Kog'Maw Build Guide (AD Carry)
Kog'Maw is the ultimate late-game turret: Bio-Arcane Barrage melts tanks by percent of their health, and a protected Kog'Maw simply deletes whatever he looks at. He has no escape - your team's job is to keep the artillery alive.

Kog'Maw Build Guide (Mid)
Artillery Kog'Maw plays mid as a living siege weapon: Living Artillery pokes from beyond vision range, Void Ooze holds the wave line, and nobody sieges into a poke machine that outranges towers.
Summoner Spells


Runes
9x Mark of Magic Penetration (+1 Magic Penetration)
9x Seal of Armor (+1 Armor)
9x Glyph of Ability Power (+1.2 Ability Power)
3x Quintessence of Ability Power (+5 Ability Power)
Magic penetration and ability power turn every Living Artillery into a third of a health bar; armor seals survive the assassins sent to stop it.
Masteries 21/0/9
21/0/9 caster page: the ability power line scales the artillery; utility feeds its enormous mana appetite.
