Kogmaw Bot guide

Kog'Maw adc is built around Bio-Arcane Barrage (W), Caustic Spittle (Q), and Living Artillery (R): hold range with Bio-Arcane Barrage's extended on-hit magic damage, open trades with Caustic Spittle to corrode armor and magic resist while gaining attack speed, and finish low-health targets from range with Living Artillery once it comes online.

The build

Rune page: Lethal Tempo, Triumph, Legend: Bloodline, and Last Stand (Precision), with Conditioning and Overgrowth (Resolve). Summoners: Flash and Barrier. Skill order opens and maxes Bio-Arcane Barrage (W) first, with Caustic Spittle (Q) second and Void Ooze (E) last. Starter: Doran's Bow and two Health Potions, into Berserker's Greaves. Core build: Blade of The Ruined King, Guinsoo's Rageblade, and Runaan's Hurricane, with Terminus, Navori Flickerblade, and Wit's End as later options.

Ability mechanics

Caustic Spittle (Q) launches a corrosive projectile that deals magic damage, corrodes the target's armor and magic resist, and grants Kog'Maw bonus attack speed. Bio-Arcane Barrage (W) extends his attack range and adds magic damage equal to a percent of the target's max health on hit. Void Ooze (E) damages everything it passes through and leaves a trail that slows enemies standing on it. Living Artillery (R) fires at long range, hitting harder the lower the target's health and revealing non-stealthed enemies.

Matchups

Hardest matchups by win rate: Jinx, Tristana, Senna, Caitlyn, Ashe. Best matchups: Kai'Sa, Jhin, Ezreal.
