Night Lords are vampiric undead that are grey in color. They are often found in Act III, spawning in the Kurast Sewers, Travincal, the dungeons of Upper Kurast, the Forgotten Temple and Forgotten Reliquary. They usually are found in groups, and attack with a type of Fireball that they shoot from a distance and erect Walls of Fire, summon Meteors and can also use the typical vampiric Leech-life Ball. These monsters will prefer to hang back and utilize their range attacks to cause damage, and occasionally flee when their health reaches critical levels.
