Kog'Maw, the Mouth of the Abyss, is a marksman and mage champion of medium difficulty. Across our 393 analysed ranked games, Kog'Maw is mostly played as ADC (79% of its games), and more rarely in Mid (21%), with a 55.3% win rate in that role: tier S among ADC champions (#2 of 36, ranked by win rate).

Averages measured over 309 ADC games played with Kog'Maw, from our ranked Solo/Duo data collection.
Kog'Maw is a max-health damage marksman: Bio-Arcane Barrage increases his range and makes him deal magic damage equal to a percentage of the target's max health. Caustic Spittle corrodes armor and magic resistance, Void Ooze slows, and Living Artillery deals greatly increased damage against low-health enemies. His passive makes him explode 4 seconds after death.
