A necromancer is like a Medium for the mafia: he can talks with a seance to his team...also the "Necromancer" could have another options:
- Resurrect one mafia player or NE like jester, witch or exe that gives advantadge to his team.
- Give protection one night to a member of his mafia.
Or maybe is unbalance, only can talk by seance one night to the gf or else.
