Prioritize the skill that increases basic attack range and percent Health damage first, then level the one that shreds defenses.
Early on, use the Skill 2 range increase to farm from a safe distance and poke when you see an opening. You have no escape, so keep watching the map for ganks.
Once your core items come together, your damage rises sharply. Trust your team's peel and focus on dealing as much damage as possible during the Skill 2 window. That is where fights are decided.
You become one of the best tank killers among ADCs. Using your Ult from outside their range to secure vision and finish fleeing enemies is strong too. One positioning mistake still means instant death, so treat positioning with great care.
In teamfights, stay at the very back of your formation in the safest spot. Activate Skill 2 and melt whoever approaches, frontline first. As long as you stay alive and keep attacking, the fight tilts heavily your way.
With Skill 2 (Bio-Arcane Barrage) on cooldown, Kog'Maw has short range and little damage. When Skill 2 ends, back off instead of getting greedy, and do not step up for damage until it is ready again.
Gain range and max-HP damage with Skill 2, slow with Skill 3 while auto-attacking, then drop Ult on anyone fleeing.
Slow with Skill 3, poke from long range with Ult, and shred defenses with Skill 1.

A three-step guide set by the official champion library. For difficulty, a higher number means harder to play.
Critical damage is 200% for every champion. These figures exclude items and runes.
Our take
Four more base Attack Damage. From 7.3 Attack Speed is per champion: Kog’Maw carries a 0.665 ratio, 0.2 base bonus Attack Speed, and 0.03 per level.
Our take
The mage item pass let Kog'Maw stack enough AP and mana to shell opponents from complete safety. The higher mana ceiling makes sustained barrages far more expensive, and one step less range forces him to stand closer than before. The artillery identity stays intact, but opponents now have room to close the gap and answer back.
Our take
The max HP scaling on Kog'Maw's empowered attacks loses 0.5% at every rank. Because he stacks attack speed and fires many shots per second, half a percent per hit translates directly into how fast a frontline tank comes down. The larger the enemy health pool, the more they notice the change. Teams that build health now have a little more room to step inside his range and close the gap.
