Nightmare of Volniks, Deathkeeper

The Nightmare of Volniks, Deathkeeper is the Nightmare of a Major Fallen Captain, created by the Lunar Pyramid. It serves as the target of VIP Patrol mission, and is located at the Lunar Battlegrounds.

Gameplay
The Nightmare of Volniks can be found at the Lunar Battlegrounds on the Moon, after you have acquired the specific patrol mission from Sorrow's Harbor. Upon arriving at the location that it directs you to, you will find the target alongside a couple of lesser enemies, possibly engaging nearby Hive in combat. The Captain possesses a great deal of resilience against attacks, but it can be taken out much faster if you pick up the Unstable Essence dropped from killing its allies, which will grant you a temporary damage buff against Nightmares.
