Works really great, good job.

+1

Pretty good gameplay suggestions. I really enjoy playing AP Yi from time to time. His alpha strike is a great initiator for team fights!

thx guys (:

Excellent build

lol i remember that quadra, and one tiny fail arfur, you took improved exhaust in your mastery tree but you have ignite as your summoner spell -_-
I might use this guide its pretty good =P

Haven't tried it yet, so I won't vote yet, but I've heard (and it makes sense to me) that Nashor's Tooth is great on AP Yi. Gives him AP, AS (helps his naturally high attack damage), and a huge chunk of CDR for faster Alpha Strikes. Why don't you include it, or any mention of it?

^noted.

LOL arfur i was gonna troll but meh
yes i finally read this and commented

kay add a banshee veil or something for optional items o,o you just get owned in the face by cc while you mediate.

Jejeje long time i have been using yi, but first time that i built him like this... its a great build btw, but it doesnt make u invicible, like someone may think.... it make you more powerful than that :D jajaja 10 min of the game and i have earned fb, and two double kills

Fun whenever I want to take a break from jungling yi. :P . Killing a teemo at 3/4 hp with one alpha is fun. Tanking an olaf with meditate while ignite + exhausted and he ulted is also fun. :o

so much for a useless ap yi

Maybe make a mention of the fact that Yi takes the non buff monsters in 1 alpha strike with this build (wolf/wraith) and the two golems too. (alpha strike + smite kills both)

imo Archangels is a great item for Yi (so so so mana hungry) and I would include it instead of Deathfire's Grasp or Lich Bane. Lich Bane is great, but the only reason I see Deathfire there is for the capped CDR, which while nice for spamming alpha strike, is pretty useless when you have no mana. Archangels helps his mana problems a lot and lets him do even more damage with Alpha strike.
