Life Detection was a specific Ta-Ree incantation that could be used by Ascendants who lived on the world of Kathol. This incantation allowed the user to sense living organisms that were not detectable through ordinary means. Upon casting, the spell enabled the Ascendant to pinpoint the location of all sapient creatures within a ten meter radius. Ascendants with greater skill could also discern whether the individuals had Ta-Ree powers or sensitivity to the Force. Due to its origins on Kathol, the use of this life detection spell on Humans and Near-Human species caused a unique adverse reaction: nausea in the targets.
