On an uncharted continent beyond Valoran's grasping clutches, the conqueror named Olaf was born to a long tradition of soldiers unlike most others. Berserkers, as they tout themselves, are warriors who channel fury deep from their cores, unleashing pure and savage wrath upon their enemies. This fearsome evolution is a product of their unforgiving home, Lokfar - a barren tundra where all creatures must vie bitterly for every resource. Olaf belonged to a seafaring clan known for ruthlessly pillaging any and all villages within reach of their dragon-crested longboats. The last time he saw his icy home, Olaf was embarking on an expedition to pioneer and plunder a distant land known only to legend. However, while underway, a terrible storm sprung up and Olaf and his crew were thrown to the mercy of a roiling and pitiless sea.

His ship destroyed, his crew nowhere to be found, Olaf miraculously washed up untold miles from ''friendly'' waters on the foreign shores of Valoran, south of Demacia. This unfamiliar place stunned and frightened the Berserker, for Lokfar is not privy to such potent magicians. Approaching them, Olaf hoped that they could use their mysterious powers to send him back to his people. A bargain was struck. Olaf would use his awesome prowess as a warrior to serve the unusual wars of Valoran in the League of Legends, and in exchange the sorcerers would find him a way to return. Despite his participation in the League, Olaf knows better than to trust the ''finger wagglers'' that run the Institute of War. He deliberately keeps details of his life and home from them. After all, with enough information, they would most certainly find the Lokfarians and dominate them as they have dominated all of Valoran, keeping both quietly -- and unwittingly -- in their thrall.

This is my Brolaf build. It leaves you with great damage, attack speed, lifesteal, hp, armor magic resist, and move speed. Another reason I wanted to add this build is because of the cost of the items. A lot of Olaf builds are impossible to finish building because of the price of the items are ridiculous. You can't expect to get a black cleaver, bloodthirster, and infinity edge in a game... With this build, you will be carrying every game you play.

I picked 3x armor penetrationon runes because Olaf can be pretty ridiculous in armor penetration towards the end of the game with the comination of his ultimate's passive, ragonorok. the end of the game, especially as this build doesn't have additional move speed items besides boots. The armor pen marks are pretty obvious. For the seals and glyphs, I feel he lacks armor and magic resist so I get MR and armor runes per level. They have worked really well for me.

For masteries I take the armor pen in offense and a few points in increased base dmg. and move speed in utility. Again this helps with Olaf's speed issue and I only get 2/3 for brutality mastery because the 3/3 points in the move speed utility is far more vital to olaf's speed issues.

I find that starting with a cloth and 2x blue 2x red potions work really well. You are already at a good base move speed at 330, and you got some good armor and magic resist to start. Once you get wriggles and beserker greaves, I occasionally leave my lane to get some jungle buffs, they really have a big impact on Olaf's kite ability. Then you pretty much build the rest of the items until you finish the 5th item, the Atma's impaler. At this point you have the option of building, banshee's veil, randuins omen, or warmogs. I take the banshee's when there is a ton of cc or ap damage. I take randuins if there are alot of dps enemies. And i get warmog if it is a mix of both. It helps add dmg to your "w" and atmas impaler. After buying one of the 3, i sell my wriggles lantern for a bloodthirster, if the game lasts that long. This can put a huge edge on olaf!

I find that olaf's throwing axe is his most important ability. It allows him to chase opponents if you can line it up correctly and pick up your ax while chasing. With all of your armor pen, it does incredible damage. I don't get "w" until the end because you get lifesteal from wriggles, and you don't have a lot of health until later in the game for it to affect your "w" enough.

This is by far Olaf's greatest asset. This is the highest priority in leveling up skills. Always use this ability no matter what. Always have it on cooldown. Always throw it into minions and always harass against champions. With all of your armor penetration, leveling up this first give incredible damage output like no other. Also, make sure you cast W before you throw your axe when you can. It gives way more burst damage. With this super strong axe, you can be sure your enemies will never escape. Throw it at them when they run with little remaining life, and you can also be sure it will kill them in one hit!

Ghost is what you want on olaf, with his slow from the frozen mallet, and his throwing ax, enemies will not escape your wrath. Exhaust is the utmost important spell for him. When he runs into a team fight, pop your ult and exhaust their heaviest dps and you will get pentakills!

Overall, this has been my most successful Brolaf build to date and I hope you guys can get some good games with it too.
