How to beat Karma as Lux: the early game

Karma controls levels 1-2: her Mantra-empowered Q is a longer, harder root-poke than your Q and its low cooldown lets her bully you off farm before your kit comes online. Her empowered cast is a longer and harder version of yours, so stop contesting and shield the chip instead. Use the zone to hold ground rather than to poke, and save the root for the moment her empowered rotation has already been spent on someone else.
