Notes
Ectoplasmic Residue is part of the detective side of Ghostbusters. It is not there to hit back. It is there to tell you a space has been touched, crossed, or disturbed by something paranormal before the next fight starts.
Contact Protocol
This is another scan-and-read entry, not a brawl. Use it to follow the paranormal trail and make sense of the room before the next real encounter opens up.
