There are quite a few , middleage ones , but done with a slightess error can backfire tremendously.
Also can be done only by wizards or their apprentices ( we would say addepts now ).
You can find "Anifornum" in a book called " Wizardology "!
Druids are the most notorious for their shapeshifting abilities. While everyone can do this, those with a close bond to nature will excel much farther. The first step is to identify what your companion animal is. Once you have realized that, you can begin to observe the animal in its natural habitat, etc. After close examination and study, you should be able to take on many of the animals aspects. The great druids were rumored to be able to perform full transformations for great periods of time! But all of this takes practice :)
Shapeshifting and Transfiguration is NOT a literal process.
It is a psychic process.
One can see through the eyes of an animal OR perform night flying in the body of an animal (basically, you tag along). Your body won't physically change.
It is a difficult process, and one I haven't attempted in my 2 decades of practice. I night-fly and cross the hedge on a regular basis, but shape shifting and transfiguration is REALLY difficult, and takes a long time to master without it being dangerous to you or the animal.
I'm with most of the people who replied here. Stop watching harry potter and charmed and the craft and thinking that it's real. It's hollywood glamour at it's finest guys and gals. If you don't realise that, then you have no buisness preforming magic at all. Sorry to be harsh, but that's how i feel.
