Tracker

When you touch someone or something you can magically attach a marker to them that is near undetectable except by certain forms of magic within a range. This tracker can be seen by the user within their given range. They can see this tracker through anything and it will essentially be on their radar so long as it is in range.

The range of your tracker is 1500ft x Player Level.
Even while the tracker is out of range, it is still active, just undetectable.
You can have 2 + ((level) / 3) active trackers at a time.
You can deactivate trackers even if they are out of range.
