When this spell is cast, the recipient can move through any type of terrain—mud, snow, dust, etc.—and leave neither footprints nor scent. The area that is passed over radiates magic for 1d6 turns after the affected creature passes. Thus, tracking a person or other creature covered by this spell is impossible by normal means. Of course, intelligent tracking techniques, such as using a spiral search pattern, can result in the trackers picking up the trail at a point where the spell has worn off.
The material component of this spell is a sprig of pine or evergreen, which must be burned and the ashes powdered and scattered when the spell is cast.
