Fallout 76 legendary mods

Legendary weapons and armor have 1 to 5 special combat/status modifiers (mods), and these items can only be generated by looting legendary enemies. For each legendary "star" an enemy has, that is the maximum possible number of mods any single looted item may have. There will always be at least 1 legendary drop on a legendary enemy with at least 1 mod, which could be either a legendary weapon or a legendary armor. Legendary enemies can drop multiple legendary items.

The specific type of legendary mod(s) on each item will be randomly generated from the options in the relevant tables below. The number and type of mods generated are not affected by any SPECIAL traits (e.g. Luck). These mods cannot be obtained elsewhere. You cannot craft/apply these mods for existing weapons, and they are not found in across Appalachia like mods for normal weapons or armor. Legendary items in Fallout 76 cannot be scrapped, or modified at all -- but they can be dropped, traded to other players, or sold to vendors. Otherwise, their durability (repair) and general use function like normal weapons and armor.
