I dont know if it actually picks up all creatures, ive only ever seen it work with humans (but i did have 0%).
But if it does, then you could easily see if a spawn is around within 2 screens of you or something.... Problem is though, if u use it and dont see it, and leave, it may be there, just out of range a tiny bit.. so personally i wouldnt risk it :\ wont do any harm to walk a few more tiles
tracking is like detection depending on your amount of skill you can found steeds in a large area
academy rangers have a lessons of this but only for academy ppl
