How to beat Mel as Cassiopeia: the early game

Mel's ranged poke tools chip you down in the first couple levels and a landed Solar Snare into Radiant Volley hurts, since your own kit doesn't have the range to punish her yet. Her shield ability is built to blunt burst damage, though, which means your Q-E poison ticks bypass a chunk of its value even this early. Play patiently, dodge her skillshot, and look for trades once her poke is on cooldown.
