I stared playing a character in Curse of the Crimson throne about a month or two back an am playing a charlatan rogue with the Natural Charmer feat and have just hit level 3, so, the million dollar question! What would be some of the best/most comical uses for Rumormonger?
You could try to convince everyone that you're the true heir to the throne and the Arabasti's killed your parents. Bonus points if you chose the Love Lost (Orphaned) Campaign Trait from the Player's Guide.
