How to play as Lux
Hold Light Binding(Q) for Caitlyn's committed last-hit or a predictable path instead of throwing it on low odds; after a miss, stay back until the cooldown gives you another opening.
Caitlyn has 100 more basic attack range than Lux (650 to 550), while Lux's Light Binding(Q) and Lucent Singularity(E) reach much farther than her basic attacks.
Light Binding(Q) can bind two enemy units, so a single minion does not always absorb the spell before it reaches Caitlyn.
How to play as Caitlyn
Keep changing direction as you last-hit. If Lux misses Light Binding(Q), use the cooldown window for a short trade or wave pressure, then respect its return.
