This is m first build to Master Yi. Hope you like it.

My masteries rely on attack damage, critical rate, and magic resistance because Master Yi is fragile and can easily killed especially by magic type champions.

Skills of Master Yi must have is its first skill, the Alpha Strike followed by Wuju style. You can get its second skill later though you bring red pots and blue pots in early game. In level 4 you can get the 2nd skill then.

Runes of Master Yi relies on armor penetration, magic resistance, attack damage, and critical damage.

Items of Master Yi must carry first are boots, red pots, and blue pots. then build it to Mercury boots for magic resist boots. I choose this than Berserker's greeves because later you will build Stark's Fervor which will give you Lifesteal, attack speed and life regeneration. then followed by Avarice blade for additional critical damage and additional gold every 10 seconds. build Brutalizer to reduce your abiity skills cooldown and additional 15 armor penetration. combining these two will result to Youmuu's Ghostblade which will enhance Master Yi's abilities. then you have two options which will be your next build. Choose between Frozen Mallet or The Black Cleaver then your final build is Infinity Edge.
