Sphere of the Infinite Agonies. Every second a lifetime.
Winifred Burkle[src]

The Sphere of the Infinite Agonies was a binding spell that inflicted extreme pain to the victim, who experienced each second as if it were "a lifetime". The spell only required to be read and even a spellcaster without experience like Winifred Burkle could perform it.

Fred and Angel threatened the demon Skip to submit him to the Sphere when he was imprisoned in the Sand of the Red Palm for questioning about the being that had taken possession of Cordelia Chase.
