The Auras of Survivors, who are healing or being healed, are revealed to you when they are within a range of 20/24/28 meters.

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.

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.

Gain a notification when a Survivor begins sabotaging a hook.

While carrying a Survivor, see the aura of any survivor within 6 meters of a hook.

For each Survivor you hook for the first time, No Way Out gains 1 Token.
Once the Exit Gates have been powered, No Way Out activates:

When a Survivor interacts with an Exit Gate Switch, you receive a Loud Noise Notification and The Entity blocks both Exit Gate Switches for 12 seconds and an additional 6/9/12 seconds per Token in your possession, up to a combined maximum of 36/48/60 seconds.

You hear the sporadic whispers of the Entity whenever at least one Survivor is within 48/40/32 meters of your location.
