Your W ruins her resets and your R interrupts Death Lotus — stand on your miasma and she literally cannot play the game.
Track: Katarina's E — Shunpo (12–8s cooldown). Her blink to daggers and targets — hard CC during her resets and she folds.
Read from Cassiopeia's seat: which stage windows this plan plays for against Katarina.
This is Cassiopeia's own plan; across 2,353 pooled games the lane is even.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Cassiopeia | Level 1 favors Cassiopeia because Katarina has no ranged tool and must approach through poison-poke range to do anything. |
| Level 2 | Cassiopeia | Level 2 stays in Cassiopeia's favor as Katarina's dagger-based combo is easily punished before she has reset fodder nearby. |
| Level 3 | Cassiopeia | Level 3 continues to favor Cassiopeia since dagger placement near her is instantly punishable with Miasma and Q poison. |
| Levels 4-5 | Even / skill | Levels 4-5 remain lopsided because Katarina still lacks a safe way to engage without eating full poison stacks first. |
| Level 6 | Cassiopeia | Level 6 favors Cassiopeia as Katarina's ultimate roots her in an animation that a fresh Miasma or poison stack can punish severely. |
| First item | Even / skill | Cassiopeia's first item poison ramp threatens to out-damage even her ultimate's burst if she mistimes the channel. |
| Two+ items | Even / skill | Two items in, Cassiopeia's stun-burst combo can delete Katarina outright before her reset-chain engine ever gets started. |
Katarina wants to land an early kill to snowball her E dagger-reset chain, but she has no way to do that safely into your ranged poison poke. Keep chunking her with Q from max range and never let her stack daggers around you unpunished — every dagger she throws near you is a Miasma trap waiting to happen. Because she has no natural escape besides E resets, a well-timed poison stack forces her out of all-in range entirely. Play patient: she has to make the first mistake since she can't out-poke you.
