While Lord Maranos can drop random rewards D2R ladder items, what really piques your interest is his guaranteed drop: a Zakarum Sword. What is the significance of that drop? That is because they make it easier for you to defeat the difficult Ancient Nightmare.

First and foremost, you need to be aware that you can only find the Ancient Nightmare on Wednesdays and Fridays at noon, 8:30, and 10 p.m. (local server time). If you try to find the supervisor at a different time, you won't be able to find him or her, which will make you extremely discouraged.

However, head to Mount Zavain's Misty Valley if you happen to be playing Diablo Immortal at the right time. The Ancient Nightmare's patrols surround the Misty Valley Waypoint. If you are in the general area, you should receive a message indicating that the boss has been summoned and that you can automatically navigate there. In addition, a massive, Xenomorph-like being encircled by a glowing shield serves as the boss. It is hard to miss.

The fight against the Ancient Nightmare is not always easy. In order to actually begin harming the Old Bad Dream, the fight expects you to destroy his shield buy d2r items. Even though the Ancient Nightmare's attacks are simple, it will take a long time for that shield to fall and start losing health. You might get to the point where you think nothing can happen.
