Grants 40/45/50 percent of your missing Healing Progression to your Health Bar.

After being unhooked or unhooking yourself, Decisive Strike activates for the next 40/50/60 seconds:

When being grabbed or picked up by the Killer, succeed a Skill Check to automatically escape their grasp, stunning them for 3 seconds.
Successfully stunning the Killer will disable Decisive Strike for the remainder of the Trial and result in you becoming the Obsession.
While Decisive Strike is active, performing Conspicuous Actions will deactivate it for the remainder of the Trial.

Decisive Strike deactivates once the Exit Gates are powered.

The Killer can only be obsessed with Survivor at a time.

This effect lingers for 15 seconds when leaving Leaders range.
Survivors can only be affected by one instance of Leader at a time.
