Sowing Rumors

Downtime Activity: Sowing Rumors DMG p131 Swaying public opinion can be an effective way to bring down a villain or elevate a friend. Spreading rumors is an efficient, if underhanded, way to accomplish that goal. Well-placed rumors can increase the subject's standing in a community or embroil someone in scandal. A rumor needs to be simple, concrete, and hard to disprove. An effective rumor also has to be believable, playing off what people want to believe about the person in question.
  Sowing a rumor about an individual or organization requires a number of days depending on the size of the community, as shown in the Sowing Rumors table. In a town or city, the time spent must be continuous. If the character spreads a rumor for ten days, disappears on an adventure for another few days and then returns, the rumor fades away without the benefit of constant repetition.

Settlement Size Time Required
Village 2d6 days
Town 4d6 days
City 6d6 days
The character must spend 1 gp per day to cover the cost of drinks, social appearances, and the like. At the end of the time spent sowing the rumor, the character must make a DC 15 Charisma (Deception or Persuasion) check. If the check succeeds, the community's prevailing attitude toward the subject shifts one step toward friendly or hostile, as the character wishes. If the check fails, the rumor gains no traction, and further attempts to propagate it fail.
  Shifting a community's general attitude toward a person or organization doesn't affect everyone in the community. Individuals might hold to their own opinions, particularly if they have personal experience in dealing with the subject of the rumors.
