Favour timeline — who owns each window

StageFavouredWhy
Level 1FioraYou are a top-tier level-1 duelist and she has no Miasma, little poison and no escape yet — Q in for a Vital and win the first short trade outright.
Level 2Even / skillWith one rank in Q and Bladework (E) you can still threaten a guaranteed-crit Vital, but the instant she ranks Miasma the trade math tips toward even — bait the ground field, do not eat it.
Level 3CassiopeiaNow she has Miasma to ground your Lunge plus Noxious Blast and Twin Fang out-ranging you — she pokes you off the wave and you cannot close, so farm at the tip of Q.
Levels 4-5CassiopeiaShe chains Miasma grounding and Twin Fang poison while her Noxious Blast slow kites your Lunges — trade only when her Miasma is on cooldown.
Level 6CassiopeiaPetrifying Gaze (R) is a frontal face-stun that locks you mid-dash while her poison finishes you — do not Lunge in facing her, hold Riposte to parry it into a stun on her.
First itemCassiopeiaHer Liandry's-plus-Rylai's poison out-DPSes your Vital heals at one item and she still has R to blank your all-in — wait for a flank or a gank, do not duel her straight.
Two+ itemsEven / skillAt two-plus items she out-scales you as a kiting AP carry — your side-lane flank with R and the heal zone can still one-shot an immobile Cassiopeia if you catch her, but on even terms she wins the open fight, so pick your window or let your team peel.

Early game (levels 1–5)

Level 1 is yours — you are one of the best level-1 duelists in the game and she has no Miasma, little poison and no escape yet, so Q in for a Vital and make her flinch off the first wave. The moment she hits 2-3 it flips: Miasma (W) is a ground zone that cancels your Lunge dash, and her Noxious Blast plus Twin Fang poke out-ranges you, so stop walking up raw and last-hit at the tip of Q. Do NOT burn Riposte on a poison tick — it blocks one instance, not her damage-over-time, and you need it saved for her R.
