Who Wins
- Pre-6 you lose this lane — Cassiopeia outranges you significantly, her Q into E poke is consistent, and you have no reliable way to close the gap or trade favorably without your R.
- At level 6 the matchup flips if you land Q, as your R dash into W shield into R reset combo deals massive burst that Cassiopeia's sustained damage cannot answer in a short window.
How to Trade
- Your best trade pattern is to wait for Cassiopeia to overextend or misposition, land Q to mark her, then immediately R in and use W for the shield before she can fully ramp E damage — the goal is to burst her down before her sustained DPS becomes relevant.
- If she dodges your Q, do not engage; without the Q mark your R is a one-way dash into her full damage with no follow-up reset available.
Wave Control
- Let the wave push toward you pre-6 to create a longer walk-up distance for Cassiopeia, which reduces her safe poke angles and sets up a deeper all-in when you hit level 6.
- Post-6 you can look to freeze near your tower to bait Cassiopeia into walking up for CS, giving you the ideal short-range engagement where your burst combo is most lethal.
Mistakes to Avoid
- Do not use R as a pure gap-close without your Q mark active — Cassiopeia's W and E slow will kite you out and you will take full sustained damage with no reset available to escape or follow up.
- Overcommitting to trades pre-6 by walking up repeatedly to auto-attack or use abilities bleeds your HP and makes you an easy kill once Cassiopeia has enough stacks and you lack the HP to survive her level 6 burst window.
