Editing Creating Magical Effects (section)

==Fast Casting==

Its possible to cast a rote that you don't know. Since its not something you've practiced, you're limited to coming up with the Effect on the fly, by improvising based on your knowledge of the Sphere in question. This trick is called fast-casting.

You pick a rote for which you have the necessary Spheres, but that your character hasn't learned. Add one Trait to the casting difficulty. Other than that, you cast the Effect normally.
