Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Building the Awesome Olaf
Olaf using dps items instead of the common hp sort of build people use.
First start off with longsword, this will give you some nice early game damage and it will help you build the tiamat ASAP
Once you have the money for the pickaxe teleport back, this will further increase your damage (or buy the health regen component if you die.)
Once you get tiamat you should be able to effectivly farm minions as well as do aoe damage to champians which when used will give your W ability a little more bang for its buck near minions.
Next comes berserkers greaves, if you have to shop before you have the complete then i would recommend going with attack speed since running is not part of Olaf
Next comes the bloodthirster, depending on how well you are going make a decision wheather you need the life steal straight away, since holding out for it meens you can get BF sword 400 gp sooner thus increasing the damage of Olaf by fifty points.
After you have completed bloodthirster you should be a killing machine, remember because of his passive you should never back down from a fight unless you stand absuloutly no chance either that or they have stun and you do not have your ult up
Next get infinity edge, this will give you critcal hits every 5 or so hits (which is very fun with your W ability activiated) then after you complete that, move to frozen mallet, this will give you 700 HP which will improve the W ability as well as slow targets so they cannot run from Olaf
Now comes the last item another infinity edge, giving your hits an extra 80 Attack damage and 40% chance at critical hitting
Before level 6 unless a team mate helps you try and keep out of combat a bit, although do not b frightened to got for a gaurenteed kill, or you can gaurentee and escape.
After getting ult ultimant, try not to use it until you are at about half health or less, this way they commit to trying to kill you and you can attack faster and to get health back, basic attack till yoy get to around 50% health and then activiate abilitys in this order R E W The r will prevent damage done to you, the E will deal significant damage to them, damage to you as well (reduced by r) and then w, and then keep hitting them, if they try to escape you q to slow/hurt them
Towers, are also pretty easy try having a few minions around to take a few hits for you, but it is not a must do, unless you can gaurentee you will not get ganked, when you start combat with it activiate W and you will see the tower health dropping.
