Escape Artist
Sometimes slipping from bindings, getting out of a tighter space, or breaking free from a grapple is needed by people who are not overly strong. Escape artist allows for a character to wiggle and squeeze out of these situations. If tied up with a rope the escape artist DC is the roll of the Use Rope. If being used to escape a grapple, your escape artist is used to oppose the grapple, instead of your grapple bonus. As for escaping cells, bars, manacles, those are all determined by the DM.
