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.
Olaf is a beast that can be built in many ways. He has great survivability and will almost always win in a 1v1 match if played correctly. While he can fall behind early game and not come back, Olaf can destroy entire teams if left unchecked. While there are many ways to build Olaf, here's the one I like. Keep in mind that this Olaf is NOT designed to jungle. Feel free to use any parts of this build you want - you may like my items, but not my masteries, and obviously only take the skill masteries if you're taking that skill.
For Summoner Spells, I usually grab Heal and Exhaust on Twisted Treeline or Ghost and Exhaust on Summoner's Rift, because it's so much bigger. You could also choose Teleport, Cleanse, Flash or Ignite as spells, depending on your preference. Obviously, just change your masteries accordingly.
For runes, I would definitely take armor penetration marks, flat magic resist glyphs, and flat health quintessences. For seals, you can either take health per level seals or mana regen per levels seals if you are worried about mana starvation.
For items, I recommend starting with a Doran's Shield for the survivability it grants him early game, and, of course, a Health Potion. Next, build Berserker's Greaves as quickly as you can. After that, grab the pieces for Frozen Mallet in this order: Ruby Crystal, Long Sword, Phage, Giant's Belt, Frozen Mallet. Frozen Mallet is a crucial part of most Olaf builds because it grants him survivability, extra damage on Vicious Strikes, and great chasing power. Last Whisper is next. It is fairly affordable and armor penetration means more damage and more lifesteal on vicious strikes. These are the core items for any Olaf build. At this point in the game you should evaluate your opponents and their builds and build accordingly. In most instances build tankily, with a Giant's Belt for a later Warmog's Armor and then Atma's Impaler to capitalize on your monstrous health, followed by the rest of the Warmog's Armor. After that you can sell Doran's Shield to get either the Bloodthirster, Guardian Angel, or Infinity Edge.
Let's talk about actual gameplay. You're going to want to take a side lane, preferably with someone with a stun, slow, or taunt. Ideals lanemates are Taric, Rammus, Nunu, Shen, Alistair, and so on. Start off last hitting minions and harassing the enemy when you can with reckless swing to get them low, and if you see and opportunity go in for the kill with exhaust. When you pick up Undertow, use it to slow enemies so you can close in for Reckless Swing. If you're getting outranged constantly, pick up Undertow at level 2 and Vicious Strikes at level 4, then proceed with the normal skill order. Use Ragnarok in conjunction with your other abilities to Tower Dive, and use undertow/frozen mallet/Ragnarok to run away. If your team didn't feed, you should be able to take out most DPS champs 1v1 or even 2v1. An important thing to note is that the axe, when thrown, shows the area where it landed for a brief second, so you can use is to scout ahead. Lastly, in team fights focus the carry as much as you can with all of your abilities.
