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
  독사의 품격

  카시오페아의 모든 이동 속도 추가 효과가 증가합니다.

  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
  맹독 폭발

  카시오페아가 잠시 후 대상 지역에 독을 폭발시킵니다. 적 챔피언이 독에 맞을 경우 카시오페아의 이동 속도가 증가합니다.

  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
  독기의 늪

  카시오페아가 독구름을 일으킵니다. 독구름을 통과하는 적은 약간의 피해를 입고 이동 속도가 느려지며 늪에 빠져 이동 스킬을 사용할 수 없게 됩니다.

  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
  쌍독니

  카시오페아가 대상에게 강력한 공격을 가하고 그 피해량에 비례해 자신의 체력을 회복합니다. 적이 독에 중독되면 피해량이 상승하며 적이 처치될 경우 카시오페아의 마나가 회복됩니다.

  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
  석화의 응시

  카시오페아가 눈에서 마법의 에너지를 발사하여 정면에서 자신을 바라보는 적을 기절시키고, 등지고 있는 적의 속도를 늦춥니다.

  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.
