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.

Survivors cleansing or blessing any Totem suffer from the Oblivious Status Effect for 35/40/45 seconds.
After cleansing or blessing a Hex Totem, the Auras of all Survivors are revealed to you for 15 seconds.
The Hex effects persist until its Hex Totem is cleansed.

Any generator within a range of 128 meters that is being repaired by two or more Survivors is marked by a yellow aura.  When the generator is first highlighted, Discordance triggers a loud noise notification on the generator.  After the generator is no longer within range or is no longer being repaired by two or more Survivors, the aura remains for another 4 seconds.

The Auras of regressing Generators are highlighted in white.

If the Regression progress is interrupted on a Generator, its Aura will be highlighted in yellow for 8/12/16 seconds.
Surveillance increases the audible range of Survivors Generator-repairing noises by 8 meters.

The Auras of Breakable Walls, Pallets, and Windows are revealed to you within 24/28/32 meters.

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.
