Characters with this skill can follow any trail made by animals or travellers; a faint or difficult trail may require an Int test, at the gamesmaster's discretion. The trail can be followed without the tracker becoming slowed down. From hoof impresssions, the state of fires and other trail features, characters can Estimate the distance between themselves and their quarry (either in days or distance) with a +10% modifier. Trackers may also add a +10% modifier to tests to Estimate the numbers of quarry and, in some cases, their racial types. They can identify animal species from their droppings where present.
