( There is notes on the items too btw )
Estimate 4300 dmg in 1s
+ Normal Burst Combo :
E - AA (1stack) - |Q - W(3stacks) - Hextech Blade| (Do this all at once) - AA(trigger passive) ( ignite to secure if u like )

+ Fun Combo to blow ppl mind :
E - AA(1stack) - AA(1stack) - Q - W,Hextech ( BOOM gone ) ( ignite to secure if u like )

+ Always go mid
+ Run right away to the river bush of midlane ( the bush that is closer to the turret ) the enemy will likely have the habit to stand next to the wall that is close to the turret waiting for cs ( This wall create a 60 degree blind angle ), when the cs is half way , get out of the bush and give him an AA + Q ( half HP bar LUL )
+ While farming try to lower the 2 of 3 melee minion hp that can almost be kill , wait for ur cs to lower them to killable with Q and another one to killable with AA when the enemy get closer to get his cs instanly AA 1 of his minions and then Q then AA on him ( This will make Q only split 1 to the low health minion and 2 to the high health minion and 3 to him , if the low hp minion is not killable by ur 1 of ur Q , ur Q will give the minion 2 so less dmg on the enemy champion )
+ For late game u can even win with 4 v 5 , 1 afk player , just tell ur team to patient and keep sniper with ur W until they r ****ed :)))
+ When a champion is almost dead and hid inside the tower along with his teammate , simply W on his teammate and R sideway hextech the low HP guy and Q then run away with E
