CANON-DEMONOLOGY

  uul ... demonology      Perhaps the most likely spell to cause bodily harm
                          to the spellcaster herself, demonology spells
                          are those which attempt to go in the depths of
                          hell or the abyss and attempt (note the word,
                          attempt) to overpower the mind of some foul and
                          evil creature.
