so you buy the skill animal tracking and you get a skill toggle much like tracking criminal acts.
when you turn on the toggle, if your perception and exploration is good enough you will see footprints on the ground, they will essentially be like scents, but spawn like herbs, so different types of footprints look different and take different values of skill to see. you right click the footprints, get an option examine, which is basically "pick up" and when you examine the footprints you get a tracking object in your inventory.
once you have a tracking object in your inventory, you just right click it and it will point to the closest animal of that type if any were close just like tracking a scent of a criminal act does.
now i dont know if this will work that well if the map isn't loaded with animals etc, but oh well.
donno if people would ever use this, iam assuming they might if it was a bears footprints, but not if it was just a deer. Their needs to be more strong animals with worth while loot. or a bonus for killing an tracked animal. as opposed to one without a tracking object.
