If killed, can still chat with the living each day, but cannot vote on lynch. Cannot see meetings like normal dead people can. Cannot chat with other dead people.
It is a conversational town-sided role and doesn't convert. Basically, it dies and can still talk to the town, and cannot cheat by seeing who shows up in the night meetings.
You should make it a conversion role, and give it something to balance it out. Maybe make it so that it can't convert a role that visited somebody else that night (slow zombies)
I suppose the zombie that starts out wouldn't have much reason to talk to the living after it "dies" aside from helping the remaining zombies win, but converted roles might still win if they meet the win conditions of their original role? Some kind of 'memories of life' type effect?
I just don't think there's enough to go on with it's current description.
maybe, you can make him a third party, that can only die by a gunshot at night, and he converts... But your idea is quite good already. Keep up the good work.
