Concept by Justin Forman
One of the goals of the Window is to free the actors from bookkeeping minor details. Who in their right mind wants to bother with encumbrance, hit points, or damage dice when there's roleplaying to be done? All that these do is add up to more number oriented thinking, and that goes against the philosophy of the first precept.
That being said, there is little in this world which is more number oriented than money, and while first generation roleplaying has a healthy tradition of recording cash down to the last copper piece, some actors would rather not bother at all. On the same token, in some settings it is important to have an idea of how wealthy a character is.
To deal with this problem, the Storyteller can choose to define an inherent trait called wealth. If a situation comes up in the story when limits in a character's monetary resources become a concern, the Storyteller could ask for a wealth roll. A success means that the character has the money available for the task, while a failure means he's short. Like always, this rule is one that requires intelligent interpretation by everyone involved.
