This skill allows a character the ability to follow a trail, left by someone or something passing through the area. A BCS roll must be made at each decision point (anywhere the trail my go in multiple directions or comes across a body of moving water). The older the trail is, the harder it will be to follow. The exact amount of difficulty is left up to the GM. The skill also allows the character the ability to hide his/her trail. A successful BCS while trying to hide the trail will allow the character to make a Wit Group Effect Die roll. The result for the Wit Group Die roll is then used as a negative modifier to someone trying to track the character.
