That's a build i made for fun and it is really cancerous especially against ranged enemies and enemies that like to set up a fight rather than initiate,you just stay in the back line and spam Their back line with your E and Q from relative safe positions.The cancer part is that if you kill them at lvl 25 and you get to the fountain you can spawn kill people with this.Works bad against enemies who like to initiate and are searching for you and jump on you and really really bad against enemies with many units and illusions.Just remember its just a build for alternative fun of the character and not an optimal one.
