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.

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, which can be carried and used outside of a player's camp or workshop.

Equipment degradation
As equipment condition degrades, weapons will do less damage and armor will provide less protection until the equipment's durability runs out completely, at which point it will state that it is broken and cannot be equipped again until 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 reduction. This allows for mods and legendary effects to continue functioning until the armor is unequipped, but still needs repairs to benefit from damage reduction or to make it equipable again if you take the armor off.

Weapon condition degrades upon your attack successfully hitting an enemy or object which can be damaged, causing an estimated between 0.25 - 5% loss in the used weapon's durability per hit.
 * Attacks which miss and hit the environment, objects with no health/durability or 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. (Not that shotguns, pipe guns and certain other weapons may lose condition faster or have a lower max condition)

Armor and outfit 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.
 * 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.

Value
The condition of equipment is also tied to it's trade value in caps. An item at 100% condition can utilize it's full intended damage or damage reduction, making it a valuable item, conv This means that as equipment loses durability, it's expected value goes down, down to an estimated 75 - 95% of it's expected cap value when broken. When repaired an item will return or even 200% repaired items being worth more than a broken
