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.

Putting a Survivor into the Dying State with your Basic Attack blocks their Aura from being revealed to any Survivor, who is farther than 32/24/16 metres away from them.

For the next 15 seconds, the following effects apply to the dying Survivor:

Reduces their Field of View and causes them to be deafened.
Suffers from the Blindness Status Effect.
Reduces the Crawling speed by -50 percent.
Reduces the Recovery speed by -25 percent.

After hooking a Survivor, THWACK! activates:

The next time you break a Breakable Wall or a Pallet, all Survivors within 28/30/32 meters of your location will scream and reveal their Aura for 4 seconds.

While carrying a Survivor, increase your Carrying Movement speed by 6/12/18percent.  Increases your Terror Radius by 12 meters.

Each injured, dying, or hooked Survivor afflicts Survivors with a stack-able 1/1.5/2 percent Action Speed penalty to Repairing, Sabotaging, and Cleansing, up to a maximum of 4/6/8 percent.
Increases the Action Speed penalty by a further 12 percent, if there are 4 Survivors, who are either injured, dying, or hooked at the same time.

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.
