if shaco is near a wall he can q through and surprise the enemy i have done this a lot. you can also use this to escape just like flash but a lot faster cool down. your two-shiv poison will help you get away when you don't have your q it will slow and hurt them a lot. you q at your enemies when running because they will think you are running away from them well you are just not the way they thought
