The Growth Charm is a charm which causes the target to become larger. During his O.W.L. exam for Charms in 1996, Harry Potter confused this spell's incantation for that of the Colour Change Charm, causing his test rat to swell to the size of a badger when he was supposed to turn it orange.
Appearances
- Harry Potter and the Order of the Phoenix
- It is also possible that Barty Crouch Jr. performed this charm acting as Allastor "Mad-Eye" Moody in the film adaption of Harry Potter and the Goblet of Fire, to enlarge a spider to demonstrate the effects of the imperius curse to a defence against the dark arts class. The incantation he said was "Engorgio".
