False vision

False vision was an illusion spell that fooled scrying with an illusion.

Effect
The caster and all he desired within the area of the spell became undetectable to scrying (whether by spell or magic device). Furthermore, if the caster was aware of an attempt to scry, he could create whatever image he desired, including sight and sound, according to the medium of the scrying method. To do this, he had to concentrate on the figment he was creating. Once concentration was broken, no further images could be created, although the area remained undetectable for the duration of the spell.

Material component
The ground dust of a jade worth at least 250 gp, which was sprinkled into the air when the spell was cast.
