If you could perform magic and came up with a "new" spell what would it be called and what would its purpose be? (Ex: Lumos to bring forth light from your wand)

Flamio corpus, it causes your body to erupt in flames, extremely painful and hard to put out.
Flamio as in flame and corpus as in body.

PANDOMORUM LOVIS.....IT MAKES YOUR INSIDES SPLIT IN HALF SLOWLY AND PAINFULLY FOR A FEW MINUTES.

Any spell in relationship with practical stuff such as house chores or repair stuff in the house or in my car. OK, "Reparo" and "Scourgify" already exist but just for fun sake, let's see...
- "Pulveris Disaparecio" (to remove dust)
- "Finestra Lavare" (to clean windows)
- "Petra Oleum Reservatoris Repleneo" (to fill up my car gas tank)
- "Aerium Pneumaticus Repleneo" (to fill up my car tires with air)

Oh well. Just having fun.

A spell that keeps me inspired/motivated when I'm trying to do something. Although I have no idea what it would be called.

Cognitus Infinito. Expands the capacity of the brain to allow the absorbtion and perfect recall of boundless amounts of information.

One that can create and find fun things to do.

Or one that can bring drawings to life and characters out of their books.
