A Witcher at Hogwarts

A man is reborn in the Harry Potter verse with everything he needs to become a Witcher This is my first attempt at writing so i am open to thoughts and criticism, i don't know how often i will update due to my working 40 to 60 hours a week but i plan to at least finish this fan fiction because it has been an idea of mine for a while to write one instead of reading all the awesome fan fictions I have come into contact with.
