Favour timeline — who owns each window

StageFavouredWhy
Level 1CassiopeiaCassiopeia's Noxious Blast gives her a level-1 range advantage and movement speed to chase — your Q blind is not yet rank 1, so respect her first trade window and last-hit safely.
Level 2Even / skillMiasma and Noxious Blast are both single-target skill shots at level 2 — dodge one and you win the brief skirmish, but if she lands both together she wins the trade, making this a genuine Skill window.
Level 3TeemoQ is rank 2 and your E poison stacks enough to beat her sustained DPS between Noxious Blast casts — blind immediately after she lands her Q and the Twin Fang window disappears entirely.
Levels 4-5TeemoMax-ranked Q erases her entire damage pattern when she throws Noxious Blast: blind the follow-up, stack E poison freely, and mushroom the tribush so she cannot disengage safely.
Level 6TeemoNoxious Trap placements at level 6 seal the river entrances and tribush she relies on for roam angles — she must walk through your shroom field or forfeit map pressure, and her no-boots passive cannot outrun slow stacks.
First itemTeemoLiandry's DoT on top of your E poison and mushrooms means every trade she takes during the Miasma CD deals her 35-40% of her HP in ticking damage; she cannot reset safely enough to contest your lane.
Two+ itemsTeemoShadowflame and Nashor's Tooth turn Twin Fang into a DPS machine she fires every 0.9 seconds inside Miasma — your HP pool cannot outlast her sustained burst in a straight channel fight; never duel her on open terrain at this stage.

Early game (levels 1–5)

Cassiopeia level 1 is dangerous — she hits Noxious Blast at range, stacks poison immediately, and you cannot run without eating Twin Fang follow-ups. Don't auto-trade into her level 1; last-hit at the edge of your AA range and hold Q until she commits a Noxious Blast, then blind her so Twin Fang returns a fraction of its normal DPS. At level 2 the matchup evens: your E poison stacks begin trading blow-for-blow with her sustained damage, and her only kill threat requires Miasma — a ground CC she has to predict. Respect the Miasma pool completely; the moment she drops it on your feet, walk out of the zone before throwing your blind, because Q animation does not interrupt the grounding.
