Template:A Beginner's Guide to Transfiguration - Avifors

The question of quantity is the one on which we must exercise ourselves next, specifically how much is too much when it comes to Transfiguration? This spell, "Avifors" creates a bird from available materials, but as your skills expand, you will find your flock grows also. The end result can be something like this - Avifors! (the room is suddenly filled with literally dozens of swooping, tweeting birds) Reparifarge! (and a chandelier crashes to the floor between desks).

I trust my point is clear? Consequences, ladies and gentlemen, we have to consider consequences. Not merely can we, but should we needs to be ever at the front of our minds if we seek to claim the title of responsible wand wielders. "Avifors" is a straightforward incantation, but the wand requires a double loop twirl which may call for a little practice. I'd like you, without your wands at first, to just practise the wrist role with me. All together, like this. Well, that was adequate, so we can move on.

Each of you take one book, place it upright on the desk in front of you and cast "Avifors", then, as quickly as you can "Reparifarge!", and we'll see how it works out, shall we?
