^ I would think that the magic version of AS is CDR, which he has included in the item. Perhaps raise the cost abit Zilla, and make the CDR 10%? 5% is rather insignificant and doesn't really fit well with AP, the only 5% item I can think of is Randuin's, and that's only there for nostalgic reasons..
