Knowing what wand movement to RP is pretty difficult, because short of running to the library mid-RP you'd have to memorize it for each spell. Lumos, for example. Did you know it has a circular wand motion, rather than just a flick?
Well, fear not! I got bored one day and made a page where you can easily reference such information.
Here's the link.It has all of the information currently available in the library for first year spells, as they are all that's currently in the new curriculum, but I will update the page for all additions and changes as they come.
Enjoy.
