You become obsessed with one Survivor.  When the Obsession loses a health state, your Terror Radius transfers to the Obsession for 30 seconds, and its radius is set to 32 meters.

You are granted the Undetectable status effect for the duration.

The Survivor with the transferred Terror Radius is also considered to be "inside the Terror Radius" for other purposes.

The Killer can only be obsessed with one Survivor at a time.  Undetectable hides the Killers aura, Terror Radius, and Red Stain.

Any Survivor who blinds you or stuns you using a Pallet becomes the Obsession.
Anytime your Obsession switches to another Survivor by any means, that Survivor then suffers from the Oblivious Status Effect for 40/50/60 seconds and their Aura is revealed to you for 4 seconds.
You can only be obsessed with one Survivor at a time.

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

The Auras of Scourge Hooks are revealed to you in white.
Each time a Survivor is hooked on a Scourge Hook, the following effect applies whenever you are farther than 24 metres from the hooked Survivor:
Accelerates the Sacrifice Process by 10/15/20 percent.

Injuring a Survivor will call upon The Entity to block pallets from being pulled down within a 32 meter radius of the Survivor location for 15 seconds.

The Hex effects persist as long as the related Hex Totem is standing.

After damaging a generator this perk becomes active for 60 seconds.

The generator regresses at 200percent of the normal regression speed and you can se its aura in yellow.

Each time a Survivor completes a good Skill Check on a generator affected by this perk, you receive a loud noise notification.

3 seconds after injuring a Survivor by any means, Dissolution activates for 20 seconds.  While Dissolution is active, if a Survivor fast vaults over a pallet inside of your Terror Radius, The Entity will break the pallet at the end of the vault, and Dissolution deactivates.
