Summon Oni

Summon Oni is a mastery level 4 maho spell which teleports the most powerful oni within the range of the spell to a location choosen by the caster. It does not grant the caster control of the oni however, and the oni will not be pleased at having been transported from where it was. The oni may be unaware of the caster, if the caster is lucky.
