Normality

Normality? That seemed like an odd thing to find in a book like this. His curiosity awoken, Harry opened the given page and started reading.

After finishing the chapter, it was clear that this was much more interesting than the name would suggest. Basically, upon casting the spell "Usitatus Omnia" every of the caster's actions is considered normal and only upon casting "Usitatus finite" this effect is ended. this alone opened up countless opportunities, things he didn't even dare dreaming of could now be within arms (or spells) reach!

But that wasn't all. There were also options that made only specific actions normal, or made whatever he did to a specific person seem normal. The most interesting of all, however, was one that made whatever he said about something the new norm, and if need be, changed reality to make it fit. For example, if he said " Every girl is now in love with Harry Potter," that would instantly become reality.
