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.

While you are chasing the Obsession, this perk activates.

Damaging generators and breaking walls or pallets gives you a 5percent Haste Status for 10 seconds.

 Whenever you hit the Survivor with the total most time in chase with a basic attack, they become the obsession.

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

The Auras of Scourge Hooks are revealed to you in white.
Each time a Survivor is hooked on a Scourge Hook, the following effect applies whenever you are farther than 24 metres from the hooked Survivor:
Accelerates the Sacrifice Process by 10/15/20 percent.

Your base Terror Radius is increased by 8 meters.

Whenever you are outside of a Chase, your Terror Radius is reduced by 16 metres while your Field of View is increased by 3/5/10 °.
Field of View gains do not stack.
