Yorick vs Cassiopeia Counter Pick
Matchup Summary
What the Data Means
Cassiopeia carries a difficulty rating of 10, the ceiling of the scale, against 6 for Yorick, and that gap does real work: a champion who has to chain Noxious Blast into Twin Fang without wasting either loses games to her own hands. Patch 16.13.1 records 56.0% for Yorick, though the 100-game sample behind it is the minimum worth reporting and should be held loosely.
The fight is a question of whether she can hold ground. Miasma slows and grounds, denying movement abilities, but Yorick has none to deny — his approach is a walk, and Mourning Mist reduces armor while sending Mist Walkers sprinting toward the marked target. Dark Procession is the sharper tool, since a destructible wall placed behind Cassiopeia removes the retreat her 335 move speed and Serpentine Grace usually guarantee.
Her defences are the thinnest element of the pairing: 18 base armor, 97.9 at level 18, and 2,296 health where Yorick reaches 2,588. Petrifying Gaze stuns only the enemies facing her and slows the rest, a partial answer at best, because the Maiden of the Mist and the ghouls keep attacking through it. Her damage is pure magic against Yorick’s mixed profile, so magic resistance is his first correction and armor is close to wasted gold in this particular lane.
