Ghoul Lords are vampiric undead who are grey in color. They are often found in the Arcane Sanctuary of Act 2 of Diablo II. They usually are found in groups, and attack with a type of Fireball that they shoot from a distance and erect Walls of Fire, and can also use the typical vampiric Leech-life Ball. These monsters will almost never break from combat, but given the design of the Arcane Sanctuary, where other monsters will frequently block melee access, they will prefer to hang back and utilize their range attacks to cause damage.
