After being within the Killer's Terror Radius for 40/35/30 seconds without being chased, Diversion activates:
Press the Active Ability button while crouched and motionless to throw a pebble, creating a distraction for the Killer at a distance of 20 metres from your location.
The distraction consists of the following:

Triggers a Loud Noise Notification.
Creates fake Scratch Marks.
Diversion deactivates after use and resets its timer.

You refuse to fail, even during your darkest hour.
Increases your Action speeds in Healing and Unhooking by 10/12/14 percent for each injured, hooked, or dying Survivor, up to a maximum of 40/48/56 percent.

Unlocks potential in your Aura-reading ability:
For the duration of the Killer carrying another Survivor, you see the Aura of every Hook within 56 metres of the pick-up location:

The Auras of regular Hooks are revealed to you in white.
The Auras of Scourge Hooks are revealed to you in yellow.
Unlocks the ability to sabotage Hooks without needing a Toolbox.

Sabotaging a Hook without a Toolbox takes 2.5 seconds.
The Sabotage action has a cool-down of 90/75/60 seconds.
