Early game (levels 1–5)

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.
