When Is Kog'Maw Strongest?
The mid-game item window is the high point of the curve, and games at this rank average around 29 minutes. Kog'Maw is built to survive to that window, so the plan is to farm safely, avoid getting caught, and let two or three items turn every teamfight into a max-range execution.
Kog'Maw Item Build
Kog'Maw is an immobile hypercarry who melts anything, tank or squishy, once his attacks ramp up. The build stacks attack speed and on-hit damage so his extended-range shots tear through max health, trading his complete lack of escape for absurd late-game output.
Best Kog'Maw Runes
Lethal Tempo plays into his strength as a range-abusing carry, feeding him more of whatever lets him deal damage from safety. However he is built, the plan never changes, which is to shred targets without stepping into danger, and the keystone supports that. Fill the rest of the tree for damage and just enough survivability to hold his ground.

Kog'Maw Skill Order
Kog'Maw takes Void Ooze at level 3 and leaves it there until 14, funneling everything between into Bio-Arcane Barrage and then Caustic Spittle, which buys attack range and resistance shred rather than a stronger slow to kite with.
Kog'Maw Abilities
Between his ramp-up autos sits the setup work of Caustic Spittle, corroding a target's armor and magic resist while handing Kog'Maw a burst of attack speed. Even his corpse bites, since Icathian Surprise detonates for true damage seconds after he dies.
Kog'Maw Base Stats
Kog'Maw Matchups
Kog'Maw has no dash and no self-peel, so anything that dives onto him or locks him down ends the fight before he ramps. Give him a frontline to hide behind and immobile targets to shred, and his range advantage takes over.
