Pros / Cons

Early game your Alpha Strike does nearly half the enemy mid lane's hp!
Your Meditate is great sustain!
Highlander refreshes Alpha Strike every time you kill someone making pentakills easy!
Late game your Alpha Strike and Lich Bane can kill a squishy!
Enemy's always underestimate the power of AP Yi!
Hes extrememely fun :D
CC completely owns him.
Really squishy.
Hard to do well if not fed early game.
Long cooldowns.

Summoner's Wrath and Summoner's Insight are for Ignite and Flash. I get all the AP I can get in the Offense tree. In the Utility tree, I get Meditation for mana regen and Runic Affinity for longer buff durations. If you are under level 30 then start with the Offense tree then going into the Utility tree.

Skill Sequence

You want to get Alpha Strike up to rank 5 ASAP because it is your main damage ability. The order of skills is Highlander > Alpha Strike > Meditate > Wuju Style getting a point on Wuju Style at level 4 for a bit more AD.

Summoner Spells

- useful to finish off kills
- for escaping and initiating
- to get out of cc if they have a cc heavy team
- synergises well with highlander
- if your facing ad in mid
- you dont need it, leave it for your top laner

Core Items

Mobility, Magic Penetration, its awesome :)
Adds to your already insane burst
Best AP item in the game

Guide Top


You have 3 starting choices:
Personally I like to start off with Amplifying Tome and Health Potion becuase you can get a kage's lucky pick pretty early on in the game for that extra gold and it is the item with the highest ap that you can start off with.
However, if you are vsing an Ahri or Swain etc. you should start off with Boots of Speed and 3 Health Potion.
Mid game you should have completed your core items. This is when you will dominate, Deathfire Grasp their AP/AD carry and Alpha Strike will kill them instantly giving your team the advantage.
Late game when you have finished your build, you are very squishy so hide behind your team until one target is low enough for an alpha strike to kill. This is when you will pounce. Alpha Strike the team with Highlander activated killing your target and halving everyone elses health, Deathfire Grasp the one that was not hit by your Alpha Strike. Alpha Strike again and Lich Bane the tank giving you and insta-penta! Make sure to time this correctly and let them use their cc first as any stun will kill you.

Situational Items

Good AP, AS and CDR.
Against CC or AP.
Against Tryndamere Olaf or any other hard hitting bastard.
Against a heavy AD team.

Guide Top

Enemy Laner

Ahri 3/10 - Not that hard, just get Boots of Speed and dodge her abilities and your good to go.

Annie 8/10 - HARD ONE you want to play really defensive against her because of her ANNOYING stuns and insane burst giving you no time to meditate.

Katarina 2/10 - EASY your Alpha Strike out damages her abilities and you have a built in heal, just keep harrassing her down.

Akali 6/10 - pretty scary once she gets to 6 as her burst is amazing and if she stealths while you cast your alpha strike it wont hit her, in this lane you want to just farm up and gank other lanes as much as you can.

I will add more when I get more experience. :)
