You become obsessed with one Survivor.  When the Obsession loses a health state, your Terror Radius transfers to the Obsession for 30 seconds, and its radius is set to 32 meters.

You are granted the Undetectable status effect for the duration.

The Survivor with the transferred Terror Radius is also considered to be "inside the Terror Radius" for other purposes.

The Killer can only be obsessed with one Survivor at a time.  Undetectable hides the Killers aura, Terror Radius, and Red Stain.

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.

When carrying a Survivor, Starstruck activates:

Survivors suffer from the Exposed Status Effect while in your Terror Radius.
The Status Effect lingers for 26/28/30 seconds after leaving your Terror Radius.
After hooking or dropping the carried Survivor, Starstruck deactivates:

The Status Effect persists for 26/28/30 seconds for any Survivor inside your Terror Radius at that moment.
Starstruck has a cool-down of 60 seconds once the Survivor is no longer being carried.

Whenever you are stunned by a Survivor, that Survivor suffers from the Exposed Status Effect for 10/15/20 seconds.

Hubris has a cool-down of 20 seconds

Injuring a Survivor will call upon The Entity to block pallets from being pulled down within a 32 meter radius of the Survivor location for 15 seconds.

The Hex effects persist as long as the related Hex Totem is standing.

Any Survivor repairing a generator suffers from the Blindness and Exhausted status effect.  If the Survivor is already Exhausted, their status effects timer will be paused.

Both status effects linger for 5 seconds after stopping repairs.
