Navigator's tools

These precision instruments allow you to relate your position to the position of the stars. So long as you are on the Material Plane and can freely observe the stars, once per night you can make a navigator’s tools check. On a result of 15–19 you learn one of the following pieces of information, or two pieces of information on a result of 20 or higher:

• The approximate time of year.
• Your approximate distance from the equator (assuming the world has a known axis).
• Your approximate distance from the place you last made this check.
• Your current distance from a major landmark and the approximate amount of time it will take to reach it.
