How to beat Master Yi

Common role: Jungle

A hyper-carry auto-attacker who becomes untargetable and resets his ult on kills.

What makes Master Yi dangerous

Master Yi is untargetable during his Q (Alpha Strike), heals with his W, and his ultimate makes him faster and immune to slows while cutting through a team. If he snowballs, his Q resets on kills let him wipe entire fights. He is farm-dependent and useless if behind.

How to play against Master Yi

• 1Hard CC beats him — but he can dodge single-target CC with his Q. Chain your CC or save it for after his Q, then lock him down.
• 2His ult ignores slows, so bring stuns, roots, and knock-ups instead. A single well-timed stun deletes him in a fight.
• 3Punish him early: invade and pressure his jungle before level 6. A behind Yi never gets the items he needs to carry.
• 4Don't let him reset — never fight a snowballing Yi with your team clumped and low. Peel him off your carries and burst him before he gets a kill.

Weaknesses to exploit

• ✓Completely farm/snowball dependent — weak when behind.
• ✓Melee auto-attacker: hard CC shuts him off.
• ✓No ranged threat and no waveclear pre-items.
• ✓Vulnerable while his Q is on cooldown.

Abilities & how to counter them

What each of Master Yi's abilities does — and how to play around it.

• P
  ダブルストライク

  通常攻撃を数回行うごとに、通常攻撃が2回連続攻撃になる。

• Q
  アルファストライク

  目にもとまらぬ速さで複数の敵を斬り抜け、物理ダメージを与える。この間、マスター・イーは対象指定されない。このスキルの攻撃はクリティカルを発生させる場合もあり、モンスターには追加物理ダメージを与える。通常攻撃をするたびに、このスキルのクールダウンが短縮される。

  Strong: Alpha Strike makes him untargetable, dodging single-target CC. Weak: chain your CC or save it for after Q, then lock him down.

• W
  明鏡止水

  精神を統一して体力を回復する。また効果時間中、受けるダメージを軽減する。さらに、詠唱中は毎秒「ダブルストライク」のスタックを獲得して、「ウージュースタイル」と「ハイランダー」の残り効果時間を一時停止する。

  Strong: heals and reduces damage mid-fight. Weak: Grievous Wounds cuts the heal — anti-heal makes his dives losing trades.

• E
  ウージュースタイル

  通常攻撃が追加確定ダメージを与える。

• R
  ハイランダー

  一時的に移動速度と攻撃速度が増加し、あらゆるスロウ効果を受けなくなる。発動中にチャンピオンに対するキルまたはアシストを達成すると「ハイランダー」の効果時間が延びる。またこのスキルは自動効果を持ち、チャンピオンに対するキルまたはアシストを達成すると、他のスキルのクールダウンが短縮されるようになる。

  Strong: huge attack/move speed and slow immunity to cut through a team. Weak: ignores slows, so bring stuns/roots/knock-ups — one stun deletes him.

Itemization

Yi is AD on-hit: armor and attack-speed slows (Randuin's Omen, Frozen Heart) wreck him, and Grievous Wounds cuts his W healing. Tenacity and hard CC (Exhaust, stuns) are the reliable answers in fights.
