A geometry war at equal range — E the contact point, hold Q for her step-up, and let the passive autos tip the ledger.
Track: Cassiopeia's W — Miasma (24–16s cooldown). Grounds you — dashes and leaps are disabled inside it.
Read from Lux's seat: which stage windows this plan plays for against Cassiopeia.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | At level 1 Lux dramatically out-ranges a short-ranged, unstacked Cassiopeia and pokes freely. |
| Level 2 | Even / skill | Through level 2 Lux keeps the range and poke advantage before Cass has mana or stacks. |
| Level 3 | Even / skill | By level 3 Cass's Twin Fang and Miasma come online, evening the spacing-and-mana exchange. |
| Levels 4-5 | Cassiopeia | At level 4-5 Cass's ramping DoT and slow start out-trading Lux in sustained fights. |
| Level 6 | Cassiopeia | Level 6 gives Cass Petrifying Gaze, a hard counter to Lux's stationary combo, favoring Cass. |
| First item | Cassiopeia | On her first item Cass's sustained damage and slow chain clearly out-DPS Lux. |
| Two+ items | Cassiopeia | Late game Cass's grounding, DoT, and AoE stun out-scale Lux's single-target pick potential. |
Lux has a clear range advantage in the first two levels: Cassiopeia is short-ranged, immobile, and mana-starved before she stacks her passives, so Lux can poke her freely with Q and E. Zone Cass off farm and deny her Q stacks to keep her behind. This is Lux's best window in the matchup, so press the tempo hard. Track Miasma (W): 24s at rank 1, 16s at rank 5 — it grounds, so it is her window, not yours.
