Coin of Destiny
A Coin of Destiny can be used to influence either the rules or the story, as long as it creates an interesting narrative. In the spirit of "Wouldn’t it be cool if...". The GM decides whether it fits. Successful and glorious actions are told around campfires and generate Reputation for the Guild.
At the beginning of each session, every player may flip a coin. On heads, they receive one Coin of Destiny. It expires at the end of the session. If a player has no Coin, they may ask another player for theirs – or beg the GM for one.
