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.

Gain a notification when a Survivor begins sabotaging a hook.

While carrying a Survivor, see the aura of any survivor within 6 meters of a hook.

The Auras of Survivors within 2/3/4 meters of any Dull Totem are revealed to you.

When another Perks Hex Totem is cleansed or blessed, its Hex is transferred to the Hex: Undying Totem, including any accumulated Tokens, disabling Hex: Undying instead.
The Hex effects persist until its Hex Totem is cleansed.

3 generators located furthest from you are blocked by The Entity for 120 seconds at the start of the trial.  Survivors cannot repair these generators for the duration.  Affected generators are highlighted by a white aura.

As soon as an exit gate is opened, Blood Warden is activated.  The auras of any Survivors located within Exit areas are revealed to you.  Once per match, hooking a Survivor while Blood Warden is active calls upon The Entity to block both Exits for all Survivors for 60 seconds.
