A Yapi is shown employing shadowstrike on a Krakai adversary. Shadowstrike represented a specific Ta-Ree incantation that could be utilized by Ascendants located on the planetary body of Kathol. This particular spell empowered the user to inflict strikes upon a designated target without the need for any physical contact. If the target wasn't Force-sensitive, avoiding these strikes proved impossible.
To successfully perform the shadowstrike spell, Ascendants needed prior knowledge of both the psychokinesis and sense life incantations.
