I don't know how this ended up on the front page. I'll try to say something original.
I think this wizard needs more fleshing out. Perhaps he is actually a good wizard who stormed the house of two evil henchmen, demanded that they tell him where their gang will be performing an evil ritual, and after a brief exchange of violence, gunfire and magic, the wizard killed the two evil henchmen. The wizard didn't expect to find that they had a child. When he found the child hiding in a closet, he saw that the child was shot in the stomach and probably would last much longer. The kid was going into shock, and the wizard had mercy on the evil henchmen's offspring. Whispering "I'm sorry I don't know any healing magic. I do know one trick though, and I can't think of any other way to save you." The wizard waved his Ravenrune staff and cast a spell that imbued the child with blessing of Corvus, the raven god. The child began healing and slowing transforming into the image of Corvus. The wizard placed the child on his bed and promised to return to teach him how to use his powers for good. The child woke later only to find his body a mutated and frightening sight, his parents dead, and only vague memories of a wizard who entered their home, killed his parents, and cursed him with the half body of a raven. The child cried and swore vengeance on the "evil" wizard.

I wouldn't say deleting...
It is not exactly a bad concept. A mysterious sorceror with the legs of a raven, who summons flocks of the dark birds to attack his enemies.
The problem, Agony, is the execution. The Raven Staff (needs a better name and a history) needs it's own item post and background. You should probably be more descriptive with appearance.
THE BIGGEST PROBLEM: THE BACKGROUND!
What is that?! IT'S THE DAMN ORPHAN BACKGROUND!
Point 1: What kind of person just breaks into a house, kills people, and transforms a baby into a half-raven?! That makes no sense!
Point 2: He never noticed he was a half-raven?!
Point 3: Why did he kill them all? There's no motivation!
Point 4: Who left the note and the Raven Staff?
Point 5: TRAVELING THE WORLD FOR REVENGE IS A TERRIBLE MOTIVATION! IT'S THE STUPIDEST MOTIVATION IN THE WORLD! IN... THE... WORLD! IN THE WORLD!
In completion, you've got to improve the background.
(Note: I think I might use this character idea, though, if you don't mind)
Since it could be improved (interesting concept, poorly executed)...
