Odd question.

[Haruka Zanzamoto]

Can Force Ghosts be limited with a weakness?

I ask simply because they are not under Banned Species as far as I saw. Also, I remember the fight against old Obi-wan in the Ultimate Sith Edition of The Force Unleashed thinking about this.

... Now that I think about it, is this the right place to even ask that?

Force Ghosts cant interact with the physical plane. Thats the weakness.

Any sort of thing that CAN interact with the physical plane and retain a ghostly look?
