The Dark Mist, also known and referred to as "The Black Fog" or just "The Fog" is a recurring feature in every trial of Dead by Daylight .
The Dark Mist featured throughout the Trial Grounds appears to be a lesser variant of the Black Fog surrounding the Realm pockets and is one of The Entity's many manifestations.
For both the Killers and the Survivors , The Fog adds a sense of uncertainty to a Player's location and their surroundings, making it ideal for Survivors to attempt to hide in plain sight and escape the Killer, but also making it ideal for stealth Killers to approach unsuspecting prey. It is a very ambivalent feature of the Game.
The thickness of the Dark Mist can be altered with the Reagent Offerings.
"The Mist rolls in, traps all in its deep madness.
"Paralysed, I stand in the cold as death lingers."
"The Mist is alluring, hypnotising.
"The Mist seems to protect us from the beast, but it is a poison, a cancer, filling us with darkness and insanity." — Unknown, Notebook
The Reagent Offerings can be combined freely as they all stack amongst themselves. Possible combinations and their resulting mist thicknesses are as follows:
|Clear Reagent + Faint Reagent||Slightly less thickness|
|Clear Reagent + Hazy Reagent||Default thickness|
|Clear Reagent + Murky Reagent||Faint Reagent|
|Faint Reagent + Hazy Reagent||Murky Reagent|
For each of the Reagent Offerings, there exists an unused Vial equivalent of the same name. It is unknown if the Vials have the same or different effects as their corresponding Reagent or if the icons are intended to replace the Reagent ones at some point:
|Clear Reagent||Default Thickness||Faint Reagent|
|Hazy Reagent||Murky Reagent|
|Alarm Clocks||Bear Traps||Breakable Walls||Cages of Atonement|
|Chests||Crows||Dark Mist||Exit Gates|
|Lockers||Moonlight||Pallets||Pools of Devotion|
