While standing in a Locker for 3 seconds, Head On activates:

When performing a rushed action to leave a Locker, stun the Killer for 3 seconds if they are within range.
Head On causes the Exhausted Status Effect for 60/50/40 seconds.

Head On cannot be used when Exhausted or when you have accrued Idle Crows.

You start the trial with 3 Tokens.
Whenever the Killer attempts to read your Aura, Distortion activates and 1 Token is consumed:

Your Aura will not be shown to the Killer and you will not leave any Scratch Marks for the next 6/8/10 seconds.
Every 30 seconds you are within the Killer's Terror Radius, Distortion gains back 1 Token.

Distortion does not activate when you are in the Dying State.

Distortion cannot accumulate more Tokens than its initial count.

After triggering your third Protection Hit, Mettle of Man activates:

While injured, Mettle of Man shields you from going down the next time you take damage.

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