I decided to go with the following build:

Object of Obsession - Look for the other survivors and wave and point for the killer.

Better Together - Work on a generator to lure other survivors to me so I can point them out to the killer.

Fixated - Because as the Entity/Killer, I should be able to see scratch marks.

Calm Spirit - The crows are the eyes of the Entity, and the powers bestowed upong the killers come from the Entity. So the world and abilities will not work against Nea.

Object of obsession is really the ONLY survivor you can use to actively help the killer, but when it's combo'd with perks that lure survivors to you it can be a lot more helpful.

I considered using perks like bond or other perks to see where other survivors are, but I went with Fixated and Calm Spirit to give some more thematic feel to the build and make it seem more like the Entity was walking among the survivors.
