"The ideal starting point for every student of Transfiguration." — Advert at Flourish and Blotts [src]
A Beginner's Guide to Transfiguration was a textbook on Transfiguration by Emeric Switch. [1] This textbook was used as an introduction to Transfiguration for young witches and wizards, it contained basic transformation spells. A copy of this book cost 1 Galleon at Flourish and Blotts. [3]
It was a required textbook and as such was on the list of items needed by first years for Transfiguration classes in 1991 and 1992 for first [1] and second-year [4] students at Hogwarts School of Witchcraft and Wizardry.
Before Ginny Weasley's first year at Hogwarts, Lucius Malfoy managed to slip Tom Riddle's diary into her second-hand copy of the book in Flourish and Blotts, leading to the re-opening of the Chamber of Secrets in that term. [4] [2]
When Transfiguring, it is important to make firm and decisive wand movements. Do not wiggle or twirl your wand unnecessarily, or the Transfiguration will certainly be unsuccessful. [3]
Form a clear mental picture of the object you are hoping to create before attempting a Transfiguring spell. [3]
Beginners should say the spell clearly. More advanced wizards do not need to say the spell aloud. [3]
Incomplete Transfigurations are difficult to put right, but you must attempt to do so. Leaving the head of a rabbit on a footstool is irresponsible and dangerous. Say ‘Reparifarge!’ and the object or creature should return to its natural state. [3]
Larger creatures are difficult to Transfigure except by skilled and powerful wizards. Know your limits. [3]
