You Might Want to think of adding 2 more items for a Full 6 items (after selling starting Dorans item of course) also 1 point into each skill by lvl 3 helps you control your lane.
Enemy chasing you / ally? Fear and drain/run. darkwind 1st is a must for farming.
i Usually go "E" "W" "Q" for skill order then concentrate on drain and Dark wind.

a couple items u might think of adding are an Archangel's Staff ( or 2) and/or Zonya's hourglass/ another Rabadon's Death Cap.

Oh yeah I can't memorize the order of them. But you know just take dark wind and drain...and then one point on fear at level 7-10.

uh... you do know that you have a rank 8 drain and a rank 6 dark wind.
