Dark Mist

The Dark Mist fogging up a map.

The Dark Mist is a recurring feature in every match, and cannot be completely removed. For both the Killers and Survivors, the mist adds a sense of uncertainty to a player's location, making it ideal for Survivors to attempt to hide in plain sight and escape the Killer.

However, Killers that rely on stealth actually benefit from the mist, especially The Wraith, The Shape and The Pig. The mist makes them harder for Survivors to spot from a distance.

Thickness

The thickness of the Dark Mist can be altered with Reagent Offerings.
Clear Reagent and Murky Reagent mark the minimum and maximum achievable values of thickness:

Offering	Rarity	Effect	Stacks?
Clear Reagent	Common	Clears the Dark Mist (but not completely)	Yes
Faint Reagent	Common	Slightly thickens the Dark Mist	Yes
Hazy Reagent	Uncommon	Moderately thickens the Dark Mist	Yes
Murky Reagent	Very Rare	Considerably thickens the Dark Mist	Yes

Stackable?

Reagent Offerings can be combined freely as they all stack amongst themselves. Possible combinations and their resulting mist thickness are:

Combo	Equal to
Clear Reagent + Faint Reagent	Default thickness
Clear Reagent + Hazy Reagent	Faint Reagent
Clear Reagent + Murky Reagent	Hazy Reagent
Faint Reagent + Hazy Reagent	Murky Reagent
