Players that want to take on the Ancient Nightmare in Diablo Immortal will need to obtain some number of Zakarum Sigils. Indeed, these items are the only way remove the shields from this ferocious world boss, making them quite important. For those players that are unclear about where they can obtain Zakarum Sigils in Diablo Immortal, this guide contains full details on their source.
Diablo Immortal: Zakarum Sigil Location
Zakarum Sigils are earned by defeating Lord Martanos, a boss that is northwest of the Zakarum Graveyard in Mount Zavain. Upon arriving at this location, Diablo Immortal players will find a tomb that contains the Martanos Altar, and they can summon the lord from it every 30 minutes. For full clarity, the position of the Martanos Altar has been marked on the map that is below, and fans can receive a Zakarum Sigil every time that they defeat its associated boss.
With some Zakarum Sigils in hand, players should wait for Diablo Immortal's Ancient Nightmare to spawn and then head to the Misty Valley in Mount Zavain. After locating the boss, fans should follow it around until it is near to one of the Altars that are scattered across the area. Putting Sigils into these Altars will cause the structure to emit a dome of light, which will make it possible to damage the Ancient Nightmare. This will only be temporary, though, and players will need to activate several Altars before everything is said and done.
With respect to what fans will earn for ultimately bringing down the Ancient Nightmare, the primary reward is Nilfur's Precision Vessel. This is one of the Legacy of the Horadrim Vessels, and players that take it Iben Fahd’s Sanctum will earn some extra armor penetration for their Diablo Immortal characters. Fans can also gain access to a chest upon killing the Ancient Nightmare, though that reward is certainly not as unique as the vessel.
To note, players should not feel as though they need to have enough Zakarum Sigils to cover the entirety of the Ancient Nightmare fight by themselves. This is because there are a typically a number of players working on the event at the same time, and some of them are likely to have a Sigil or two in the inventories. That said, ARPG fans are still advised to do some amount of preparation before heading to the fight in order to avoid any possible issues.
