Cassiopeia vs Ahri

Confidence mediumUpdated Jun 10, 2026

Overview

Use mid-range trades to apply poison and force extended fights where repeated (E) outdamages Ahri.
Manage spacing tightly to avoid (E) and (R) engages.
Pressure wave to limit Ahri's roam chances after level 6 and deny her pick windows.

Trading pattern

Start trades by landing (Q) or (W) to apply poison, then chain (E) while holding (W) to ground dashes.
Respect (E) cooldown; avoid committing when it's up and punish if she misses it.
Avoid extended trades without poison or when (W) is down to prevent her burst and escape.

Danger windows

Ahri is most dangerous when (E) and (R) are available for pick or escape.
Avoid committing when (W) slow is down, as Ahri can freely dash or (E) you.
Punish Ahri if she uses (Q) on the wave, creating a window before she can trade back safely.

Early game

Punish Ahri's attempts to farm inside your range with (Q) and (W) to apply poison early.
Avoid trading if (Q) poison or (W) slow is missed to prevent her burst with (E).
Push the wave after level 3 to reduce Ahri's roam potential and force her to farm under tower.

Power spikes

Level 6 (R) unlocks strong all-in and pick potential; use it for verified engages or defensive resets.
First mana/AP item boosts sustained damage and mana pool; increase pressure and extended trades.
Respect Ahri's level 6 (R) and first item spikes by playing around cooldowns and holding (W) to ground dashes.

Win conditions

Win extended trades by landing poison with (Q)/(W) and chaining (E) while controlling space with (W) and (R).
Deny (E) punish windows by spacing carefully and punishing missed charms.
Pressure the wave to limit Ahri's roam potential and force unfavorable trades before her level 6 spike.
