The Wizarding world is full of many magical spells and potions. Some regrow bones, some cure all poisons and there are spells to fix broken objects.
We all know food cannot be created and the dead cannot come back to life. Putting Gamp’s Law aside, are there any spells you would like to create or see added? Maybe creating one will get you a spot on a chocolate frog card.
Personally I would love to see a spell that cures poor vision. 20/20 for all! No need for glasses? I had this thought while thinking of Harry Potter himself. (If Hermione can cure her buck teeth, why shouldn’t Harry fix his vision?) Muggles have laser vision surgery so it does not seem too far off that the magical community would have their own solution.
