This is your bread and butter
What is up? This is my Yasou. Yasou's "Q" Is like GP's Parlley, have that in mind. This is what I've come up with after many different runes/Masterys/Builds. I find it moste useful because Yasou is unpredicteble early game, and you can't take to many crazy moves until you get SHIV. Anyway, try it. Like it, hate it, love it.
Is you can see, i wont go in to deep, cause i have not a single **** how to make a guide nice and neat.
I allways rush SHIV, it gives you all you need 40% attackspeed, plus 20% from you're Berserkers 55% is all you need to get "Q" at its lowest cooldown. I usely go for HYDRA after shiv, works well with everything you do, plus that splash dmg/lifesteal is allways nice. If you get some early kills I buy Infinity Edge befor HYDRA just for the assassinations. And, ICEBORN GAUNTLET Is really good, 70 Armor, and 125% bonus dmg for every "Q" and the slow effect. Now they cant run, or run you over. If you wanna escape, just give them the old "Q" and they will sloooooow down and you will laugh.
