Not Updated For Current Season
If there is already a tank on your team, and you want to be the best.(This work even great against towers.) Ps. This is not a solo lane or mid build.
* Try to go in lane with someone who can stun or slow the target for you.
* Use The W spell to heal up and stay in lane longer.
First you buy Dorian's Blade (under life steal)
It gives you durability and some life steal witch will improve you'r W spell (Vicious Strike)
Then when you get enough gold to buy Giants belt or Berserker's Greaves, do what you feel like atm. If you do not get enough gold you can jungle a little.
Right after bee sure you got the Berserker's Greaves so you can buy the rest or all of the Frozen Mallet when you afford. This give you a chance to slow our enemies with axe (Q), exhaust, ghost and Frozen Mallet.
Now you can buy Atma's Impaler That will improve your attack damage, now you'r starting to get dangerous because of your passive that increase you'r attack speed.
But we need a little more attack speed, so you do not have to run around with half HP to bee really dangerous. So then we buy a Phantom Dancer, starting with the Zeal of course. Now its really easy to pick up enemies.
Now you got a quite big amount of HP, but if you have little left just kill a few minions or monsters with the W spell. You got approximately 50%crit chance so you heal fast.
Now its time to buy the Item that makes you as good as God. Infinity's Edge. Start with the Bf sword if you can, then crit.
Now every time you hit with the W spell active, it can crit with 1000 or more. So now you can chose what you want, but i prefer Warmog's Armor So the W spell and Atma's hit harder and you do not get nuked that easely.
Now start raping and plundering as Olaf would say!
