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.

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.

Hoarder triggers a Loud Noise Notification for 4 seconds, whenever a Survivor performs any of the following actions within 32/48/64 meters of your location:

Unlocks a Chest.
Picks up any Item, including Limited Items.
Hoarder spawns 2 additional chests in the Trial.

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.
