After a Survivor loses a health state, Gearhead activates.

While Gearhead is active, the next time a Survivor completes a Great Skill Check while repairing, the perk deactivates and their aura is revealed to you for 10 seconds.

Unlocks potential in ones aura reading ability.  Each time a generator is fully repaired, Survivors within 16 meters of the completed generator will be revealed for 5 seconds.  When the last generator is fully repaired, all the survivors auras are revealed for 10 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.

Survivors within your Terror Radius suffer from inefficiency:

When using an Item, its Depletion rate is increased by 80/90/100 percent.

Injuring a Survivor by any means lights a Dull Totem, activating the Hex.

While the Hex is active, all other Survivors outside of your Terror Radius will scream every 25 seconds, revealing their positions and auras for 2 seconds.

If the Hex totem is cleansed, this perk is permanently disabled.

Instead of snuffing Boon Totems you destroy them.
Destroying a Boon Totem this way reveals the Auras of all Survivors that were within its range at that moment for 6/7/8 seconds.
