Start aiming your Q at your enemy, When u shot it, use your W under your enemy. Then go so close to your enemy as possible, and use your R(ulti), and follow them to the ulti stops, and stuns the target. And if u are ahead to die, just use your E, that will help your a lot.

To get a lots af minions, u need to be ready to place your W. But wait to place to the minions are placed, so the melee minions is attacking your melee minions, and the ranged minions are also attacking your melee minions. And if you are good, you can place your W, right in the middle of the enemy minions.
