Kog'Maw has huge reach for an ADC, especially thanks to Bio-Arcane Barrage. He's got great poke, so don't hesitate to try and bully your lane opponents. 

  • Level 1 - Take W - Bio-Arcane Barrage, for the early poke and zoning.
  • Level 2 - Take Q - Caustic Spittle, for more damage and the passive attack speed.
  • First Back - Start working towards Shieldbow, or pick up boots.

Tips & Tricks

  • Caustic Spittle offers vision on impact, so use it to check bushes if you don't have wards up. However, it is an expensive spell, mana-wise. 
  • Always get ready to move during your passive on death, and try to inflict as much damage as possible. 
  • Void Ooze is your only escape tool, so don't always be quick to use it when it's off cooldown.
