Although it works, you seriously don't want to spend three points in that mastery for an AP champ. Assuming you have 0.75 attack speed and 70 attack damage (high for ap champs at early levels), and that you are constantly autoattacking (which you shouldn't by any means) you would recover 9.45 health a minute. That's crap since you would heal just the damage of a lvl1 hability of the enemy champion used every 6 minutes or so.

If you have some points left and want to focus them on autoattack staff you better spend them on butcher for better last-hitting.
