How to win lane as Locke against Cassiopeia · 54.03% win rate (385 Emerald+ games, lolalytics, sampled July 2026) · Matchup data reviewed on patch 26.15
A poke war you enter at 125 range — pay the toll early, then one blink turns her kite into a coffin the moment the nails land.
Track: Cassiopeia's W — Miasma (24–16s cooldown). Grounds you — dashes and leaps are disabled inside it.
Read from Locke's seat: which stage windows this plan plays for against Cassiopeia.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Level 1 is even but your on-hit trade edges her thin frame. |
| Level 2 | Even / skill | Level 2 stays skill as her E needs a poison setup. |
| Level 3 | Even / skill | Level 3 is a wash around dodging her grounding W. |
| Levels 4-5 | Even / skill | Levels 4-5 remain even as you punish her W cooldown. |
| Level 6 | Even / skill | Level 6 base is even until ults and totems trade. |
| First item | Locke | Locke favoured — a flanking E plus R Purgatory beats her Gaze. |
| Two+ items | Even / skill | Late evens out as her ramping DPS meets your burst. |
Levels 1-2 are even but you have the edge in a fight: Cassiopeia's Q pokes yet her E needs a poison target, so in the 24s her W is down you can E in and out-trade her thin HP with Soul Nails.
