Unlimited rapid fire fireworks.

you know that item you get at the moon festival "elunes wand" or something like that, shoots fireworks. when you move behind a wall, and shoot at something out of LoS, it doesnt trigger cooldown, or take a charge, really freaks some people out when you make them super bright with a stream of fireworks.

Yeah, I saw a movie on that. The dude was shotting it at a goblin so many times behind the gadgetzan wall.
