Pallida Mors

Pallida Mors (パリダ・モルス Parida Morusu, lit. Pale Death in Latin) is the a very powerful spell that Shiori Momono uses in the 11eyes series, particularly in 11eyes CrossOver. According to Shuu Amami, the spell is so powerful that it pulverizes the atoms in the area, which forces a massive energy release and turns into mini nuclear explosion, inflicting heavy damage to the target. In the final battle of the Hollow Mirror Field scenario, Kanae Kuroshida was rendered useless despite her overwhelmingly magical power because of this spell.
