In this build you will find the required items, runes, and masteries needed to play an attack speed Kassidin like a pro. The main reason i like to play an attack speed kass is becuase one, you never run out of mana mid game, two, because inbetween your abilites you hit them pretty fast and hard, and three, its just fun.the items above will give you the nessacary attack speed/Ability power/ attack damage/rape sauce to be able to start a fight, and hopefully end it quickly :D

please tell me what you think of this build i could really use the feedback :D :D

I chose to use attack damage marks ( i know i know....hes ability power) because of the attack speed side of kassidin, if you cant hit worth a **** your damage output if going to be reduced alot. for seals i used ability cooldown because its nice to have the cooldowns of your abilites be a lil shorter so you can spam them faster in a fight. and for glyphs i chose to ues attack speed...its an attack speed build...get some attackspeed. and for quints i aagain....shocker...picked attackspped...

For masteries i went with the offensive tree besause it provides more of an edge for kassisdin. it will give you extra crit(with an attackspeed build this can add up quick) and it buffs your exhaust reducing armor and magic resist ontop of the slow (YAY!), reduced cool downs, and incease attackspeed (again YAY!)

first thing first you need to get your starter item, i like to go with the dagger in the Beserker greaves just to give me the edge in attackspeed in the beginning. after that i stay in lane till around level 6 or i have enough money to buy out my Greaves. then i lane untill i can buy a guinsoo's rageblade, i like this item because it gives you attack damage and ability power and a stacking attackspeed buff (it buffs your abilites and your auto hits). after i build the rageblade i go to a nashors tooth because again it buffs attack speed and ability power while giving you ability cooldown and mana regen. after nashor's tooth i build a malady becasue it gives you more attack speed and ability power on top of lowering enemy magic resist. after i build malady i build a madred's bloodrazor because it buffs your creep farming, armor, and damage output, it also gives you a 4% HP shave off of any target (nice for killing tanks and other studry champs) and again attack speed. and for the end peice i chose a black cleaver. it gives you attack speed and atack damage, and it lowers enemy armor with a stacking debuff, which is ALWAYS handy :D

the order you pick abilites with this build is not really important, i chose to level them all evenly because thats how i like to play my champs, but if you need a faster nuke fill null shpere first then riftwalk. while filling rift blade and firce push in between the others.
