LeBlanc vs Cassiopeia Counter Pick

Eighteen base armor is the softest opening defense a mid mage can carry, and it rises only to 97.9 by level 18. That single number explains a good part of why LeBlanc records 57.5% over 315 games on patch 16.13.1 with an easy grade attached, even though Cassiopeia is rated 10 for difficulty against her 9.

• No escape tool — Cassiopeia has no dash or blink; Distortion enters and leaves on its own schedule, which makes the all-in far safer than it would be against a mobile mage.
• Grounding — Miasma is the counter, and it removes movement abilities from anyone inside it, so a Distortion return charge spent inside the cloud is simply lost.
• Twin Fang sustain — the heal only applies against poisoned targets, so breaking contact after the burst denies the recovery that keeps her in the exchange.

Both deal magic damage into 30 and 32 magic resist respectively, so the defensive purchases mirror each other and the fight is decided by who lands first. Cassiopeia’s 630 starting health is the larger pool at level one, ahead of the 598 LeBlanc brings, which means the burst has to arrive complete rather than in pieces. Serpentine Grace amplifies every move speed source on Cassiopeia, and Petrifying Gaze stuns anyone facing her, which is the one reversal that beats a committed LeBlanc holding 598 health and 22 armor.
