Unlocks potential in your Aura-reading ability:
Each time a Generatoris completed, Dark Sense activates:

The Aura of the Killer is revealed to you for 5/7/10 seconds, as soon as they come within 24 metres of you, after which Dark Sense deactivates.

You can see the Scratch Marks of other Survivors.
Whenever another Survivor loses a Health State within 32 metres of you, the Killers Aura is revealed to you for 3/4/5 seconds.

In your countless years in The Fog, you have seen it all, and when you are focused, you can remember most of it too. Succeeding a Great Skill Check while repairing a Generator reveals the Killers Aura to you for 4/5/6 seconds.

You have an uncanny ability to escape the inevitable. While in the Dying State, 50 percent of your Recovery progression is converted into Wiggling progression, up to a maximum of 40/45/50 percent, once you are picked up by the Killer.
