Hey someone found my Guide :D I think you searched for one cause you need some help with playing Master Yi. If yes, then you are right. Im Master Yi Level 7 since 2 Years and i wanted to share some things that i know with you ^^ In this Guide you will learn:
> The right Masteries
> Using Good Items
> Using the Right Runes

Master Yi

I choose the Greater Mark of Attack Damage as Marks for some Early Game Damage, and for the rest of the game more Damage. In the Seals i took some Greater Seal of Armor against AD Junglers. In the Glyphs i took the Greater Glyph of Magic Resist against some AP Junglers. as Quintessences i took the Greater Quintessence of Scaling Attack Damage cause Master Yi got the stronger late game and that what gives him more Strength in Lategame

In the first one on the Ferocity Tree, i took Fury for some more Attack Speed. As Second i took Expose Weakness cause your Team deals more Damage to everyone on the enemy Team, and thats very good in Team Fights or at Ganks. The third one is Vampirism . I take Vampirism cause i like to have Lifesteal on Master Yi, but if you want a stronger Late Game but less Life Steal, feel free to take Natural Talent . The Fourth one is Bounty Hunter . If you take Bounty Hunter, try to kill everyone on the Enemy Team. You get Stronger for each one you kill on the enemy Team. As Fifth one i took Battering Blows . You get some free Armor Pen from beginning on. As Coremasterie i take Fervor of Battle . I like some more Damage and i already took Vampirism so i dont need Warlord's Bloodlust . If you take Natural Talent instead of Vampirism then you better take Warlord's Bloodlust . In the Cunning Tree i took Wanderer . You are faster on any lane, and you dont really need the bonus damage on minions and Monsters, cause you already do lots of Damage. As Second i take Runic Affinity so that Blue and Redbuff last longer.
As Third one i took Merciless cause you want to shred your Enemies away, and with that you can easily finish up lowlife Enemies. At last i took Greenfather's Gift for more Damage with the first hit when you go gank somewhere. So that´s all to the Masteries. Lets go to the Items.

You need to take the Hunter's Machete for the Bonus Exp at Blue Buff (Yea always try to start at Blue Buff). Some Health Potion will help you to survive at least to the Raptors. The Stealth Ward is selxexplaining i think. At your first Backs you better buy a Stalker's Blade and a Recurve Bow for a better Jungle Clear. Control Ward is always helping. Place it at your Blue Buff to take care of it. Buy some Health Potion too, it´ll help you with surviving. Go as fast as you can on the Stalker's Blade - Bloodrazor. After that you build a Bilgewater Cutlass and an Recurve Bow for your Blade of the Ruined King. Build the Blade of the Ruined King as fast as you can. You can choose between the Berserker's Greaves, the Boots of Swiftness and the Ionian Boots of Lucidity. You can choose one of the Attack Speed Items. Choose Guinsoo's Rageblade, Phantom Dancer and Statikk Shiv. At last you buy Bloodthirster and Infinity Edge for Lifesteal, Crit and Damage. If you need some Armor you can build a Dead Man's Plate or an Guardian Angel. Same goes with Magic Resist. If you need some build Maw of Malmortius and Mercurial Scimitar. It will give you Damage, MR, and you can free yourself from Stuns with the Scimitar. So that was everything from the Items, now we go to the Skill Sequence.

Hey, welcome to the Skill Sequence. Here im gonna explain to you why you max. which Skill. You max. the Q Alpha Strike first cause you dont deal much Damage with it on Level 1 so you level it up and it is getting stronger with the Level and the Items. You max. the E Wuju Style at Second cause the True Damage you deal when its activated is getting more. And True Damage is awesome against Tanks. And Tanks counter Master Yi. You dont have to level it Early cause Tanks are scaling hard into the Lategame. I max. the W Meditate last cause i dont think it is really helpful at the beginning. You need much damage on the Beginning and later you need your W. Why you Level the R at 6 11 and 16, is explaining itself i think. So i think that was everything here, so lets go on to the Spells.

Hey, there we are at the End of the Guide. Here i explain why you use which Spell. At first Smite. You need Smite, so that you can buy the Jungler Items, and the Bonus Exp. It helps you at clearing the Jungle and without you cant jungle. I use Flash cause i like to escape with one little click on a button. Some People use Ghost too together with the Ultimate. You can chase people better like that, but i dont really like it cause you cant really escape. You can choose if you want to take Flash or Ghost but you have to 100% take Smite. Thanks for Reading this until the End. I hope i could help you with this, and if you ever need help again, feel free to return to this Guide and read through it again. Thanks for Reading and have a wonderful Day and have fun in Ranked Mode ^^
