Although not often, this skill can be helpful in specific situations: it comes in handy in areas with many stealthed creatures and in situations at which you have to find a particular stealthed mob. An advantage is that it works on all nearby fellowship members at once. An example where this skill is useful is the tracking of Guldur Fell-hunters in Barad Guldur. Sign of Power: Vigilance makes that people are more likely to notice these. The skill is also of vital importance in the Ettenmoors, where it reveals Warg Stalkers that are about to sneak upon you.
The animation of Sign of Power: Vigilance shows the word tirith, written in Tengwar. This can be translated as 'vigilance'.
