The Priest

The Priest is a Villager who can shield one of the other players from Werewolf attacks. On the first night, the Priest chooses who should receive protection. The next attempt to kill the selected player fails. The night after that attempt (or if the protected player is lynched / killed by the Witch, the Hunter, etc), the Priest can choose a different player to shield.

The Priest tilts the balance towards the Villagers, since the chosen player is likely to be a Villager (though he might accidentally shield one of the Werewolves). The Priest can protect the Seer and other important Villager roles as long as he is still alive.

The Priest Variations

 * One per game, publicly reveal your card and throw holy water onto a player. If the target is aligned with the werewolves, he dies. Otherwise, the priest dies.
