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.

You become obsesses with one Survivor.  When your obsession is hooked, Furtive Chase receives a token, up to a maximum of 4 tokens.

Each token decreases your Terror Radius by 4 meters while in a chase.

When a Survivor rescues the Obsession from a hook, the rescuer becomes the Obsession.

As soon as an exit gate is opened, Blood Warden is activated.  The auras of any Survivors located within Exit areas are revealed to you.  Once per match, hooking a Survivor while Blood Warden is active calls upon The Entity to block both Exits for all Survivors for 60 seconds.

While you are chasing the Obsession, this perk activates.

Damaging generators and breaking walls or pallets gives you a 5percent Haste Status for 10 seconds.

 Whenever you hit the Survivor with the total most time in chase with a basic attack, they become the obsession.
