In the Harry Potter book series Harry finds Snape's (Half-Blood Prince) old Potions journal. Not only does it help him with potions tremendously, (let's face it, Harry is a total science fluke) it also shows him new spells Snape created to probably use on James' band of hoodlums for picking on him, as well as other bullies.

First question: How does one make up their own spell? Any steps at all? (Remember references please.)

Second question: What other list of spells and information besides potions resides in Snape's old diary/ potions notebook? (Again please cite and reference.) Thank you!

    This isn't entirely relevant as everyone knows what you're referring to, but the pedantic side of me won't leave it alone... It's Snape's old potions textbook, not a journal/diary/notebook - granted, it was heavily annotated, but it was a textbook and that's how Harry ended up with it to begin with, otherwise he would never have had it in the first place. Ok - pedant satisfied :)

There is on the Harry Potter wikia information about Spell Creation though not much goes into how it's done...


It lists a various amount of sources and citations even alleging that Lockhart was capable of doing so in the Behinds the Scenes section..

It is possible that Gilderoy Lockhart was a spell inventor, as he seemed to make several spells (Deboning, Peskipiksi Pesternomi, etc.) up on the spot. This would explain why he did not expect them to work the way they did all of them producing the correct effect (etymologically speaking) bar Peskipiksi Pesternomi.

Anyway the website shows the list of wizards whom created spells and which ones including the ones Snape did.

Severus Snape








All spells recorded in his copy of Advanced Potion Making were also crafted by him. Created between 1977 and 1978

Wikia has a list of non-potion spells here (with references).

They are Sectumsempra, Levicorpus, Liberacorpus (counterspell), Langlock and Muffliato; as well as Toenail Growth Hex.

As Kevin noted, the creation of new spells is discussed on SFF.SE before: Can wizards create their own spells?
