Monsters must be of this level to drop the item. Item level (ilvl): Used in many in-game calculations.

The partial set bonuses are notoriously weak for this set, so it’s usually used one item at a time, or all at once. The armor is extremely difficult to find and has a gigantic strength requirement, but the rest of the set can be obtained without too much difficulty. The full set is for a Barbarian-only, with the helm being a Barb-specific item, but the other gear is useful for a variety of character types. Immortal King is designed for a melee fighter, with armor, mace, helm and boots. The set is also very difficult to find mainly the body armor and the ogre maul since it requires a difficulty of Hell to gain access of having a chance for a drop and mostly drops from act III and IV final bosses as well as Barbarian Territory on selected unique monsters. The set is the only set item that completes all the six important vestments in a character: helm, body armor, belt, gloves, boots and a weapon and also has one of the most bonuses gained (if collected many) with each item and also the full set bonus. As powerful as He could be, so is his armor and weapon left behind. The Immortal King set once belonged to the Barbarian-God name Bul-Khatos. Immortal King Notes Immortal King – Click to Enlarge
