so i rush black cleaver, frost fist, frozen mallet as my third item, take blue buff whenever i can, the frozen fist help with CDR / MANA, and slows enemies as well as doing physical damage to them. i then get the frozen mallet for more HP and damage. i don't buy boots, i use my E,Q,W combo to rank lanes once i get 2 items, get more fed, and q,e in my melee form to gap close and secure kills.

BY this time i should be fed and i get blue buff, i mainly get tanky with a life steal item such as BLOODTHIRSTER, then i would get DEADMANS PLATE to help with the movement speed. last item can get an ap item or you can build ap resistance more from the beginning to help sustain or just life steal. but the last item should be armor pen like MORTAL REMINDER, i cheese in lane with ignite and flash.
