Power spike & playstyle

Weak, immobile early laner who spikes hard at attack-speed items with Bio-Arcane Barrage; a hyper-scaling artillery carry that needs peel.

Bio-Arcane Barrage adds bonus range and percent-max-health magic damage to every auto, which stacks multiplicatively with Blade of the Ruined King's own percent-health hit.

Against tanks and stacked-health teams. This is the highest sustained damage against a frontline available anywhere in the mode.

Against dives. Every point of it requires standing still at 600 range with no escape button of any kind, and Kog'Maw is the slowest carry in the game.

Blade of the Ruined King: active: 15% max HP + MS steal Wit's End: steals 5 MR per hit, 5 stacks Not modelled in this number: Frenzy (10% AS for 2s after a crit — not static).

Living Artillery has no cooldown worth the name and a screen-wide range, so a maxed ultimate behind Liandry's is siege damage that cannot be answered.

In stalled games around objectives, where free chip damage from outside vision range decides who can contest and who cannot.

Once anyone walks at him. Kog'Maw has no escape whatsoever, and the mana cost of Living Artillery stacks until a missed volley empties the bar.

Guide

How to play Kog'Maw in League Classic

Kog'Maw is a siege weapon that five people must escort. In lane, respect your immobility — trade only with support cover. From three items, W melts everything: percent-health magic damage on 700-range autos deletes tanks who thought Warmog's was a plan. Stand behind your entire team, attack whatever's closest safely, and trust peel to matter more than your positioning heroics. Living Artillery zones retreats and finishes runners. If you die less than twice a game, your team probably won; you're that much DPS.
