By means of this spell the illusionist misdirects the information from a detection-type spell, i.e. detect charm, detect evil, detect invisibility, detect lie, detect magic, and detect snares & pits. While the detection spell functions, the information it reveals will indicate the wrong area, creature, or the opposite of the truth with respect to detect evil or detect lie. The illusionist directs the spell effect upon the creature or item which is the object of the detection spell. If the caster of the detection-type spell fails his or her saving throw, the misdirection takes place.
