Fallout 76 armor mods

Usage
In Fallout 76, junk items are used to craft new armor and armor modifications at an armor workbench. Investment in the Armorer perk is required to craft higher quality modifications. Finding plans unlocks further modifications at the workbench, and scrapping armor pieces has a chance to unlock modification options. Additionally there are fixed locations for a modification boxes to potentially spawn, although the ones that do are randomized, and certain vendors may sell armor modifications.

Armor modifications with gameplay attributes can be applied to the chest, arms, and legs of any set of armor. These include material modifications, which improve damage and energy resistances, and miscellaneous modifications, which have a variety of effects such as increased carry weight or increased radiation resistance. A given armor piece can only have one material modification and one miscellaneous modification. Additionally, there are cosmetic modifications which alter armor appearance but do not have an effect on function. Helmets can only receive cosmetic be modifications. Underarmor can receive lining modifications which increase resistances and certain S.P.E.C.I.A.L. points (though the S.P.E.C.I.A.L. points provided from underarmor does not affect the player character's base S.P.E.C.I.A.L., which determines the number of perk cards they can equip). Helmets can only receive cosmetic modifications.

Power armor usage
Junk items are also used to craft new power armor and power armor modifications at a power armor station. Similar to standard armors, finding plans unlocks further modifications at the power armor station. There are are fixed locations for a modification boxes to potentially spawn, although the ones that do are randomized, and certain vendors may sell armor modifications.

Power armor modifications with gameplay attributes can be applied to the helmet, torso, arms, and legs of any set of armor. These include modifications such as increased carry weight, the addition of a jet pack, or highlighting enemies. Additionally, there are cosmetic modifications which alter armor appearance but do not have an effect on function. Helmets also receive headlamp modifications which alter brightness and color of the light produced.
