At the start of the Trial, 4 random Hooks are changed into Scourge Hooks:

The Auras of Scourge Hooks are revealed to you in white.
Each time a Survivor is unhooked from a Scourge Hook, the following effects apply:

The Auras of all other Survivors are revealed for 5/6/7 seconds.

"Each time the Obsession loses a Health State, Remember Me gains 1 Token:

Increases the Opening time of both Exit Gates by 4 seconds per Token, up to a maximum of 8/12/16 additional seconds.
The Obsession remains unaffected by this penalty.
You can only be obsessed with one Survivor at a time."

Survivors cleansing or blessing any Totem suffer from the Oblivious Status Effect for 35/40/45 seconds.
After cleansing or blessing a Hex Totem, the Auras of all Survivors are revealed to you for 15 seconds.
The Hex effects persist until its Hex Totem is cleansed.

When you hook a Survivor, Dead Mans Switch activates for the next 30 seconds.

While activated, any Survivor that stops repairing a generator before it is fully repaired causes The Entity to block the generator until Dead Mans Switchs effect ends.

Affected generators are highlighted by a white aura.
