How to obtain knowledge out of ghosts ?

[Camo]

Do you know how to obtain knowledge out of ghosts? They cannot be placed in the Analysis Room so I'm not sure what to do with them.

I’ve been able to place my ghosts in the deconstructor. What’s happening when you try it?

[Jaggid Edje]

In the analysis room. You are mistaken in thinking they can't be placed there; they can.

[Camo]

Oh weird! It says "Can't place Gentlefolk in Analysis Room as it's unique".

[GhostWolfe]

Unique ghosts are already at max knowledge, and you only get one of them, so deconstructing them wouldn’t be a good idea.

Mh, this ghost is at 1/3 knowledge. Maybe it's because it's the first one of this campaign (Fenton Martini)? Thank you for your answers in any case!

You cannot analyze the first ghost during campaign but you can once you get a 2nd and you cannot analyze unique ghosts
