this is a build that trolls the other team hard for this to work you need a jungler with smite because you are going to do that too. There are 2 reasons for that first and formost its so that you can take dubble golems at the begining to get level 2 then you want to do that as often as you can keeping in mind that your jungler might need to kill them too so when you arnt going to take dubble golems you should use smite to kill minions in your lane its alot of gold so use smite when its off cd.

i know armor pen is more populere but i like ad marks insted of armor pen on this build. You can use armor pen marks if you want to doesnt matter much also you can use hp seals insted of armor if you want to just like armor more ^^

not much to say some good offensiv masteries for dmg and so on and ofc emprooved smite and ignite masteries when you are going to use those summoners anyway. Some people might say that the ignite masteries is usles on ww but the extra ap when its on cd helps you heal more with hungering strike wich you are going to use to stay in lane.

first off id like to say that if posible you shall go back when you can buy berserkers greavs and emblem of valour and then you shall buy the items in the order it says up there,
if the next item you need lets says its phantom dancer and you are going back then you should buy as many items needed to get that item and if you need to choose take the item you find the best to take.

Pros:
life steal
never needs to leav lane if you play him right
great farm
easy kill at lvl 6 or befor

cons:
aginst 2 with stuns his ult will be wasted

this build works realy good in ranked and in normals
