Master Yi Build
Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
First off, this is work in progress. Secondly, despite the rune suggestions this build was based with bad runes in mind on a level 23 summoner account.
Why the lack of aspd gear? Well, unless the only thing you want to kill is turrets, you need at least some attack damage and by no means is this build without attack speed, it just focuses on items that bring much more to the table. "Oh but attack speed is amazing, the faster you hit, the faster they die" Not true. If you're attacking a brick wall, maybe, but players move and have disables. It's true Master Yi's ultimate is great for chasing, but the less time you're chasing the better
Marks. Armor Penetration, no doubt. Were focusing on max damage, this is the only choice for marks.
Glyphs. You have a couple of choices here. You can go for cooldown rating or you can go for magic resist. The choice is yours.
Seals. Again you have a couple of options here. You can go for mana regen to help with early regen, in most cases you'll have blue golem buff and never run out of MP, but if you play other mana based champions like I do, mana regen seals are the way to go. If not, go for dodge.
Put your first point in alpha strike, it's good for initiating the jungle creeps. Second point, stick it in meditate, believe it or not this is extremely useful while jungling early on and with blue golem buff you can pretty much use it after every cooldown. Third point, put it in Wuju Style for a little bonus damage. Every little helps. 4th put it in meditate for more healing. You shouldn't need to put any more points in meditate after this.
Start off with Cloth armor and 3x Potions.
Next buy your Madred's Razors which you'll need for jungling.
Next item you'll buy is boots. Now boots depend on the enemy teams compositions. Nine times out of ten you want Mercury Treads. If the enemy team has very little magic/disablers I suppose you could go for Beserker's or Swiftness, but I strongly recommend using Mercury Treads.
Now your next item is more prefrence than anything else. You can finish building your Bloodrazor or you can go for the last whisper. Now the reason I get the last whisper is for the armor penetration, but I often feel like there could be better alternatives for this slot. Something I'll need to test in the future. After further testing The Black Cleaver may be a better choice.
Finish up your Bloodrazor and then aim for The Black Cleaver. I have recently tested this and it is much better than Last Whisper for Yi.
Your final item (most likely) will be the frozen mallet. It's another item I don't completely like, but, it has 2 things you need. HP. Yes HP. Yi is actually quite squishy for a melee and the extra HP adds a lot to your survival. It also has attack damage, which again is what were aiming for. Additionally it has a slow effect which is useful for enemies trying to escape. Sounds good? Well, for the most part it is, unfortunately it's also very expensive.
If the game is still going on, which at this point I seriously doubt. Grab more attack damage like a B.F Sword.
Why is there no infinity edge? It's a horribly, horribly expensive item. I don't consider the benefits of it worth the investment. Additionally infinity edge alone wouldn't provide you enough crit chance to be useful. It's just a build I don't like on Yi. Ashe? Trist? Sure.
Early on jungling as Yi is going to be tough, if you're a low level summoner it may even be impossible. Unfortunately I don't have a low level account to try it.
(Apologies for the artifacts on the screenshots, I have no idea what's wrong with them)
Start here. Use your Q on the golems, smite one of them. Kill the other one, if your health is dropping too fast pop a potion, but in most cases you -should- be able to kill it without using a potion. If in doubt, use a potion.
Next you're moving to the wolves. I don't agree with going straight for the ghosts, not yet. Pop your potions, make sure you have at least the amount of health I do in the screenshot. Chances are while killing the wolves you'll need to pop your last potion.
Good, you should be level 2 now. Get meditate. Use it. Look at the screenshot below, make sure you have at least that amount of HP. Use your Q on them, smite the big one. Kill the rest. You technically should be able to kill them all with a fair amount of HP left.
If you're really low on health, blue pill. You should be fine though. Move to the camp just below you, use meditate and make sure you are at similar levels of HP as my screenshot. If in doubt, blue pill. Now the goal here is not to kill the Lizard, but to kill the small Lizards and run away out of range. You should be able to kill both, if you're worried, run after killing the first one. After you're finished, you should be low on mana. Blue pill.
Buy a longsword. The golems at the bottom should have respawned by now. Kill them.
Next go kill the ghosts and then the wolves if they are up. Then kill the blue golems two minions. Remember to meditate in between camps if you can afford the mana.
Check you have enough gold to buy Madred's Razors. You -should- have. Blue pill if you do and buy them. Now remember that blue golem who's minions you killed? Good. Go kill the blue golem, make sure your smite is off cooldown. After you get the buff spam meditate every time it's off cooldown. Kill the ghosts after this, then the red lizard. Continue to go from camp to camp, into the enemies jungle too if possible.
By the time your level 9/10 (possibly higher if you're a lower summoner level than 23. Best thing you can do is try this out in practice matches first.) you should be able to kill dragon. Make sure you have both red and blue buffs, have full hp and smite is off cooldown.
Smite. You need it to jungle. It's as simple as that.
Second summoner skill is entirely up to you. Some people like Flash, Ghost. Exhaust and Teleport. All of these are great spells and entirely up to you, the summoner.
