Whenever you cleanse a Totem, Clairvoyance activates:

When empty-handed, press and hold the Ability button to unlock your full Aura-reading potential, allowing you to see the Auras of the Exit Gate Switches, Generators, Hooks, Chests, and the Hatch within 64 metres for 8/9/10 seconds.

Once the Exit Gates are powered, No One Left Behind activates:

Increases your Unhooking and Healing speed by 30/40/50 percent.
Grants 50/75/100 percent bonus Bloodpoints for actions in the Altruism Category.
Grants the unhooked Survivor a 7 percent Haste Status Effect for 10 seconds.
The Auras of all other Survivors are revealed to you.

Increases the Repair speed of any other Survivor by 6/7/8 percent, while you are being chased within 24 metres of the Generator they are currently repairing.

After being unhooked or unhooking yourself, Off the Record activates for the next 60/70/80 seconds:

Prevents your Aura from being revealed to the Killer, if they attempt to read it.
Suppresses Grunts of Pain when injured.
Grants the Endurance Status Effect.
This effect is cancelled prematurely if you perform a Conspicuous Action.
Off the Record deactivates once the Exit Gates are powered.
