Each time the Survivors complete repairs on a generator, Fire Up grows in power.

For each generator completed, gain a 4percent stackable buff that grants a speed bonus to picking up, dropping, vaulting, damaging generators, and breaking pallets and breakable walls for the remainder of the trial.

After breaking 4/3/2 Pallets, Spirit Fury activates:

The next time you are stunned by a Pallet, The Entity instantly breaks it.
The normal Stun penalty still applies.
Spirit Fury deactivates after applying its effect.

3 generators located furthest from you are blocked by The Entity for 120 seconds at the start of the trial.  Survivors cannot repair these generators for the duration.  Affected generators are highlighted by a white aura.

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.

Performing the Damage Generator Action on a Generator triggers Nowhere to Hide:

The Auras of all Survivors within 24 meters of your position are revealed to you for 3/4/5 seconds.

Any Survivor who blinds you or stuns you using a Pallet becomes the Obsession.
Anytime your Obsession switches to another Survivor by any means, that Survivor then suffers from the Oblivious Status Effect for 40/50/60 seconds and their Aura is revealed to you for 4 seconds.
You can only be obsessed with one Survivor at a time.
