Fallout 76 legendary mods

In Fallout 76, legendary weapons and legendary armor, collectively known as legendary items, are items with special, permanent modifiers applied.

Legendary items have one to three special modifiers, affecting combat or character status. They may only be found with random effects, being earned as quest or Daily Ops rewards, looted from legendary enemies, or bought from the Purveyor.

Normal enemies may occasionally spawn as legendary enemies. When killed, legendary enemies will drop at least one legendary item with at least one effect. For each legendary "star " an enemy has, a dropped legendary item may have up to that amount of effects. The specific type of effects a legendary item will be randomly generated from the options in the relevant tables below. The number and type of effects generated are not affected by any SPECIAL traits such as Luck. Legendary effects may only be generated randomly and cannot be obtained elsewhere. The player character cannot craft or apply legendary effects to existing items. Legendary modifiers are not found as loose mods like standard modifications for weapons or armor. Legendary items in Fallout 76 cannot be scrapped, but they can be modified, dropped, traded to other players, and sold to vendors or the legendary exchange machine. The durability and normal statistics of legendary items remain the same as non-legendary weapons and armor.

Characteristics
Three types of legendary modifiers exist: prefix, major, and minor modifiers. A prefix modifier appears on all legendary items, taking up the first "star." The name of a legendary weapon will include the prefix modifier's name. Major modifiers comprise the second star of a legendary item and minor modifiers comprise the third. In general, major and minor modifiers don't affect a legendary item's name. Legendary weapons and armor use different sets of modifiers and cannot use modifiers from the other's item type.

Although additional legendary modifier slots exist (Tier 4 and Tier 5 modifiers, respectively), 4 and 5-star legendary items are disabled. However, the Tier 4 and Tier 5 legendary effects are used in many of the quest-specific unique legendary weapons and armors, such as Perfect Storm or All Rise.

Legendary items can have a maximum of one modifier per category, based on the number of stars:
 * A 1-star legendary will have a prefix modifier.
 * A 2-star legendary will have a prefix modifier and a major modifier.
 * A 3-star legendary will have a prefix modifier, a major modifier, and a minor modifier.

Special event modifiers
Currently, only the Cursed effect is available for the harpoon gun, pickaxe, and shovel and only from the A Colossal Problem event added in the Wastelanders update. Special event modifiers are in addition other effects and can be a forth effect on a three-star legendary. This special modifier also supersedes the all above modifier names, i.e. a harpoon gun will have both the executioner's and cursed modifiers and will be named a Cursed Harpoon Gun.

Minor modifiers

 * Item adds modifier name as prefix

Set bonus modifiers
Set bonus modifiers are effects that only take effect once a full set of the respective armor is equipped. Set bonus modifiers are in addition other effects and can be a forth effect on a three-star legendary.
