Follow this build unless you are getting fed like nothing before then jump on the IE just saves time late game.

You will vamp faster then people can damage you so long as your not stunned or slowed. But until that Q in E and R it up and just smash the team to bits until they surrender or you win.

If you wish for more attack speed and crits you should sell your boots at end game for another Phantoms it's just so trolly.

At level One you want to get your Q for the farm on minion kills. After that onwards you want to get E lvl 5 ASAP so just keep leveling Q and E together until you get E level 5, not level 6 though you do still want you ulti. When E is level 5 you want to get Q level 5 then build heal.

The reason for this si because once you have got your Blood Thurster you wont need any other heals because you will farm it up so fast.

Follow these masteries if you wish or dont follow your own trusted build up to you.

I use these just because im a nub at LoL and need to get 5k characters until ma pro build will publish..
