Verisimilomancy

Verisimilomancy is the magic of illusion. The first mention of the name for this type of magic in Ghost Story, although  Verisimilomancy has been used several times in the series since Harry first started to mentor Molly.

Description
It is used in making veils and other powerful mind tricks. The only limits of Verisimilomancy is the casters imagination and power. The larger the area effected the more power it takes. These illusions can be both visual and auditory.

Note: Leanansidhe uses the term in Ghost Story when referring to Molly Carpenter's powers of illusion.

Weaknesses

 * The White Council doesn't put much stock in illusion magic because anyone wiht the Sight could nullify it by Seeing right through it.
 * Once the subject that the illusion is directed at suspects illusion, the game is over—they can find the source by simply following footsteps or othe rmeasures.

Known Users

 * Molly Carpenter frequently uses Verisimilomancy to create bright lights, she calls this her one-woman rave spell. She can also create false images of herself or vails to become invisable and even conceal her smell to some degree.


 * Lash uses several illusons on Harry that feel completely real.

In the Series
In Changes, Molly puts on her light and noise show—"One-Woman Rave spell"—distracting the Ik'k'uox to keep it off Harry who was injured and couldn't move and it bought time for Thomas and Mouse to get back in action. In Chichén Itzá, she does the Rave spell again aiding in the Ball Court battle agains the Red Court.

In Ghost Story, Molly cast the most amazing illusion when fighting Servitors for the Fomor—Six Mollys run in several different directions, some even doing acrobatic-type maneuvers. Harry said "My gast was pretty well flabbered." Molly also made the sound and flashing light illusion of approaching police so that the Fomor-Servitors ran off.
