Diablo Immortal Lord Martanos: Location & Boss Fight

Diablo Immortal’s mechanics are similar to its predecessors, such as playstyle and leveling up. However, there are new additions such as Helliquary, extracting Essence, and joining shadow Factions, which have tasks like Lord Martanos in Diablo Immortal.

How to Find & Defeat Lord Martanos

These are the steps I took to locate and defeat Lord Martanos:

• Located near the Frozen Descent waypoint. 
• Activate his grave altar before engaging in a challenging battle, as Martanos is one of Diablo Immortal’s toughest bosses.
• Martanos unleashes deadly AoE attacks, requiring persistence, especially on higher difficulty settings.
• Consider the game’s difficulty rewards before lowering them.
• Defeat Martanos within a 30-minute window for optimal results.

Martanos features a persistent shield, nullifying incoming damage and releasing a high-damage AoE attack in a short radius. When tackling this boss with teammates, include long-range characters in your composition. Fight Lord Martanos to obtain the Zakarum Sigil, essential for altar activation. The sigil adds a stunning effect and boosts damage against Ancient Nightmare’s shield by 20%.

Activate Altars without Zakarum Sigil; each takes a minute. Despite seeming impractical, use them. Instruct the team to scatter around Martanos to avoid simultaneous AoE damage. When Martanos engages a player, direct short-ranged characters to strike decisively and quickly retreat.

Defeating Ancient Nightmare

Here’s the path I would recommend you to defeat the Ancient Nightmare:

• After defeating Lord Martanos in Diablo Immortal, you will receive rewards, but most importantly, you will get Zakarum Sigil.
• It was the reason why you awakened Martanos and put him back to sleep.

To defeat Ancient Nightmare, move ahead of him at the start and activate the Altar and Sigil. The Altar depletes his shield faster within its range, giving you more time to attack. Stay ahead to keep him within the Altar’s proximity; otherwise, you can’t damage him.

Once the shield is down, Ancient Nightmare attacks; be prepared for AoE attacks. Protect teammates from AoE damage by activating the Altar. Defeating him yields a treasure chest with high-tier loot near his corpse, ensuring rewards even if you join late, with a minimum reward of Enchanted Dust.

• Some players who like to farm these quests for high-tier loot should do this more often.
• In the beginning, you can complete these battles with the Ancient Nightmare and Lord Martanos on low difficulty.
• When you learn all the tricks, start increasing the difficulty level to get better rewards once they are defeated.
• You will also see Ancient Nightmare’s reemerging time on the screen, but if it’s past midnight, you have to wait till 8 AM server time. 

Tips & Tricks Against Lord Martanos

Many might overlook this, but your teammates matter a lot in these battles. I suggest you to pick teammates who have quite an experience of side quests and have an appropriate level. Also, make sure that there is not too much skill disparity so the coordination stays on point. 

Keep some health potions in your inventory, as Lord Martanos and Ancient Nightmare’s AoE attacks can be deadly. To outlast them, you will need health potions so you can consume them whenever you are low. Also, try to play defensively and smartly rather than rushing in.

Don’t forget that communication matters. When the situation gets tough, you and your teammates will need callouts and information. If your teammate is busy fighting someone else while the boss is about to attack him, let him know about it and try to cover him. 

That is all about how to defeat Lord Martanos and the Ancient Nightmare. Now you know what to expect, plan accordingly so the battles go smoothly. Keep these battles as a priority because you will be getting high-tier loot, and once you master it, play on high-difficulty for better loot.
