You become obsessed with one Survivor.
Each time you hit a Survivor other than your Obsession with a Basic Attack, Save the Best for Last gains 1 Token, up to a maximum of 8 Tokens:

Gain a stack-able 5 percent Cool-down reduction on successful attacks per Token, up to a maximum of 40 percent.
Each time you hit your Obsession with a Basic Attack, Save the Best for Last loses 4/3/2 Tokens.

When the Obsession is sacrificed or killed, you can neither gain nor lose any more Tokens.
You can only be obsessed with one Survivor at a time.

After damaging a generator, its aura is highlighted in yellow.

Whenever a Survivor enters the dying state, every affected generator explodes, losing 10percent worth of progress, and starts to regress.

Any Survivor repairing a generator when it explodes will scream and reveal their aura for 12 seconds.

Eruption has a cooldown of 30 seconds.

While carrying a Survivor, you suffer no cool-down on missed attacks.
Successfully hitting a Survivor will pause the carried Survivors Wiggling Progression for 2/3/4 seconds.

You see the Auras of cleansed Totems.
You can perform a ritual on a cleansed Totem to resurrect it as a Rekindled Totem.
For each Rekindled Totem active at the same time, Hex: Pentimento gains an additional effect:

1 Totem: Decreases all Survivors Repair speed by 20/25/30 percent.
2 Totems: Decreases all Survivors Healing speed by 20/25/30 percent.
3 Totems: Decreases all Survivors Recovery speed from being downed by 20/25/30 percent.
4 Totems: Decreases all Survivors Exit Gate Opening speed by 20/25/30 percent.
5 Totems: All Totems are permanently blocked by The Entity.
When a Rekindled Totem is cleansed, its remains are consumed by The Entity and it cannot be rekindled.

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.

Whenever a Generator is repaired to 70 percent, you benefit from the following effects:
Triggers a Loud Noise Notification for that Generator, revealing its location.
Grants the Undetectable Status Effect for the next 12/14/16 seconds.
Tinkerer can only trigger once per Generator per Trial.
