Tail

You are able to track and tail targets with expert skill. When you activate this Ability choose a target within Range. You are now able to follow that target without being seen by them.

You may safely get within Close Range of the target whilst tailing them. If you attack them or take a significant action that would get you noticed then they spot you, otherwise you follow them to their destination. You can also eavesdrop on any conversations they are having and see any activity they are engaging in.
