Xayah vs Kog’Maw Counter Pick
Matchup Summary
What the Data Means
On the champion screen, Xayah’s attack reaches 525 units while Kog’Maw’s reaches 500, but Bio-Arcane Barrage extends Kog’Maw’s attack range and turns each hit into magic damage scaled to the target’s maximum health. Once that ability is active, the spacing flips, and the recorded results flip with it: Xayah wins 42.9% over 333 games on patch 16.13.1.
Percent-health damage changes what toughness means here. At level 18, Xayah has 2,449 health, the bigger pool of the two, and since the damage is magic, her 96.4 armor does nothing against it. Caustic Spittle strips armor and magic resist while boosting his attack speed, and Void Ooze lays down a slowing trail that makes backing off costly. Neither champion has a speed edge, as both move at 330. Kog’Maw is the more fragile body beneath all of this, with 635 base health (2,318 at level 18) and 24 base armor against Xayah’s 25, so the burst window is real if he can get into position.
Xayah’s opening comes early, before the range advantage swings. Double Daggers leave behind Feathers, Clean Cuts stacks more after each ability, and Bladecaller turns the entire area into damage plus a root. Hold Featherstorm‘s untargetable leap for Living Artillery, which gets a major boost against low-health foes, and for Icathian Surprise, the true-damage blast that goes off four seconds after Kog’Maw dies. The difficulty ratings are 5 for Xayah and 6 for Kog’Maw. Full kit: Kog’Maw.
