When a Survivor heals another  Survivor for one health state at least 32 meters away from the Killer, the Survivor performing the healing action will scream, revealing their location and activating Deathbound for the next 60 seconds.  During that time, the Survivor will suffer from the Oblivious status effect when further than 8 meters away from the healed Survivor.

Oblivious prevents the Survivors from hearing or being affected by the Killers Terror Radious.

After hooking a Survivor, Pop Goes the Weasel activates for the next 35/40/45 seconds:

Performing the Damage Generator Action on a Generator instantly regresses it by -20 percent of its current Progression, after which normal Regression applies.

The Auras of Breakable Walls, Pallets, and Windows are revealed to you within 24/28/32 meters.

The Auras of Survivors attempting to blind you with a Flashlight are revealed to you for 6/8/10 seconds.
Lightborn grants immunity from being blinded by Flashlights, Firecrackers, Flashbangs, or Blast Mines.

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.

Performing the Damage Generator Action on a Generator activates Trail of Torment:

Grants the Undetectable Status Effect until the Generator stops regressing or a Survivor is damaged by any means.
The Aura of the damaged Generator is revealed to all Survivors in yellow.
Trail of Torment has a cool-down of 80/70/60
