Performing the Damage Generator Action on a Generator activates Trail of Torment:

Grants the Undetectable Status Effect until the Generator stops regressing or a Survivor is damaged by any means.
The Aura of the damaged Generator is revealed to all Survivors in yellow.
Trail of Torment has a cool-down of 80/70/60

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 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.

For each Totem remaining in the environment, Hex: Thrill of the Hunt gains 1 Token.

Survivors suffer from a stack-able 8/9/10 percent Action Speed penalty per Token to Cleansing and Blessing, up to a maximum of 40/45/50 percent.
Grants a stack-able 10 percent bonus Bloodpoints for actions in the Hunter Category per Token, up to a maximum of 50 percent.
The Hex effects persist until its Hex Totem is cleansed.

You become obsesses with one Survivor.  When your obsession is hooked, Furtive Chase receives a token, up to a maximum of 4 tokens.

Each token decreases your Terror Radius by 4 meters while in a chase.

When a Survivor rescues the Obsession from a hook, the rescuer becomes the Obsession.

Each injured, dying, or hooked Survivor afflicts Survivors with a stack-able 1/1.5/2 percent Action Speed penalty to Repairing, Sabotaging, and Cleansing, up to a maximum of 4/6/8 percent.
Increases the Action Speed penalty by a further 12 percent, if there are 4 Survivors, who are either injured, dying, or hooked at the same time.
