This power seems to be messed up. I used it on an individual and it told me they went south. So I go a couple south (on a road with only north and south with no branches off between) and it tells me they went north. I go north, it tells me they went south. I finally decided to try it in a location where I know this person would never go, i.e. the Tribunal Spire. Low and behold it was giving me directions. I went one down from the executioner, it said they went north. I go north and back to the original position, and now it says they went up. I go up and it says they went down, although its impossible they could have been there. When I do it multiple times in one place it gives me the same direction, but if I leave and return to that one place, it will give me a new and seemingly random directly.

Thanks.

This is by design...

You are trying to follow the blood tracks, but you are not going to get it right every single time (as your skill % shows).
