Diablo Immortal Ancient Nightmare: Location & Boss Fight

Diablo Immortal Ancient Nightmare zone event can help you acquire some high-tier loot by taking down a powerful boss.

If you’re interested in activating the Diablo Immortal Ancient Nightmare zone event, you must 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 refreshes every 2 hours, you might need to wait at times. 

Key Takeaways
  • Diablo Immortal features various events and bosses, including “Ancient Nightmare.”
  • “Ancient Nightmare” can only be activated during specific hours, from 8 AM to midnight, with intervals of every 2 hours.
  • To engage in this event, players must first defeat Lord Martanos, located at Frozen Descent.
  • Defeating Lord Martanos is essential for farming Zakarum Sigil.
  • Once enough Zakarum Sigil is collected, the boss spawns with a shield and powerful attacks.
  • To defeat the boss, players need to use Zakarum Sigils at different altars, stunning the boss and allowing them to attack.

Where To Find Lord Martano

Now, before you can go ahead and fight the powerful Ancient Nightmare boss, I suggest you 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.

Based on my gameplay experience, to find Lord Martanos in Diablo Immortal and acquire the Zakarum Sigil:

  1. Location: Lord Martanos is not roaming or guarding any specific location but is resting in his grave.
  2. Grave Location: Head west of the Frozen Descent waypoint to find Lord Martanos’ grave.
  3. Initiate the Fight: Activate the fight at his grave, and defeat him to obtain the Zakarum Sigil.

I recommend you to battle Lord Martanos multiple times to collect several Zakarum Sigils. These sigils are crucial for a future encounter, specifically against the Ancient Nightmare boss in the game.

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.

How To Defeat 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.

Here’s the path I took to defeat the Ancient Nightmare boss:

  1. Locate the Ancient Nightmare: You’ll find the Ancient Nightmare patrolling the Misty Valley, which is at the center of Mount Zavain. If the boss isn’t present when you arrive, wait for a while as he will eventually appear.

  2. Focus on Destroying the Shield: Prioritize destroying the boss’s powerful shield, which not only protects against all incoming attacks but also enables the launch of area-of-effect (AoE) attacks. You can’t damage the boss’s health until the shield is eliminated.
  3. Use Zakarum Sigils: Defeat the Ancient Nightmare by utilizing Zakarum Sigils found at scattered altars in the boss battle area. Activate these altars using the Zakarum Sigil, stunning the boss when he’s near an activated altar, rendering him immobile.
  4. Attack While Stunned: Take advantage of the stun effect from the activated altar to land multiple attacks on the Ancient Nightmare. This is the window of opportunity to deal damage to the boss.

Your main goal here is to activate the altar whenever the boss is near to stun him instantly. I experienced that, 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 I would like to mention that you need to achieve to be successful.

  1. Set World Difficulty to Hell: Ensure your World Difficulty is set to Hell. You can do this by going to Westmarch and adjusting the World Difficulty to Hell 1 on your map.
  2. Defeat Lord Martanos: This is optional but recommended. Defeat Lord Martanos to farm Zakarum Sigils from him.
  3. Wait at Misty Valley Waypoint: Head to the Misty Valley Waypoint in Mount Zavain and wait for the event to commence.
  4. Fight Ancient Nightmare: Engage in battle with Ancient Nightmare and collect the rewards dropped by the boss to progress in Diablo Immortal.

Other Tips

A few additional tips I want to highlight for the event:

  • When activating altars, wait for the boss to come near them to stun him. Rushing the process may lead to the boss attacking you.
  • If other players are present, let them activate the altars first, as players without Zakarum Sigils can activate an altar once for free.
  • After breaking Ancient Nightmare’s shield, be prepared for his increased aggression and powerful attacks.
  • If you find the event too difficult, consider lowering the difficulty level or choosing a character class better suited to your playstyle.
  • Successfully defeating Ancient Nightmare will reward you with a treasure chest containing rare items and Enchanted Dust, unique to this event.

This concludes the Diablo Immortal Ancient Nightmare zone event guide. You’ll face two formidable enemies, and they won’t be easy to defeat. However, the rewards for conquering the final boss make the effort worthwhile. Ensure you’re well-equipped for both fights to avoid repeated deaths. Participate in the zone event multiple times to accumulate high-tier loot.
