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 Survivor suffers from the Hemorrhage and Mangled Status Effects until healed.
Upon being healed, the Survivor suffers from a 10/13/16 percent Action Speed penalty to Healing and Repairing until they are injured again.

Survivors within your Terror Radius suffer from inefficiency:

When using an Item, its Depletion rate is increased by 80/90/100 percent.

3 seconds after injuring a Survivor by any means, Dissolution activates for 20 seconds.  While Dissolution is active, if a Survivor fast vaults over a pallet inside of your Terror Radius, The Entity will break the pallet at the end of the vault, and Dissolution deactivates.

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.

After damaging a generator, for the next 30 seconds, the first Survivor that interacts with it will scream, revealing their location for 4 seconds, and becoming afflicted with the Exposed status effect for 60 seconds.

Dragons Grip has a cooldown of 80 seconds.

Exposed Survivors will be downed by basic attacks even if uninjured.

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.
