Favour timeline — the windows in Mel's game plan

Read from Mel's seat: which stage windows this plan plays for against Cassiopeia.

StageFavouredWhy
Level 1MelCassiopeia level 1 has only one slow Noxious Blast and no poison ramp — your ability plus ranged auto out-poke her clean here.
Level 2Even / skillYour Q plus Solar Snare root is a real punish window, but her Q poison already threatens to power up Twin Fang if you overstay — call it even.
Level 3Even / skillShe gets Twin Fang online and her poison starts ramping; your Rebuttal reflect keeps it a coin-flip, but the poke war is tightening.
Levels 4-5CassiopeiaFrom 4-5 Twin Fang spam on a poisoned target out-DPSes your Q, and Miasma's slow pins you inside its 700 range.
Level 6CassiopeiaPetrifying Gaze's face-stun lets her front-load Twin Fang burst on you, and Golden Eclipse doesn't win that all-in.
First itemEven / skillHer first-item Twin Fang ramp and your first-item poke peak roughly cancel — neither cleanly wins the trade.
Two+ itemsMelYour infinitely-scaling Overwhelm passive keeps you a max-range R execute threat even as she ramps, reclaiming a sliver of the late game.

How to beat Cassiopeia as Mel: the early game

Cassiopeia's level 1 is one of the worst in the game — no poison engine yet, just one slow Noxious Blast — so your one-ability poke and ranged auto actually edge her here. Hit level 2 with Q plus Solar Snare and you have a real punish: root her stepping up to last-hit, then drop Q bolts before her Twin Fang comes online. After 3 it flips fast — once her poison is rolling, every Noxious Blast on you powers up Twin Fang, and she out-DPSes your Q. Don't sit in the poison; bait her Q with Rebuttal up and reflect it.
