Mel vs Cassiopeia Counter Pick
Matchup Summary
What the Data Means
Matched reach at 550 units, near-identical health pools and a computed grade of even: the mid matchup between Mel and Cassiopeia reads 49.5% across 184 games on patch 16.13.1, close enough to a coin flip that the pilot outweighs the pick.
Skill is where they separate. Cassiopeia carries a difficulty rating of 10, the top of the scale, built on Twin Fang’s short cooldown against poisoned targets and on Serpentine Grace, which amplifies every move speed bonus she receives. Mel is rated 5 and works from a simpler loop: each ability loads Searing Brilliance projectiles onto her next attack, up to nine at once.
Defensively neither wants to be hit. Mel holds 630 health and 21 armor at level one, Cassiopeia 630 and 18, and by level eighteen it is 2,313 against 2,296 — a gap of seventeen health after seventeen levels. Magic damage on both sides makes armor a wasted purchase here; magic resistance and cooldown discipline settle the exchange. Move speed reads 330 against 335, a difference Serpentine Grace widens whenever Cassiopeia gains any speed bonus at all.
The tactical hinge is Rebuttal against Miasma. Mel’s barrier reflects enemy projectiles and prevents damage outright; Cassiopeia’s clouds ground enemies so movement abilities cannot be used, and Petrifying Gaze stuns anyone still facing her when it lands.
