Temporarily changes a transformed werewolf back into their human form (according to Gilderoy Lockhart)
- "Simple, yet effective — and another village will remember me forever as the hero who delivered them from the monthly terror of werewolf attacks."
- —Lockhart bragging about his supposed use of this spell to end a village's terror[src]
Since Lockhart is known for providing phony spells, and given that there is no known cure for Lycanthropy, it is possible that this spell does not truly exist or that it has a different effect than Lockhart described (possibly just temporarily forcing a transformed person back into human shape, rather than preventing the change).
Homorphus is a combination of the Latin Homo meaning 'man' and the Greek morphe- meaning 'shape' or 'form'.
Behind the scenes
- Although this spell is described as a charm, its effects seem closer to Transfiguration.
- Considering the fact that there is no cure for lycantrophy, it is likely that this spell were a highly advanced piece of magic which returned the werewolf to its human state, only for him/her to turn into a werewolf by next full moon.
