knowledge

Other

 * Encumbered
 * Meat sweats
 * Wisdom of the Mothman

Equipment condition
Equipment condition returns in Fallout 76 from Fallout 3 and Fallout: New Vegas; however, unlike in previous games, armor and weapons can be repaired using junk and crafting components at an armor workbench or weapons workbench. Alternatively, equipment can also be repaired without a workbench by using a repair kit or improved repair kit.

Equipment degradation
As equipment condition degrades, weapons will continue to do the same damage and armor will provide the same protection. When the equipment's durability runs out completely, though, it will be broken and cannot be equipped again until it has been repaired.
 * Weapons are unequipped and moved to your inventory once they break, forcing you to use your fists or equip a new weapon.
 * Armor remains equipped when it breaks, but no longer provides damage resistance. This allows for mods and legendary effects to continue functioning until the armor is unequipped, but the armor will need to be repaired in order to provide damage reduction or to make it equipable again if you take the armor off.
 * Unlike regular armor pieces, when a piece of your power armor breaks it will be unequipped from the power armor chassis and moved to your inventory. This has an influence on set bonuses like the carry weight bonus from Excavator power armor, which is only in effect when a complete set is worn, as well as the inherent damage reduction (7% per worn piece) and radiation reduction (15% per worn piece) of power armor. It also has a negative influence on carry weight, since power armor pieces on a power armor chassis have no weight.

Weapon condition degrades when your attack successfully hits an enemy or object which can be damaged, causing an estimated 0.25 - 1% loss in the used weapon's durability per hit.
 * Attacks which hit the environment or objects with no health/durability or which do not hit anything at all, will not count toward condition degradation.
 * Ranged weapon durability loss can occur when melee bashing with your gun, but otherwise it is per projectile/pellet. (Note that shotguns, pipe guns and certain other weapons may lose condition faster or have a lower maximum condition)

Armor condition degrades when you receive health damage from attacks or environmental dangers such as explosions. The amount of durability lost on worn equipment depends on how much damage is received and takes into account damage reduction from equipment, effects, consumables and perks.
 * Power Armor is a perfect example of how much damage reduction can make your armor last longer as it will likely lose way less durability than many pieces of regular armor with lower damage reduction.
 * Hazmat suits, which provide no damage resistance, suffer no condition degradation whereas the otherwise similar Chinese stealth armor provides damage and energy resistance and degrades when hit.

Value
The condition of equipment is also tied to its trade value in caps. As equipment loses durability, its value goes down until the cap value reaches zero when the item is broken. Items with better than 100% condition do not gain any additional caps value.

The Legendary scrip value is not influenced by item condition.
