Any Survivor repairing a generator suffers from the Blindness and Exhausted status effect.  If the Survivor is already Exhausted, their status effects timer will be paused.

Both status effects linger for 5 seconds after stopping repairs.

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.

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.

"Survivors receive a 2/4/6 percent Regression penalty on Failed Skill Checks for Repair and Healing actions.
Hex: Huntress Lullaby grows in power each time you Hook a Survivor, gaining 1 Token, and affecting Repair and Healing Skill Checks:

1 Token: shortens the time between the Warning sound and the Skill check by -14 percent.
2 Tokens: shortens the time between the Warning sound and the Skill check by -28 percent.
3 Tokens: shortens the time between the Warning sound and the Skill check by -42 percent.
4 Tokens: shortens the time between the Warning sound and the Skill check by -56 percent.
5 Tokens: disables the Warning sound.
The Hex effects persist until its Hex Totem is cleansed."
