This skill is required for charting courses across the seas or other empty, featureless areas. Characters with navigation can plot courses by virtue of nautical maps, a compass, or by the sun and stars. This skill has more far-reaching applications than Directional Sense, but it requires equipment and time to use. Characters with navigation also aid in directing the course of a sailing ship.
Critical Success: The navigator is able to plot a very efficient course, subtracting 10% from the travel time.
Critical Fumble: The navigator gets the ship hopelessly lost. A new Navigation check may be tried in a day or if it becomes obvious that the ship is lost.
