The wizard needed a penny, a crow's feather and a magic wand to give Chris Traeger wings.

Explanation:

To leave the sentence with the correct punctuation it is necessary to add a comma after the word "penny." This must happen because the narrator is listing elements in sequence and these elements must be separated by commas with the exception of the penultimate and the last element, which must be separated by the "and," as was done between "crow's feather" and a "magic wand.
