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
  虚空之石

  卡萨丁所受的魔法伤害减少，并无视单位的碰撞体积。

• Q
  虚无法球

  卡萨丁向目标发射虚空能量法球，造成伤害并打断目标的技能引导。满溢的能量会在他身边环绕，提供一个可吸收魔法伤害的临时护盾。

• W
  虚空之刃

  被动：卡萨丁的普通攻击会造成额外魔法伤害。主动：卡萨丁的下次普通攻击会造成显著的额外魔法伤害并回复法力值。

  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
  能量脉冲

  附近有单位施放法术技能时，卡萨丁将吸收能量，当充能完毕后，吸收的能量可转化为脉冲，对面前锥形区域内敌人造成伤害并减速。

  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
  虚空行走

  卡萨丁传送到附近区域，对区域内的敌方单位造成伤害。 在一段时间内连续施放虚空行走技能会消耗更多的法力值，但也会造成额外伤害。

  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.
