welcome to this yi build i came up with it's totally custom and i would prefer it as i do my self for ma tankiness and damage

the runes you will be using in this guide will be tier 3 armor pen runes for marks and tier 3 armor runes for seals and tier 3 armor runes for glyphs and for the quintenses i use 2 crit dmg runes and 1 armor pen

the way i made this mastery build is because for the max damage and early lifsteal at start and a bit of armor

my item choices are you buy boots and pots then you go convert them into berserker greaves then you build your lantern after that i go straight for the frozen mallet for tankiness and health then your going for your phantom dancer and you buy an infinite edge after that then last but not least you go for your guardian angels

i like to use ghost for max speed when enemies are running away combining it with your ult for max speed to catch those peskey rascals and i use heal for the tankiness so you have a longer life span and slight advantage

this guide is for tankiness and damage for max kills and what not this is my first build thank ya for trying it
