Tracking people based on their trail.
Ability Score(s): Reason
Usage: Tracking creatures based on the trail they leave in the ground. Doing so can be made more or less challenging based on the environment. Typically tracking a single set of footprints requires a DC 20 check.
After it has snowed or rained decreases the DC by 10, however if attempting to do so during a snow or rain storm only decreases the DC by 5. Marshes increase the DC by 5, dry fields increase the DC by 10, and finally tracking during a sandstorm, blizzard, or other natural disaster increases the DC by 40.
Tracking additional sets of footprints increases the DC by 10 for each additional pair of footprints being tracked.
