Private to Mr. Constantine
It would an almost instantaneous method, I have the spell words needed to make it happen. As soon as this body is destroyed my soul will appear, and my new body will be ready. My soul will be visible, even to those who are not magically inclined.
No, my soul is the same as any other humans'. The only side effect of this process is that you will probably experience "highlights" of my life. I will experience them as you would... Again.
