Kog’Maw vs Vayne Counter Pick
Matchup Summary
What the Data Means
Vayne fights from 550 units and Kog’Maw from 500, yet 557 games recorded on patch 16.13.1 return 57.3% for the Mouth of the Abyss. Base durability is the first reason. Her 550 health and 23 armor at level one both sit below his 635 and 24, and 61 attack damage against 60 means she does not out-trade him on raw statistics either.
Silver Bolts is what makes her dangerous regardless, taking a percentage of maximum health on every third consecutive attack, a threat that grows as Kog’Maw builds health. The condition attached to it is proximity. Condemn knocks a target back and stuns it against terrain, and Tumble repositions for a bonus-damage shot, so her entire damage pattern requires standing in front of him.
Bio-Arcane Barrage denies exactly that. The extended reach, paired with on-hit magic damage weighed against her full health bar, moves the exchange to his chosen distance while it lasts, and Caustic Spittle corrodes the armor and magic resistance she is already short of. Final Hour is the reversal, granting invisibility during Tumble along with a reduced cooldown on it, and a Kog’Maw who spent Void Ooze before it activated is usually caught. Difficulty ratings of 8 against 6 reflect how much of this rests on her execution rather than his.
