*Early game you just focus on getting those creep kills and try to have some one to stack jungle for you
You'll have 6+ hp regen which is kinda okay early game to keep you on a constant gains

*Mid game you should have at least armlet and echo to be useful in team fights.

*Late game you start replacing armlet and echo with the listed items. (get hyper stone when ur done with buying all required items "NOT BEFORE")

*Laning : With your cleave you can harras / dmg enemies in lane with just hitting the creeps between the both of you, that will keep em at bay.

*Start ganging other lanes as soon as you get dagger

*Hitting stuff : MAKE SURE TO USE YOUR PASSIVE CLEAVE TO YOUR ADVANTAGE AS MUCH AS YOU CAN!!!
