While Dwarves get this skill by virtue of their genetics, other races can approximate the Dwarfish ability by virtue of careful training. On a successful proficiency check, the character with Direction Sense will know the direction he or she is facing, even if there is no compass, stars, or sun available. By virtue of this skill, the character also gains a +1 to Navigation and a +1 to Cartography. If a Construct takes this skill, the entity gains a +2 bonus in the absence of strong magnetic fields, but takes a –4 penalty in the presence of magnetic distortions.
Critical Success: The character has an uncanny sense of where he currently is and where he is going.
Critical Failure: On a simple failure, the character simply cannot tell the direction and is forced to guess. On a critical failure, the character will think he knows the correct direction, but will in fact be off by 90, 120, or 180 degrees (GM rolls a 1d3 for this determination).
