Found this going through some game notes. This was a write up for one of the inspirtation for some of the Laughing Rogue's concepts, and this description was things that guys legend was good at (the italicized bits are key points)
1st Excellency- The Laughing Rogue is quick to act . He is a thief and a charlatan . He has never been afraid to liberate an object or person from another. He seeks to teach lessons and is always up for a game . He shows others their freedom , and often encourages the seed in others, even at cost to himself . Outside of the costume , he is hidden in the crowd . Seeking to go unseen as he moves through the world. In the costume he performs great acts worthy of memory , and is always ready for a challenge .
Much of the Laughing Rogue’s power is derived from his legend, as such this charm may not be used outside of the costume other than to add to larceny rolls. An Infernal may use this charm to add to any roll in which they are breaking established law . It may also aid in any social combat where the Infernal is being deliberately vague . It can also be used to add to any roll that benefits from a specialty from Donning the Mask.
