Bense said:Jack of all Trades is useless as a background skill, because J-o-T 0 doesn't give you any in-game benefit.
Almost but not quite. There are several careers with events that allow you to increase any existing skill by +1. That would allow JoT 0 to progress to the useful JoT 1. However, I do agree that JoT isn't really appropriate for a background skill. If you want to represent general handiness at a variety of tasks, Trade 0 is a good one to consider.
