Spell creation

"She was a quite extraordinary witch, you know, but she did like to experiment and one of her spells went rather badly wrong one day."

— Luna Lovegood regarding her mother's death, caused by her spell inventing

Spell creation was the highly dangerous and mysterious art of creating new spells.

Nature

Only witches and wizards with great understanding of and skill on magic were known to be able to invent spells. It is unknown what the exact process was to creating spells other than crafting the wand movement and the incantation. What is known is that it was a very difficult, even dangerous process. If something went wrong, the results could prove fatal; an example of this is Pandora Lovegood's experimentation.

Behind the scenes

• It is possible that Antonin Dolohov invented his signature curse as he is the only Death Eater shown using it and demonstrated a certain sadistic pride when he successfully cast it against Hermione during the Battle of the Department of Mysteries.
• Lord Voldemort likely invented some of the protective spells he used in the hiding places of his Horcruxes, such as the Gaunt Shack and the Horcrux Cave. These spells were dark in nature and difficult for even Albus Dumbledore to penetrate.
• It is possible that Hermione Granger invented the Four-Point Spell, as she particularly searched it for Harry Potter (who is the only person who used it) and the incantation is English.
  • It is also likely that she invented the Dumbledore's Army parchment jinx, given the apparent lack of a counter-jinx or cure apart from the boils fading on their own, as well as being specifically stated to identify traitors from the army.
