this guide is good for a late game but in early game it is hard cause it has low defence. so try to get ultimate before you go to engage.

Pros of this build is that you have much sustain and you can stand with your ult and get some kills. Cons are that if you don't engage and run away from someone you will die easily. While u engage your hextech+spirit visage makes you spell vamp much higher and your opponent will flee or die
