Lights Out (Holding Pens)

Buff applied to most adds in this encounter. The only reliable physics-based abilities are knockbacks, though it is important to note that any stun or root effect of the ability or a relevant utility will not have any effect.

Buff applied to Crimson Stalker, Felshade Hunter, Shadow Reaper, Rampaging Charger and Incendiary Shriek. Along with Augmented Resistance, these buffs make it very difficult to outrun the add waves in the encounter.

Regular attack of Crimson Stalkers. Applies Paralyzing Venom debuff to target.

Debuff applied by Crimson Stalker's Envenomed Bite. Reduces movement speed by 60% in Story Mode or 90% in Hard Mode. Duration is 1.1 seconds but due to slow is typically continually refreshed by Envenomed Bite attacks by Crimson Stalkers until killed. Can be ignored via abilities that provide immunity to slow effects (e.g., Hold the Line, Force Speed w/ Egress utility, etc.)

A periodic cast ability by Crimson Stalkers, the pool is placed directly under the enemy when the cast is completed.

Debuff applied by players standing in Hydrochloric Pool cast by Crimson Stalkers. The debuff is removed as soon as you move out of the pools AoE. The debuff reduces the following stats by the following amounts:

• Healing Done: 20% Story Mode / 50% Hard Mode / 95% Nightmare Mode

• Damage Done: 20% Story Mode / 50% Hard Mode / 95% Nightmare Mode

• Force/Tech Resistance: 20% Story Mode / 30% Hard Mode / 95% Nightmare Mode

• Melee/Ranged Defense: 20% Story Mode / 30% Hard Mode / 95% Nightmare Mode

Increases movement speed of Incendiary Shriek adds to 160%.

When the Incendiary Shriek dies, either instantly by using a Flare or after being killed conventionally in Hard Mode, it drops a yellow circle on the ground for 4 seconds. After 4 seconds, the circle explodes and applies a knockback to nearby players. Any player who entered the circle during those 4 seconds receives a stack of the Corrosive Rain DoT.

DoT received by standing in Impending Burst (yellow circle left after killing Incendiary Shriek adds). Last 60 seconds and ticks once every 3 seconds dealing approximately 1.3% of maximum health per tick per stack of the DoT. DoT can stack once per yellow circle that is stood in by the player.

Knockback damaging ability cast by Rampaging Charger. 0.7 second cast time. Briefly stuns the player after the knockback.

Additional knockback ability of Rampaging Charger when it charges a target.

Ability has a 2 second cast time, a 20 second cooldown and a 6-15m range. Is not used when the player with aggro is inside a flare AoE. If cast completes, Felshade Hunter enters stealth for 3 seconds and then utilizes Extermination Protocol.

Debuff applied to target when Felshade Hunter attacks from stealth after casting Ghost in the Darkness. Increases damage taken by 50% in Story Mode and 100% in Hard Mode.

Debuff applied by a flare's AoE circle. Lasts 15 seconds and can stack up to 3 times.

The Shadow Reapers have a status effect called Nocturnal that applies buffs to maximum health, movement speed, and damage dealt when they are not standing inside a flare's AoE circle.

Stun attack used by Shadow Reapers. Has a 24 second cooldown and is not used when the Shadow Reaper is affected by a flare.

Debuff applied by a flare's AoE circle. Lasts 15 seconds and can stack up to 3 times.

Basic attack by Warden Droid. Has 1 second channel and a 3 second cooldown.

Buff to Warden Droid that locks a nearby console. An energy beam will connect the Warden Droid to the console, which will not be usable until the Warden Droid is destroyed.

Flares can be picked up inside the Holding Pen C Specimen Processing room, and again inside the generator shed if needed. The buff will have a number corresponding to how many flares the player currently holds and will generate a temporary ability bar with the Ignite Flair ability.

Temporary ability granted by holding at least one CI-Dark Control Flare. The ability has a 1 second cast time and a 20 second duration.

Buff / debuff applied by standing inside the AoE of the CI-Dark Control Flare (blue AoE circle). The effect has a duration of 2.1 seconds and is refreshed upon expiration if the target is still within the AoE. The debuff has a wide range of effects, but in general it protects players from certain enemy special ability, prevents affected enemies from using certain abilities, immediately kills Incendiary Shrieks, and debuffs most enemies to deal less damage and take more damage during its duration.

Buff applied when a player drops flares to be picked up by other players.

Item that can be picked up inside the Holding Pen C Specimen Processing room. One use applies a movement speed buff and immunity to movement impairing effects, which effectively makes it grant similar benefits to the Vanguard ability Hold the Line or Powertech ability Hydraulic Overrides. A second use grants additional benefits to DPS and tanks. A third use has not effect in Story Mode but is fatal in Hard Mode.
