Cassiopeia vs Qiyana Counter Pick
Matchup Summary
What the Data Means
Cassiopeia holds a 550-range poison kit while Qiyana has to close to 150 just to threaten anything, yet the range advantage does not translate into wins: Cassiopeia takes only 43.2% of these 162 games on patch 16.13.1. Terrashape and Audacity both cover ground quickly, letting Qiyana skip through Noxious Blast’s poison zone and Miasma’s grounding cloud before enough Twin Fang procs land to threaten a kill. Royal Privilege adds bonus damage to the first hit of every trade, and once Supreme Display of Talent lands its stun, Petrifying Gaze rarely gets to fire back in return.
At level 18 Qiyana’s 2,545 health and 107.5 armor outscale Cassiopeia’s own 2,296 health and 97.9 armor, so extended trades favor the assassin even after poison ticks add up. Serpentine Grace rewards heavy movement speed investment to keep the gap Qiyana wants to close, and Miasma is the ability that matters most here — landing the ground effect early denies the dash window Terrashape depends on for entry. With a difficulty rating of 10 against Qiyana’s 8, execution mistakes cost Cassiopeia more than they cost her opponent, since a missed Noxious Blast means walking into melee range with no poison stacked at all. Both draw from Mana as their resource, and Qiyana’s 335 move speed matches Cassiopeia’s exactly, so neither side kites away from a landed Terrashape dash for long.
