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.

Gain a notification when a Survivor begins sabotaging a hook.

While carrying a Survivor, see the aura of any survivor within 6 meters of a hook.

Any generator within a range of 128 meters that is being repaired by two or more Survivors is marked by a yellow aura.  When the generator is first highlighted, Discordance triggers a loud noise notification on the generator.  After the generator is no longer within range or is no longer being repaired by two or more Survivors, the aura remains for another 4 seconds.

Your basic attacks make Survivors drop their item on impact.  While on the ground, it takes up to 90 seconds for the item to lose all of its charges if it is not picked up.  Reveal items on the ground within 32 meters with a white aura.  The aura will slowly fade to red until the item is empty of charges.
