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 Dresden first started to mentor Molly Carpenter.
It is used in making veils and other powerful mind tricks. The only limits of verisimilomancy is the caster's imagination and power. The larger the area effected the more power it takes. These illusions can be both visual and auditory.
The White Council doesn't put much stock in illusion magic because anyone with 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 other measures.
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, veils to become invisible, and even conceal her smell to some degree.
Lash uses several illusions on Dresden that feel completely real.(reference needed)
In the seriesEdit
- Main article: Changes
In Changes, Molly Carpenter puts on her light and noise show—"One Woman Rave spell"—distracting the Ik'k'uox to keep it off Harry Dresden who was injured and couldn't move and it bought time for Thomas Raith and Mouse to get back in action. In Chichén Itzá, she does the Rave spell again aiding in the Ball Court battle against the Red Court.

In Ghost Story, Molly Carpenter cast her most elaborate illusion when fighting Fomor servitors for the Fomor. Six Molly-illusions run in several different directions, some even doing acrobatic-type maneuvers. Harry Dresden said "My gast was pretty well flabbered." She also produced the sound and flashing light illusion of approaching police so that the servitors ran off.
