★Zahhak (ザッハーク Zahhāku) is a Dark Magic scroll that only appears in TearRing Saga: Utna Heroes Saga. The personal spell of Gwenchaos, it calls upon the soul of the nefarious Azhi Dahaka to not just inflict copious amounts of damage onto a selected enemy unit, but also seal his/her attacks at the same time, rendering him/her incapacitated and unable to retaliate.
Enemy-only; Seals the attacks of a selected enemy unit.
The name of this spell is derived from the evil figure of the same name in Iranian mythology, who is also known as Aži Dahāka in the texts of the Avesta and Dahāg/Bēvar-Asp in Middle Persian. Zahhak is described as a monster with three mouths, six eyes, and three heads (presumably meaning three heads with one mouth and two eyes each), cunning, strong and demonic. But in other respects, Aži Dahāka possesses human qualities, and is never a mere animal. In a post-Avestan Zoroastrian text, the Dēnkard, Aži Dahāka is possessed of all possible sins and evil counsels, the opposite of the good king Jam. The name Dahāg (Dahāka) is punningly interpreted as meaning "having ten (dah) sins." His mother is Wadag (or Ōdag), herself described as a great sinner, who committed incest with her son. (Source)
