Lore

Gameplay

Nightmare Containment is a horde-defense gamemode in which the players must defend the Nightmare Harvester from waves of Scorn and Cabal enemies. The event takes place in three of four areas of The Castellum, each corresponding to an entrance to a part of the ship. The event will begin in front of either The Royal Pools, The Royal Gardens, or the Gauntlet and will make their way to one of the other two locations, progressively getting more difficult, before ending in a boss battle that always takes place in front of the entrance to Emperor Calus's Throne Room. Each Nightmare Containment consists of three tiers with four phases each.

Tiers One and Two

The event/next tier begins when a play places a Nightmare Harvester on the designated location. There will also be a place to plant a Rally Banner nearby when first starting the activity. During this phase, players are tasked with binding Shards of Dread by killing combatants and depositing Cores of Dread into the Nightmare Harvester. Scorn will constantly spawn in order to impede progress and swarm the Harvester. There are also Overload Chieftans that spawn in close to the Harvester with a small group of Scorn and will attempt to steal Shards of Dread. Periodically, large scorn Raiders named "Dread Bearers" will spawn. Killing these Dread Bearers will drop Cores of Dread, which when deposited, will give a large amount of Shards of Dread. In Tier Two, the Dread Bearers can also be large Abominations. Every so often, the Harvester will also produce a Scythe Relic which can be used to deal damage to enemies. Once Harvester has enough Shards, this phase will end.

The second phase begins when Calus attempts to impede player progress by summoning a large amount of Cabal close by. During this phase, no Scorn will spawn. Players must kill Psions named "Egregore Atavists" which are protected by "Atavist Illusions." When the illusions are defeated, the Atavists will spawn in which a psionic shield around them that blocks incoming damage, forcing players to walk into their bubble to kill them. The amount of Egregore Atavists that spawn increases from two to four when in Tier Two. Once all the Atavists are dead, the second phase will end.

The third phase is a repeat of the first. After the Harvester has had enough Shards, the fourth phase will begin. Calus will summon a powerful Cabal boss. It will be Valus Thu'ur, Vessel of Nightmares, a Colossus for Tier One or Primus Or'sek, Vessel of Nightmares, a Centurion for Tier Two. When the boss reaches half health, the boss will pull up a immunity shield that cant be deactivated by destroying Resonant Splinters. The amount of Resonant Splinters needing to be destroyed increases from two to four in Tier Two. After this boss has been defeated, the event will move onto the next tier and a box of ammo that refills Heavy and Special ammo will appear.

Tier Three

Tier Three is the final boss of Nightmare containment. The boss and mechanics rotate on a weekly basis. Throughout all three, constant waves of Scorn will be spawning to impede player progress.

Nightmare of Elykis, The Mechanist is a large Scorn enemy. After dealing one third of its health, Elykis will pull up an immunity shield and six resonant splinters will spawn around her. Once all are destroyed, two Abominations named "Emissary of Elykis" will spawn beside it. Killing these two Abominations takes down its shield. This mechanic repeats once more after the next third of its health is dealt.

Nightmare of Anaphex, Sworn to Otzot is a large Psion. Periodically, Anaphex will unleash a weave of psonic energy which traps players in a cage. In order to escape, players can shoot one of the circles that make up the cage. If a player is not freed in time, they die. When Anaphex's health is reduced by a third, it will disappear and several Egregore Atavists will spawn around the area. Killing them all causes Anaphex to reappear. This mechanic repeats once more after the next third of its health is dealt.

Nightmare of Navota, Eir-Spawn is a large Hive Wizard . After dealing one third of its health, Navota will become immune and summon two Dread Bearers. Killing them and depositing their Cores of Dread will bring down her shield. This mechanic repeats once more after the next third of its health is dealt.
