HI guys, I am a big fan of Olaf and i love to use this OP build. In this guid I am gonna show how u can get the great stats with olaf and hoe to be immortal!!!

The runes are not much to talk about. It is much defense, and that is something he needs cause he is not a carry, but a burster. The armor penetration is helping to burst enemies down.

Dorans shield: It will give a great defensive power in the early game, but olaf is not a early
game champion, so it is smart to just farming creeps in the beginning.
Forzen mallet: Frozen mallet is one of the best items in the game and u gain great health and
great power to chase other and give the team some kills.
Atmas impaler: Atmas is a great item on Olaf, this give olaf much armor and a lot of damage
cause of his high health.
Zekes herald : Zekes herald give you a great 1 vs 1 power and u give the team a lot of attack
speed and lifesteal.
Warmogs Armor: Warmogs is great for duarablity and to get more from the atmas
Thebt. or phantom dancer: Last it is the bloodthurster or phantom dancer. Great items

In the early game it is smart with olaf to just last hitting creeps, he is not strong early game. Just last hitting!!!

Ignite: This spell is for just take the kill or pick up kill steals
Ghost: Ghost is the best escape/chasing spell on olaf, if you combine ragnarock and ghost.

Hope You enjoyed my guide and hope you start playing olaf more because he is a freaking BEAST!!!
If you think it is something which could be better with this guide, just comment that!
