Diablo Immortal Ancient Nightmare: Location & Boss Fight

Diablo Immortal will have you fighting a great number of bosses, like the Vitaath boss, and a handful of them can be found in different zone events. These events can help you with testing your skills against powerful bosses.

The best part is that you also get different rewards for completing these events, ones which you can’t find anywhere else. One of these events is the Diablo Immortal Ancient Nightmare zone event. A lot of players don’t know about this event, and if you’re one of them, you’re missing out on a lot. 

As you complete these events, you’ll acquire rare rewards that can help you become stronger in the game. As for the Ancient Nightmare event in Diablo Immortal, it will have you fighting Ancient Nightmare, a powerful boss who isn’t easy to take down.

How To Activate Ancient Nightmare Zone Event

If you’re interested in activating the Diablo Immortal Ancient Nightmare zone event, you will need to visit the Mount Zavain zone. The zone can be accessed every 2 hours, from 8 AM to midnight server time. If you try to visit the zone at any other time, you won’t be able to participate in the event. Furthermore, as it refreshed every 2 hours,  you might need to wait at times. 

Where To Find Lord Martano

Now, before you can go ahead and fight the powerful Ancient Nightmare boss, you will first need to pay a visit to Lord Martanos, who is another tough enemy that won’t go down easily. You can’t avoid facing this enemy as you need an item to defeat Ancient Nightmare, and it can only be acquired by taking down Lord Martanos.

While Lord Martanos isn’t as deadly as Ancient Nightmare, you will still need to be careful around him. We recommend that you get your hands on some of the best gems in Diablo Immortal, as these can help you boost your performance in combat.

Lord Martanos isn’t walking around anywhere or guarding anything, unlike some of the other enemies present in the game. Instead, he is peacefully resting in his grave, and you’ll need to go and disturb him. 

The grave of Lord Martanos in Diablo Immortal can be found west of the Frozen Descent waypoint. You can activate the fight there and defeat him to acquire the Zakarum Sigil. We’ll explain later where you’ll be using this item, but it is recommended that you fight Lord Martanos a good number of times to get a couple of them.

How To Defeat Diablo Immortal Ancient Nightmare Boss 

Now that you have added a bunch of Zakarum Sigils to your inventory, it’s time to head for the Diablo Immortal Ancient Nightmare boss. The boss is found patrolling the Misty Valley, an area that is located at the center of Mount Zavain. If you visit the area and can’t find Ancient Nightmare walking around, wait for some time as he will eventually appear. 

Focus on Destroying Its Shield 

After you encounter this powerful boss, you’ll instantly notice that he has a powerful shield protecting him from all incoming attacks. However, the annoying thing about the boss’s shield is that it does not only protect him from attacks but also lets him launch an AoE attack that deals damage to anyone caught inside the radius. Therefore, your first priority will be to destroy the boss’s shield, as you won’t be able to deplete his health otherwise.

Now, remember we talked about how the Zakarum Sigil can be used to defeat Diablo Immortal Ancient Nightmare boss? Well, there are multiple altars in the area where you’ll be fighting the boss, and these can be activated by using the Zakarum Sigil.

Your main goal here is to activate the altar whenever the boss is near to stun him instantly. In this state, Ancient Nightmare won’t be able to move a single muscle, and you will get an opportunity to land multiple attacks on him.

Ancient Nightmare Event Objectives 

When completing the Ancient Nightmare event, the following are some mission objectives you need to achieve in order to be successful.

  • The first objective is to set the World Difficulty to Hell. You can only access the event if your difficulty is set to hell. Go to Westmarch and open your map to set your World Difficulty to Hell 1. 
  • The second objective is to defeat Lord Martanos and farm Zakarum Sigils from him. However, this is optional. 
  • Next, you have to wait at the Misty Valley Waypoint located in Mount Zavain and wait for the event to start. 
  • Finally, you just have to fight Ancient Nightmare and collect the rewards he drops to level up in Diablo Immortal. 

Don’t Blindly Activate The Altars 

However, keep in mind that you will need for the boss to come near the altar before you activate it. Otherwise, you’ll miss out on the opportunity to stun him, which might even lead to the boss attacking you and sending you to your grave. Therefore, don’t try to rush the process and focus on timed activation.

If you have other players fighting alongside you, it will be wise first to let them activate the altars. It is because those who don’t have any Zakarum Sigils in their inventory can activate an altar once for free. Therefore, make sure you let them do it first, as you’ll waste your Sigils otherwise. You will need to keep on repeating the process until you have successfully managed to destroy his shield. Afterward, keep on launching attacks on the boss until his health bar drops to zero.

Additionally, keep in mind that after you destroy the shield of Ancient Nightmare, he will become more aggressive and will start launching powerful attacks that can eliminate you quickly. Therefore, make sure you prepare yourself for the final part of the Diablo Immortal Ancient Nightmare event.

If everything is too difficult, you can try lowering the difficulty level in Diablo Immortal. Another reason why you might not be able to defeat the boss could be that you have the wrong class selected for your character. We have a detailed guide on the best solo classes in Diablo Immortal, and you can check it out to see which one suits your playstyle the most. 

After you have successfully managed to defeat the boss who was feared in the entire Mount Zavain region, you will get rewarded with a treasure chest. The chest will contain rare and powerful items that you can’t acquire from anywhere else in the game. Furthermore, you will also get an amount of Enchanted Dust, so you’ll be satisfied with the results. 

This marks the end of our Diablo Immortal Ancient Nightmare zone event guide. As you can see, the event will have you fighting two powerful enemies, and both of them won’t go down so easily. However, considering the type of rewards you’ll get for defeating the final boss, the trouble is worth it.

Make sure that you’re well equipped for both fights, as you might get killed over and over again otherwise. You can also participate in this zone event as many times as you like to get tons of high-tier loot.
