Nice build, I do suggest against leveling W first, E deals alot more damage and makes farming a breeze. Also never use W for farming, it's your only escape ability without it you get ganked so easily! Only use W for farming when your under your tower last hiting and your at max health.

Ahh didnt notice that. Thanks ^_^

If you're going to buy a Void Staff, PLEASE buy CDR boots :D

Then you can use 2 blue CDR runes, and then 7x AP :O

Basically, CDR boots > Sorc Shoes when you're going to get a void staff.

Technically, unless you have 32+% CDR with items, and you need 20 magic pen to do true damage, then CDR Boots > Sorc Shoes.

I would keep the Mpen Reds so you can heal better off of minions, but if you're gonna buy a void staff, then you probably shouldn't use Sorc Shoes.

Nice build! ;D
