Nightmare of Arguth, the Tormented

The Nightmare of Arguth, the Tormented is the Nightmare of a Hive Ogre—created by the Lunar Pyramid—that serves as the boss of the K1 Revelation Lost Sector on the Moon.

Gameplay
The Nightmare of Arguth will initially appear as an etheral manifestation, immune to all damage. In order to fight it, the player must kill three Tormented Servant Nightmares, and destroy the three crystals they protect, scattered around the area. Once this is done, the crystal above Arguth will be vulnerable, and destroying it will manifest the Nightmare. As soon as it appears, Arguth will start attacking the player, and summon a Nightmare Acolyte as well as several Hive reinforcements. Every third or so of its health, more reinforcements will appear. Arguth fights much like a normal Ogre, and can be quickly brought down by heavy weapons.
