The only things you need to know about this build is that as Master Yi, you are probably going to get focused (as you are a VERY squishy champion and your the AD carry) and that you might need a frozen mallet earlier in the game than the build suggests. Also, I dont have a rune selection because I'm not one to waste money on runes. Sure they may be helpful, but I'm gonna save up for buying champs, not runes. Anyway, this is the build I was going and I went 33-4-9. If not for me, we would have lost the game.

I rush attack speed on Yi because of his e's passive. It grants you extra damage. If you are getting focused, leveling up your w might be wise, so you might not get high early damage. If this is the case it might be a good idea to get a B.F. sword before it gets any later in the game.

This build is not suggested for jungling, soloing, or going mid. Just for going AD carry.
