Fallout 76 legendary enemies

Legendary enemies are enemies which possess special abilities and drop Legendary items upon death

Overview
Occasionally, certain foes with powerful buffs will appear. These legendary enemies will be identifiable by a star (★) and the nameplate prefix  "Legendary". When killed, legendary enemies will drop a randomly generated legendary item with at least one effect. For each star an enemy has, the randomly generated item they drop may have an equal number of legendary effects. When legendary enemies spawn, there is a brief window before they gain their stars. This process is initiated when the enemy becomes veiled with a temporary green fog. If the enemy is killed before the stars appear on its nameplate, then it will not yield any legendary items.

Characteristics

 * When their HP is reduced to 40% or below, all legendary enemies will regen 99,999 HP or until they reach their max HP.
 * Depending on what type of enemy they are, Legendary enemies possess bonus abilities:
 * Some deal poison damage over time on their melee attacks
 * Some gain enhanced accuracy
 * Some deal bonus damage
 * Robots will initiate a self-destruct sequence upon dying.
