Belched forth from a rotting Void incursion deep in the wastelands of Icathia, Kog'Maw is an inquisitive yet putrid creature with a caustic, gaping mouth. This particular Void-spawn needs to gnaw and drool on anything within reach to truly understand it. Though not inherently evil, Kog'Maw's beguiling naiveté is dangerous, as it often precedes a feeding frenzy—not for sustenance, but to satisfy its unending curiosity.

Tips

Playing as Kog'Maw

  • Kog'Maw can outrange most champions with his Bio-Arcane Barrage ability.
  • Use Void Ooze to set up a perfect Living Artillery.
  • Make the most out of your Icathian Surprise.

Playing against Kog'Maw

  • Kog'Maw doesn't have a good escape ability, so he is especially prone to ganks.
  • Run away from Kog'Maw after he dies!!!!
  • The range on Living Artillery increases each rank.
  • Bio-Arcane Barrage allows Kog'Maw to kill Baron Nashor extremely early. It can be valuable to ward Nashor when Kog'Maw completes his Blade of the Ruined King.
