Have you ever played against that one master yi that you started screaming I have been playing with master yi for quite some time. I have tried attack speed attack damage ability power but I see this build work the most. I thought I should share this with you guys.

The items I have bought may seem obvious but they work the best! With this entire build you are critical striking 100% of the time.

I like to start of with a dagger which gives you a 15% attack speed boost which i find helpful for the beggining gank.

Afterwards i buy a Zeal which eventually leads into a phantom dancer. Zeal helps with crit and movement speed and attack speed all crucial for master yi.

I buy boots of swiftness because this make Yi very slippery and if they dont have a stun or slow you are out of there :D

Afterwards i buy a phantom dancer which is essentially just a better zeal.

I next buy and infinity edge for damage and crit. Its passive is very good for yi and instead of him criting 60% of the time for 400 he crits 60% of the time for 550 a considerable difference.

Now after the Infinity Edge i buy an Emblem of Valour a very good very cheap item. It gives you 17% lifesteal which is fantastic.

Now to just make everything better buy another phantom dancer making your crit 100% of them time and your attack speed is absolutely ridiculous and even without using your ult (Highlander) your movement speed is 600!!!

And by that time you should have won or withered away their spirits into a surrender. But if not just get a Bloodthirster
