At the start of the Trial, 4 random Hooks are changed into Scourge Hooks:

The Auras of Scourge Hooks are revealed to you in white.
Each time a Survivor is unhooked from a Scourge Hook, the following effects apply:

The Auras of all other Survivors are revealed for 5/6/7 seconds.

The Aura of a Survivor entering the Basement when you are at least 32 meters away is revealed to you for 3 seconds.
Territorial Imperative has a cool-down of 30/25/20 seconds.

Your basic attacks make Survivors drop their item on impact.  While on the ground, it takes up to 90 seconds for the item to lose all of its charges if it is not picked up.  Reveal items on the ground within 32 meters with a white aura.  The aura will slowly fade to red until the item is empty of charges.

Survivors repairing or healing within your Terror Radius suffer from the following effects:

Increases the Trigger odds of Skill Check by 10 percent.
Decreases the Success zone of Skill Checks by 40/50/60 percent.

Each time the Survivors complete repairs on a generator, Fire Up grows in power.

For each generator completed, gain a 4percent stackable buff that grants a speed bonus to picking up, dropping, vaulting, damaging generators, and breaking pallets and breakable walls for the remainder of the trial.

Instead of snuffing Boon Totems you destroy them.
Destroying a Boon Totem this way reveals the Auras of all Survivors that were within its range at that moment for 6/7/8 seconds.
