Performing the Damage Generator Action on a Generator applies Overcharge:

The next Survivor interacting with that Generator is faced with a difficult Skill Check.
Failing the Skill Check results in an immediate Progression loss of 3/4/5 percent.
Succeeding the Skill Check grants no bonus Progression, but prevents the Generator from exploding.
After Overcharge is applied to a Generator, the following effect applies:

Increases the Regression speed from 75 percent to 200 percent over the next 30 seconds.

Once the Exit Gates are powered, if there is still a Dull Totem remaining on the Map, Hex: No One Escapes Death activates and lights it:

Increases your Movement speed by 2/3/4 percent.
Survivors suffer from a permanent Exposed Status Effect.
Hex: No One Escapes Death remains inactive if no Dull Totems are available.

Once the Status Effect is revealed to Survivors, Hex: No One Escapes Death reveals the Aura of its Hex Totem to all Survivors within 4 meters and gradually expands that range to 24 meters over the course of 30 seconds.

The Hex effects persist until its Hex Totem is cleansed.

Injuring a Survivor by any means lights a Dull Totem, activating the Hex.

While the Hex is active, all other Survivors outside of your Terror Radius will scream every 25 seconds, revealing their positions and auras for 2 seconds.

If the Hex totem is cleansed, this perk is permanently disabled.

Putting a Survivor into the Dying State with your Basic Attack blocks their Aura from being revealed to any Survivor, who is farther than 32/24/16 metres away from them.

For the next 15 seconds, the following effects apply to the dying Survivor:

Reduces their Field of View and causes them to be deafened.
Suffers from the Blindness Status Effect.
Reduces the Crawling speed by -50 percent.
Reduces the Recovery speed by -25 percent.
