Fallout 76 legendary mods

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

Characteristics
Legendary items have one or more randomly determined special modifications, affecting combat or character stats. Legendary items may be earned as quest or Daily Ops rewards, looted from legendary enemies, bought from Purveyor Murmrgh or crafted with Legendary modules.

Occasionally, encountered enemies may spawn as legendary enemies. These enemies will be briefly cloaked with a green fog and will be identifiable by a star and the word "Legendary" in their nameplate. When killed, legendary enemies will drop a randomly generated 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 number and type of effects generated are not affected by any SPECIAL stats, such as Luck.
 * Legendary effects are randomly generated upon crafting or dropping. They cannot be found as loose mods.
 * Certain unique items have predetermined Legendary effects.
 * Legendary items cannot be scrapped at a workbench, but they may be placed in a legendary exchange machine for Legendary scrip.
 * Aside from their provided effects, Legendary items otherwise have the same statistics as non-Legendary items. They may be equipped with the same mods as non-Legendary variants.
 * Almost every Legendary item may be dropped, traded to other players or sold to vendors for caps.

Modifiers
Three tiers of legendary modifiers exist for both weapons and armor. A Tier 1 modifier appears on all legendary items, taking up the first "star." The modifier will be added to legendary weapon's dynamic naming as a prefix. Tier 2 modifiers comprise the second star of a legendary item and Tier 3 modifiers comprise the third. In general, Tier 2 and Tier 3 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 Tier 1 modifier.
 * A 2-star legendary will have a Tier 1 modifier and a Tier 2 modifier.
 * A 3-star legendary will have a Tier 1 modifier, a Tier 2 modifier, and a Tier 3 modifier.
