This is just 2 builds ive seen bits of and decided to combine them and it works well for me. Let me know what you think.

This is build only unless i hear more from people saying its a good build then ill do a full guide.

This is pretty straight forward build but some people may not like the dorans ring first but if you can play her decent enough dorans is still good as a starter imo. But main goal of build 1 is to get that spell vamp ASAP and once you do you can easily sustain if you pay attention to your passive, ive been able to recover around 1/2 my champs hp with one cast of that and the more the minions/champs you hit the better. The rest of the build is just to get more AP and hurt them more in the end.

This second build is almost like trying to make a house with you getting all the foundation items first then building the rest of it after. This build id say is for people that like to be aggressive or like to poke the enemy lane a lot since you can start to spam that Q a lot. A little more dangerous than the first build because you wont have as good sustain/spell vamp to keep you alive if your hurt. The Void staff at the end and the Deathfire Grasp are both optional items to grab last in your build.
