Glamour

Glamour is a spell that allows the user to change their appearance.

Description
As described in the Book of Fables from The Wolf Among Us:

"Glamours are spells that allow the user to change their appearance. They are expensive, but can be purchased by non-human Fables in order to pass for human among the mundies. Cheap glamours can be found in the seedier parts of Fabletown, but they are often unreliable and prone to sudden failure."

Trivia

 * If Fables who do not appear human refuse to use glamours, they are arrested and taken to The Farm.
 * Beast and Bigby are the examples of Fables who can change apperance without using this spell.
