Unrelenting Nightmare

The Unrelenting Nightmare is an extremely powerful, Ultra-tier Nightmare of a Cabal Ceremonial Bather that is encountered throughout the Derelict Leviathan.

Operation: Midas
The Unrelenting Nightmare can first be found in the Operation: Midas Mission. It is located in lower section of the Derelict Leviathan, below Calus's throne room, prowling up and down a bridge in the middle of the area. The Bather is completely invincible and cannot be wounded with any attacks. Eris Morn will warn the player to keep out of sight, and you will have to sneak past it to get to the other side. You can do this by heading over to the far-left or far-right sides of the room and taking the paths there, or you can hide behind the barriers along the bridge and wait for the Ultra to walk by, before running to your objective. You must destroy the Arc Conduit, which can be shot at through the small crack in the door, in order to fully open it and make your escape. If the Nightmare spots the player you at any point, it will rush towards you to slash at you with its Cabal Severus, which deals a massive amount of damage and can kill you in, at least, two hits.

Later on in the mission, when you are told flee Calus's throne room, the Unrelenting Nightmare will appear once again towards the end of the purple, crystalline hallway, to try and stop you from getting away. Like before, it possesses total immunity and cannot be hurt, meaning your only option is to keep running to your ship, where the mission ends.
