Tracker

You are adept at following prey... animal or human.
Footprints, hair, blood, broken twigs, smashed grass... they are for you to find and read.
They tell you a story of what happened there.
This is not something usually allowed to be done with the Survival skill alone, since it requires special knowledge, training or experience. Now you can do it.
You can roll Perception & Survival to find and follow a track in the wilderness, and to interpret the clues.
You can roll Smarts & Survival to try to cover your tracks, and the tracks from the people travelling with you.
You also get a +2 modifier to the results of these rolls.
On a success you get the following basic information:

• Species (if you know it, otherwise just "clawed predator" or "big hoofed animal").
• Number of individuals.
• Direction.

For each raise, the GM will give you one more piece of info from the list below, depending on the nature of the clue:

• Approximate time since the clue was left.
• Size and Weight, and perhaps sex (if it makes sense).
• Peculiarities and velocity (limping, bleeding, dragging something, very old shoes, sneaking, walking, jogging, running).
• What happened in the scene.
• Authenticity of the clue... misleading clues are a good way to lose a tail.
• Possible destinations.

If you fail you lose the trail, and on a critical failure, you misinterpret the clues with dire consequences.

Your rolls suffer difficulty modifiers:

• Hard featureless ground (solid rock, desert crust, ice): +2
• Rainy or snowy weather: +2
• Darkness.
• Intentional effort to cover the tracks: -4
• Soft ground (mud, snow): -2
• Wounded prey: -1
