Playing Bamberg with friends

About Bamberg, from BoardGameGeek:

Bamberg is a social deduction game based on the witch trials of 17th century Europe. At the beginning of the game, you will receive a secret role which can be Child, Villager, Witch or Familiar. Children and Villagers belong to The Town team, whereas Witches and Familiars belong to The Coven team. At first, you will not know who is on your team and who is against you, but as the game progresses, the event cards will help you discover more about each player's identity. At the end of each round, players will vote anonymously for whom to burn at the stake, and the player that receives most votes dies. Only Children and Witches reveal their role when they die. If all Witches die, The Town wins the game. If all Children die, The Coven wins the game. -description from the rulebook
