How to beat Cassiopeia

Common role: Mid

A DoT mage who grounds you so you can't dash away, then poisons you to death.

What makes Cassiopeia dangerous

Cassiopeia stacks poison with Q and a spammable E (empowered against poisoned targets), grounds an area with W so you cannot dash out, and petrifies you with a frontal ultimate if you are facing her. She scales into an unkillable damage machine who chases you down with movement speed.

How to play against Cassiopeia

• 1Turn away from her when she ults — facing her means a full stun, turned away is only a slow.
• 2Don't dash into her W ground zone; you'll be stuck and poisoned.
• 3Punish her extremely weak, mana-hungry early game hard.
• 4She is immobile — dive her or gank; her only defence is the ground zone.

Weaknesses to exploit

• ✓No mobility — highly gankable and easy to dive.
• ✓One of the weakest, most mana-starved early laners.
• ✓Her ult only stuns enemies facing her — turn away.
• ✓Squishy: burst her before her poison ramps.

Abilities & how to counter them

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

• P
  优雅蛇行

  卡西奥佩娅身上的所有移动速度加成效率变得更多。

  Strong: gains move speed instead of buying boots, letting her chase and kite. Weak: no boots means a flat item disadvantage — burst her when caught.

• Q
  瘟毒爆炸

  在短暂的延迟后，卡西奥佩娅用毒素引爆一片区域，并且如果命中了一名敌方英雄，就会获得移动速度加成。

  Strong: applies poison and grants her move speed — her main poke. Weak: a delayed AoE circle — sidestep it to deny the poison and speed.

• W
  剧毒迷雾

  卡西奥佩娅释放出若干团毒云，对经过毒云的敌人造成减速效果、缚地效果和轻量伤害。被缚地的敌人无法使用位移技能。

  Strong: a ground zone that stops all dashes so you can't escape her. Weak: fixed area — don't dash into it, and walk around the edge.

• E
  双生毒牙

  卡西奥佩娅释放一次攻击，可对中毒的目标造成额外伤害并且基于实际伤害值为她提供治疗效果。如果目标死于这次攻击，卡西奥佩娅会回复法力值。

  Strong: a spammable nuke that refunds mana and shreds against poisoned targets. Weak: it needs poison on you first — cleanse the poison or don't get hit by Q.

• R
  石化凝视

  卡西奥佩娅从眼中放出一团魔法能量，对她前方的任何面对她的敌人造成晕眩效果并对其它背对她的敌人造成减速效果。

  Strong: petrifies everyone facing her for a full stun. Weak: turn away and it's only a slow — face-check her ult and turn your back.

Itemization

Magic resist and grievous wounds (she sustains off Q). Dive her immobile frame early; turn away from her ult to dodge the stun.
