As more of your friends fall to the Killer, you become shrouded in isolation and the Killer's aura-reading abilities towards you are disrupted.
Every time a fellow Survivor is killed or sacrificed, gain a token. For each token, your aura cannot be read by The Killer within a max range of 20/22/24 meters.
When you're the last Survivor alive:
Gain 75% action speed when repairing generators.
Gain 50% action speed while opening an exit gate or the Hatch.
Increases your chances of being The Killer's Obsession.
