How to beat Kassadin

Common role: Mid

A late-game monster who blinks around fights and is nearly unkillable at 16.

What makes Kassadin dangerous

Kassadin is weak and passive early but becomes one of the scariest scaling mids in the game. His ultimate is a short-cooldown blink that lets him engage, dodge and reposition endlessly, while his kit shields against magic and silences. Once he hits level 16 he can one-shot squishies and is almost impossible to pin down.

How to play against Kassadin

• 1Punish him HARD before level 6-16 — Kassadin is one of the weakest early laners. Push, roam, take plates and end the game before he scales.
• 2Deny his farm and level lead. His power is entirely tied to hitting his level spikes; slow his XP and you delay his takeover.
• 3In the late game he'll blink onto your carry — bring hard CC and peel. His only defense is mobility, so lock him down the moment he engages.
• 4Close the game as a team before ~35 minutes. The longer it goes, the more unbeatable Kassadin becomes.

Weaknesses to exploit

• ✓Extremely weak early game — abuse the first 15 minutes.
• ✓Scaling-dependent; a fast game denies his spikes.
• ✓Squishy and killable if you lock his mobility with CC.
• ✓Falls behind if denied farm and XP.

Abilities & how to counter them

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

• P
  ヴォイドストーン

  受ける魔法ダメージが減少し、ユニットをすり抜けられるようになる。

• Q
  ヴォイドスフィア

  指定した対象にヴォイドエネルギーの球体を発射してダメージを与え、詠唱を妨害する。さらに余ったエネルギーがカサディンを包み込み、短時間魔法ダメージを防ぐシールドを発生させる。

• W
  ネザーブレード

  自動効果: 通常攻撃に追加魔法ダメージが付与される。発動効果: 次の通常攻撃に強烈な追加魔法ダメージが付与され、敵に命中するとマナが回復する。

  Strong: empowers his damage and shields against magic. Weak: he's melee — poke with physical or all-in before he has energy for it.

• E
  ヴォイドパルス

  自身の付近でスキルが使用されると、そのエネルギーを「ヴォイドパルス」にスタックする。スタックが溜まると同時に「ヴォイドパルス」が発動可能になり、使用すると扇状の範囲内の敵にダメージを与え、スロウ効果を付与する。

  Strong: a cone that slows and silences, stopping your escape and casts. Weak: it's a skillshot — sidestep it and he can't lock you for his combo.

• R
  リフトウォーク

  近くの地点に瞬間移動し、付近の敵ユニットにダメージを与える。連続して使うとマナコストが増加するが、同時に与えるダメージも増えていく。

  Strong: a short-cooldown blink — endless engage, dodge and escape, near-unkillable late. Weak: costs escalating mana; bait blinks to drain him, and CC him the instant he arrives.

Itemization

Kassadin is AP (with magic-damage scaling). Early magic resist blunts his poke, but the real answer is tempo: end before he scales. Late game, hard CC and a Zhonya's/Banshee's on your carry survive his blink burst.
