I am looking for a book series that I read between 1988 and 2000, but I can't recall the title or the name.
The first book starts with the main character being chosen to learn magic. By the end of the book, he is decent at the rudimentary spells but does not progress any farther as he is banished from the school due to his involvement with killing a teacher. The series goes on with him learning different spells such as shapeshifting, and time travel with each book.
There is a particular book that features him fighting off the influences of a statue that he finds with the cover art of the main character overlooking a stormy ocean with the old woman standing in front of him with her back turned.
There is a particular scene that I can remember where the main character, now much older, is attempting to gain access to a castle but is blocked by magic wards. To remove the wards, he must strike a bell tower with a bolt of lighting at an exact time. He fails to hit the tower but sees a second bolt of lighting appear from seeming nowhere to hit the tower. He later discovers that this second bolt of lighting was from a version of himself that had learned to travel back in time.
