I was going to ask about the magically appearing staff, but see that question was already raised? It might've helped if you had made clear in the story what you explained in your author response. You know what's going on in the story, but your readers don't. So unless it has to wait for a later development, narrate it as you go.
As for the cliches, I think a mountain is being made out of a molehill. While I see some echoed ideas (what story doesn't do that?, you're telling your own storyline.
I do agree, however, that the chapters are a bit short.
I hope to read more!!
