Gameplay

How to Play Kog'Maw

Kog'Maw is the highest DPS ADC in the late game. His W gives range and %max HP magic damage, making him the ultimate tank shredder. He needs a team to protect him — zero mobility, zero escape.

01
Early Game
Farm Safely, Survive
  • Farm safely. You're the weakest ADC early. Don't trade.
  • W gives extra range for 8 seconds. Use it to poke when it's active, then back off.
  • E slow is your only self-peel. Place it between you and threats.
  • You have NO escape. Position extremely carefully.
  • Let your support dictate trades. Follow up with W autos.
02
Mid Game
W Active DPS
  • W + on-hit items = devastating DPS. Activate W before every fight.
  • Q shreds armor + MR. Hit tanks before auto-attacking for amplified damage.
  • R artillery poke from long range. Don't spam it — mana cost stacks.
  • Stay behind your entire team. One assassin reaching you = death.
  • You need your team to protect you. Communicate this.
03
Late Game
Highest DPS in the Game
  • You deal the most DPS of ANY champion at full build. 6% max HP per auto with W.
  • Guinsoo's doubles your on-hit procs. W + BotRK + Kraken + Guinsoo's = tanks die in 3 seconds.
  • Position behind everyone. You are the win condition — if you die, your team loses.
  • W range at max rank rivals Caitlyn's. You outrange most champions.
  • If protected, you're literally unkillable. Lulu + Kog'Maw is the most broken combo in the game.

Team Comp

Best Synergies

Lulu
Shield/Heal
Lulu
The best protect-the-carry pairing — Lulu R knockup, W polymorph, E shield, and Ardent attack speed buff all directly keep Kog'Maw alive and attacking at full W DPS throughout teamfights.
Janna
Peel
Janna
R Monsoon physically pushes all assassins and divers off immobile Kog'Maw; Tailwind movement speed prevents him from being caught while W active gives his extended range poke.
Malphite
Frontline
Malphite
Malphite's hard engage and tankiness absorb all incoming damage so Kog'Maw can freely auto-attack with W active — Malphite's R groups enemies for Kog'Maw's W on-hit AoE.
Karma
Shield/Heal
Karma
Mantra E speed plus E shield protect Kog'Maw; Ardent Censer attack speed buff stacks with his W DPS steroid for an even larger on-hit damage output during the shield window.
