IntroductionThis guide will cover how to completely rape faces with Master Yi is 3v3s. Master Yi is a hardcore AD carry. He's squishy, but if played properly can easily become the strongest champion in the game later on. In 5v5s it's recommended that you jungle with Master Yi as he isn't a very strong lane champion, but in 3s jungling is just stupid since there's no blue buff and you're so open to get ganked. So as a result, this guide will be for LANING with Master Yi.
Passive: Double Strike
Master Yi strikes twice every 7th attack.
Q: Alpha Strike
Master Yi leaps across the battlefield striking up to 4 enemies, dealing 100 / 150 / 200 / 250 / 300 (+100% of ability power) magic damage to each enemy with a 20 / 30 / 40 / 50 / 60% chance to deal 400 bonus magic damage to minions.
Cost 80 / 90 / 100 / 110 / 120mana
Master Yi channels, restoring 140 / 280 / 420 / 560 / 700 (+165% of ability power) health over 5 seconds. While channeling, Master Yi gains 100 / 150 / 200 / 250 / 300 armor and magic resistance.
Cost 70 / 85 / 100 / 115 / 130mana
E: Wuju Style
Passive: Increases physical damage by 15 / 20 / 25 / 30 / 35.
Active: Master Yi can activate this ability to double its effectiveness for 10 seconds, but this removes the passive bonus until Wuju Style becomes available again.
Increases Master Yi's movement speed by 40% and Attack Speed by 40 / 60 / 80%, and he becomes immune to all slowing effects for 6 / 9 / 12 seconds. Additionally, killing a champion refreshes all of Master Yi's cooldowns. (Assists reduce half of the base cooldown amount.)
MasteriesI prefer to go 21/9/0 because it gives you a shit ton of damage and makes you a little tankier. The only other possible alternative would be 21/0/9, in which case you would get some health/mana regen, extra experience, and a little extra gold. However, I just don't think it's worth it. Master Yi is really squishy, so you really need the extra magic resist and armor from the defense tree, and then the health regen for laning early game is just icing on the cake.
RunesFor runes, I like to get attack speed marks, armor seals, magic resist glyphs, and health quints. As I've said before, MASTER YI IS SQUISHY!!! You need the armor/magic resist/health runes, no exceptions. For marks, you can use armor pen if you'd like, but I think attack speed is definitely better for Yi.
Flash is OP! It's basically a free "get out of fail" card. Accidentally facecheck a bush with three people waiting for you? FLASH! Soloing top when the other lane comes to gank you and your teammates don't call missing and you're too bad to look at the minimap? FLASH! It will save your life; there is absolutely no room for argument. The second spell, however, is a toss up. I prefer exhaust, but you can also get ignite if you want to. They both have their ups and downs, but I think exhaust is better for Yi. It just nets you a lot more kills than ignite does.
Let's say you take ignite and flash. You're laning bot and you notice that top isn't doing so well and could use a gank. You run up through the jungle and try to come around behind the enemy for a kill. Your ally is a safely behind your creeps and the enemy is behind his. He spots you and immediately heads for his tower. You pop your ult, activate your E, throw on ignite, and proceed to autoattack him a couple times, but he makes it back to his turret with a litte less than half health and lives to fight another day. If you had taken exhaust instead of ignite, then you could have slowed him at the start and gotten a few extra hits in, AND your ally would have been able to catch up and use a stun/slow of his own to ensure the kill.
They're both useful, but I just feel that exhaust will be able to get you more kills than ignite will.
Early GameSome heroes really excel at dominating and taking a lead really early on in the game. Master Yi isn't one of them. You'll want to take the bottom lane with an ally as Master Yi is a horrible solo. The most important thing to remember early on is DO NOT DIE! I've seen so many Yis think they're just the shit at this game and tower dive at level 3-4. Don't do it. It's just not worth it. It's better to just let the kill go early on than to risk dying. Other than that, just sit back and try to last hit. If you're up against opponents that can completely zone you out and just absolutely dominate you, then just stay back and at least get the experience until you can set up a gank.
Mid GameMaster Yi's mid game can be summed up in three words: FARM FARM FARM!!! Master Yi is extremely item dependent and if he doesn't farm well in the mid game, he will get crushed later on. Now don't get me wrong, don't just leave your team hanging if there's a fight going on, but you mainly want to just get as much gold as possible. Spam your Q on creep waves and last hit anything that doesn't get instakilled from it. When a creep wave dies, run up to the jungle and kill some creeps, then come back for the next wave (assuming you have the jungle warded so you don't walk into the enemy team). Just farm as much as humanly possible, and don't die!
Late GameThis is where Master Yi excels. As I said before, Master Yi has one of the strongest late games out of any champion, providing you didn't feed early on. Late game you want to be mobile, and still farming. Just go back and forth between both lanes and the jungle. You want to kill dragon as soon as it respawns and maintain control of the other buffs as well. Just stay passive and farm until you see an opening. If there's one champion out by themselves overextending a little, go for the kill. If the whole team is trying to push your top lane but they're not quite at your turret yet, you can BD their turret and then blue pill back to base while your allies hold them off. Master Yi is one of the best, if not THE best champions for backdooring. Basically, you just want to play defensive until your opponents make a mistake, and then you go for the throat and punish them!
Team FightsI've said it before and I'll say it again: MASTER YI IS SQUISHY! You are not a tank, you are not invincible, you are not an initiator! In team fights, you want to stay back behind your allies and have your tank run in first. Once the enemy team starts targetting your tank, then you Q onto their squishiest champion, pop your E and R, and go to town! You'll be doing so much damage you should be able to melt one of them in a few seconds. If they switch to you, it really doesn't matter because you'll have so much lifesteal that you'll be able to just stand there and take it.
