Marksman
Beginner Rule
Respect Kog'Maw when Bio-Arcane Barrage (W) is active — that's when his damage spikes.
Kog'Maw is a hyper-scaling marksman who deals enormous sustained damage from range. He wants to activate Bio-Arcane Barrage (W) to shred enemies before they can reach him. Many beginners underestimate how quickly Kog'Maw can melt tanks and frontliners.
First Item – Damage becomes more consistent.
Two Items – Major DPS increase.
Three Items – One of the strongest late-game carries.

QWhat it does
Launches a corrosive projectile reducing Armor and MR briefly, and granting him Attack Speed.
How to play against
After he hits Q you take bonus damage from his attacks. Disengage immediately when debuffed — he chains with W.
WWhat it does
His attacks gain extended range and deal percent max health magic damage on-hit.
How to play against
His W is why building health alone doesn't counter him. Percent-health true damage ignores both armor and health stacking. Kite him away.
EWhat it does
Launches a slow-moving ooze that damages and leaves a slowing trail.
How to play against
Don't chase him through the ooze trail — walk around it.
RWhat it does
Fires a long-range artillery shell dealing magic damage. Stacks of R in quick succession cost more mana.
How to play against
He can barrage from off-screen with R. Stay mobile and behind terrain. His R reveals non-stealthed targets.
W → Auto Attacks
Core damage pattern.
E → W → Chase
Keeps enemies in range.
R Spam → Cleanup
Finishes low-health targets.
Icathian Surprise: on death he becomes a moving bomb that explodes dealing massive true damage. When he dies, back away immediately — he's going to explode.
