Μελαν Και Σφαιρικον Δεσμωτηριον (黒き牢球, Black Sphere Prison) is a capture spell in which the target is first covered in asphalt to restrict movement, then sealed within a shrinking spherical bounded field. This spell is powerful enough to trap dragons and other massive, spiritually powerful beings. Without special means of sustaining life, the target will asphyxiate once the asphalt hardens.
