Okay, for the record I understand that Master Yi is a damage dealing beast, but what most do not realize is he is damage dealing beast even without fat stacks of ad. Realizing this I started experimenting, mind you I am low elo, but I felt yi did not bring enough to a team fight to be a carriable champ, unless you're playing against ****tastic opponents.

this is not a one hit wonder yi, it allows you to engage a tankier opponent more easily, it does not make you un-killable like an ulting mundo of course. The purpose of this build is for a yi to be able to more viably initiate combat as well as clean it up, the attention will be taken off of you some due to the fact you are not dealing as much damage as most are used to seeing a yi deal, secondly it gives you more options for going into a team fight, and staying there till it's through instead of having to constantly retreat to pop of a W. Works well for running down harder targets or targets that would normally have the upper hand against a glass cannon yi.

Situational items pertain to play style preferences and team comp needs, some would enjoy the extra hp and regen offered by mogs, while others would enjoy the luxury of never really running out of mana in a fight, and with this yi, he can stay in a fight that will cost him all his mana without a manamune. So again I say this build will not be for every one, it is a matter of play style comfort zone, what this build looses in raw stomping power it gains in extend longevity to go in and finish the fight.

to get the most out of this yi some practice with him will be needed, because he does not play like you normally would a yi. This is a team player yi, capable of tanking towers, and absorbing some damage for other carry's on the team, while still dishing out more pain than your average bruiser or off tank.

I am a bronzie, this build has worked wonders in low elo, needs to be tested in higher elo games.

p.s I apologize for vagueness, I have never written a guide for, well, anything before. If any one wants to help me refine this guide, please contact me.

p.s.s Keep in mind comfort and play style mean everything with this build and how you build it, along with the current situation of the match.
