I'd like to clarify something regarding possessing a player's body. When the Host takes control of a player's body, they can still use the skills of that role, not just kill with it and control the voice. But there's also a downside! If Ann uses her ultimate ability on a player whose body has been possessed by the Host, the ghost dies, and the victim remains alive. This is something like an expulsion, but with a fatal outcome for the ghost. I was hesitant, but I think this will be more correct...
If you have any more questions, you can ask them here or in a private message, and then I will write the answers in the thread.
