Egregore Atavist

Egregore Atavists are Nightmares of Councilors that be found on the Derelict Leviathan.

Gameplay
Egregore Atavists appear as part of Nightmare Containment. During the first two tiers, they will appear in the second phase, two in tier one and four in tier two. If the tier three boss is the Nightmare of Anaphex, Sworn to Otzot, three will appear every third of its health. They will be hidden until their Atavist Illusions are defeated, which will cause them to appear. Like other Councilors, they project a shield that makes them immune to ranged attacks, requiring Guardians to get close and hit them with a Melee attack to kill them. One strike is enough to put them down. Defeating all the Atavists will allow the tier or boss fight to progress.
