How to win lane as Cassiopeia against Locke · 45.97% win rate (385 Emerald+ games, lolalytics, sampled July 2026) · Matchup data reviewed on patch 26.15
He's a 125-range mana champ walking into your poke — win the lane at range and never gift the one blink window that flips it.
Track: Locke's Q — Ritual Nails (10–6s cooldown). The nail marks are his whole engine — without 2-3 stacks on you his blink-in barely dents; sidestep the recasts and punish the ten seconds of nothing.
Read from Cassiopeia's seat: which stage windows this plan plays for against Locke.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Level 1 is even — his on-hit trades sting your squishy frame, but your Q poke makes his walk-up expensive; nobody trades for free. |
| Level 2 | Even / skill | Level 2 stays even: your E needs poison up before it pays, so trades stay short and honest on both sides. |
| Level 3 | Even / skill | Level 3 is a wash that revolves around Miasma — ground Ashen Pursuit on his approach and you win the exchange, miss and he closes for free. |
| Levels 4-5 | Even / skill | Levels 4-5 stay even — he hunts your W cooldown windows while you punish every approach with Q-into-E poison grinding. |
| Level 6 | Even / skill | Level 6 opens even: base ults and totems roughly trade, and your Gaze keeps his straightforward engages honest. |
| First item | Locke | First item is Locke's — a flanking E around your Gaze into Purgatory beats you. Ward the flanks, hug walls and never fight at execute-range health. |
| Two+ items | Even / skill | Late settles even as your ramping DPS meets his burst: he kills you through one clean pick, you melt him through one landed Gaze. |
An even but twitchy lane. His on-hit walk-ups sting your thin frame, so make him pay for every approach: Q on his path, then E him while poison ticks. Your E needs that poison setup, so don't spam it raw. From 3 on, drop W where he has to cross — grounding kills the 10-second Ashen Pursuit.
