[14.9] Kog'Maw, the Mouth of the Abyss [Full Guide]

By Foxirion
Introduction
    Greetings Summoners, I am Foxirion, your guide to mastering Kog'Maw in the ADC and Mid lanes. Join me as we unravel the mysteries of the Void puppy and unleash his devastating power on the Rift.
    Kog'Maw's long-range artillery and unique bio-arcane abilities make him a deadly force in both the ADC and Mid roles. Whether you're looking to shred through enemy tanks as an ADC or poke down opponents from afar in the mid lane, Kog'Maw's damage potential and scaling will leave your enemies trembling.
    In this guide, I will share valuable insights on Kog'Maw's playstyle, itemization choices, positioning tips, and strategies tailored to both the ADC and Mid positions. From melting through frontlines in teamfights to sieging towers with your long-range bio-arcane barrage, you'll learn how to maximize Kog'Maw's potential and carry your team to victory.
    Embark on this journey with me as we embrace the power of the Void with Kog'Maw by our side. Together, we will rain destruction on our foes, secure objectives with precision, and dominate the Rift as the Void puppy asserts his dominance in the ADC and Mid lanes.
Abilities

Passive - Icathian Surprise

Upon dying, Kog'Maw detonates, dealing true damage to nearby enemies. After a short delay, he respawns at his fountain. This passive can sometimes turn the tide of a fight, especially if positioned strategically near enemy champions.

Q - Caustic Spittle

Kog'Maw launches a corrosive projectile, dealing magic damage and reducing the target's armor and magic resist. This ability is great for shredding through tanky opponents and increasing Kog'Maw's overall damage output.

W - Bio-Arcane Barrage

Kog'Maw's attacks gain range and deal a percentage of the target's maximum health as bonus magic damage. Activating this ability increases Kog'Maw's attack speed for a duration. Bio-Arcane Barrage is a key ability for Kog'Maw's scaling and melting down tanky champions.

E - Void Ooze

Kog'Maw lobs a ball of ooze that explodes upon landing, dealing magic damage to enemies hit and leaving a trail that slows enemies who walk over it. Void Ooze is a versatile ability that can be used for both offense and defense, as it provides crowd control and zoning potential.

R - Living Artillery

Kog'Maw launches a living artillery shell at a target location, dealing magic damage to enemies hit. This ability can be cast multiple times within a short time frame, but each subsequent cast within a few seconds costs additional mana. Living Artillery is Kog'Maw's long-range poke and finishing tool, allowing him to apply pressure across the map.

Barrier

Barrier provides Kog'Maw with a temporary shield that absorbs damage, enhancing his survivability in skirmishes and duels. It can be used to block burst damage or mitigate incoming damage during crucial moments. Barrier can help Kog'Maw survive all-ins, assassinations, or unexpected bursts of damage from enemies.
