|"Are you a wizard or not?"
The title of this article is conjectural. Although it is based on canonical information, the actual name is conjecture and may be supplanted at any time by additional information released from canonical sources. If this occurs, please move this page to the appropriate title.
During the international duelling contest in 1379, the first semi-finalist used this spell on himself in his duel against the second semi-finalist. Once transformed into a bull, he proceeded to charge his opponent, who only managed to escape death by turning into a viper and biting the first wizard-turned-into-bull.
If a wizard turns himself into an animal, he is endowed with the animal's brain, and starts thinking like the animal, the only exception being Animagi. Thus, casting this spell on oneself causes the loss of one's mental capabilities, and requires another wizard to cast an appropriate Untransfiguration afterwards.
Behind the scenes
- As bull is the name for male cattle, it is quite possible that the spell turns female individuals into cows.
