It is mine fist guide ever so... At First i want to notice that i'm from Poland so i can do a few mistakes in writing. I play Yorick a little bit and i think that build that i make its the best (for me of course...) A lot of people says that Yorick is UP but this is not like that, he is just balanced REALLY!!! This is a guide to show you how I play him and and dear reader, do not expect that you'll be crush everithing everything that moves becouse as I say he is BALANCED!!!

On him i take 9 Marks Magic Penetration becouse two of his skill hit by magic not DMG and Seals and Glyphs to be a little more tanky and Quitessence to have a little bit easier start.

I take 9/21/0 to have Magic Penetration on attack tree and 21 to Defense to have of course a defense

I get as fast as it possible life steal becouse with yours Omen Of Famine you got two lifesteals so... Next item should be Giant's Belt to have more Hp this is our prior because Yorick is a little bit squishy at the beggining and it will help us to get more DMG cuz after you will have Atma's. Boots... i always get Mercury's but if your oppoenent is DPS team you can get Bereseker's cuz you will have Armor form Atma's and Sunfire Cape. Bloodthirster is must have on him cuz this item give you a lot of DMG and lifesteal. The last one... if one of yours opponent buy and Madrezor's you should/must buy Sunfire cape but if you see that no one will buy it you can surely pick Warmong's
Of course you must always adapt to your opponent

Max out your Omen of Famine to be on lane as long as you can. Next should be Omen of Pestilence cuz it will help you to run away( it's only skill that give that chance) or chase your opponent( same us up). The last should be Omen of War cuz his DMG will help you at the late-mid/late game in TF's or 1vs1. Of course always try to max your one of the AWSOMNESS ULTIMATES!!!
