You can see red (or white) smoke even in the war fog, his Q has 400 ud os blink (flash has 425) and a coldown of 16 seconds and 1,5 seconds invi at lv one.
Is, literally, the dash / blink ability in lol with the highest coldown in the game, and only gives you invisibility.
Most of the times you have to use your early skill points in this skill to down his cd and improve his invi duration, at an ability that don't do damage or improve his damage in any single way, in an assasin!!
Shaco's Q right now sucks, and you have to put, at least 3 points in early to have a decent (decent is not good) blink ability. This meains that until lv7 you have your boxes (main shaco's cc) and your knive (main shaco early damage) at 1. This means that your cc is about 0.5 fear (and 2 seconds to activate) and a huge damage over 50 plus 0.75 ap and 0.6 aditional ad.
So you can raise the enemy but then what, or your laner do cc or damage or you are fucked, because you don't do damage with your abilities, only have your autos (passive is about 130% of your ad, that is 30% more than a auto, and it has cd).
Really stop thinks shaco is still good, is not.
He has a decent winrate because of drakthar (i don't know if it correct spelled :P) and lethality build, that's all.
