A unique role is a role that is limited to 1 player per game. For most of them, there can never be two in one game; the Godfather and Mafioso can be inherited, but even for those, only one of each can be alive at once. Currently, there are seven unique roles. Mainly, unique roles only consist of support and killing roles. There are two Town Supports that are unique, two Town Killing, two Mafia Killing, and one Neutral Killing.
