Ancient Nightmare is shielded and invulnerable for a short time upon spawning. The shield deactivates by lighting the surrounding Altars, which temporarily stun and weaken the Ancient Nightmare while in range. Consume Zakarum Sigils to reset the restoration time of Altars and deal significant damage to the Ancient Nightmare’s shield.

When does the Ancient Nightmare spawn?

The Ancient Nightmare spawns every Wednesday and Friday at 12 p.m., 8:30 p.m., and 10 p.m. server time.
