This build gets extremely powerful late game with the really high critical strike chance mixed with movement speed and extra damage. This build used for extremely high dps (damage per second). If you attack from stealth with this build maxed your attack speed will hit 2.5 which is max. With the Phantom dancer x2 plus infinity edge combo you will have 80+ crit chance. Extremely high critical Strike chance Mixed with max attack speed and high damage you can't loose. If you gank and get fed early the only thing that will rival you is the Nexus Turret! =] Good Luck and Have Fun!!!
