Not Updated For Current Season
The whole idea behind this build is based on attacking so fast your lifesteal will keep you alive. It is very effective if u solo.
Start off with vampiric sceptor and lane till you have enough to get either the malady and boots of speed. You can engage squishes with a jump then hit your Q ability and maybe an ignite.
At level 6 when you get your ulti you become very good. Jump past your laning opponent then ulti him back to where you were, hit your q + e combo and you will have gotten a kill.
I will update soon
