Say there are 6 players (one of whom is yourself), you are Blue Dragon and estimate there are 3 Unseen. You know that if any player is accused by at least 3 people (none of whom is yourself), the accused person is innocent, since otherwise an Unseen would be voting up a fellow Unseen member.
Can someone write a formula for calculating the number of accusations by non-neutral, non-starting king players required to prove the defendant’s innocence, given the total number of players, and the total number of evil faction members?
