How to win lane as Kog'Maw against Karthus · 59.09% win rate over 264 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Karthus | Level 1 is Karthus's: Q Lay Waste pokes and contests CS from range you can't answer. |
| Level 2 | Karthus | Level 2 stays Karthus's as Q poke plus E zoning keep you off the wave. |
| Level 3 | Karthus | Level 3 is Karthus's because Defile zones your immobile body off farm. |
| Levels 4-5 | Karthus | Levels 4-5 remain Karthus's on accumulating Q poke and E pressure. |
| Level 6 | Karthus | Level 6 is Karthus's since Requiem threatens to execute you after any trade. |
| First item | Karthus | First item is Karthus's, one AP item makes his Q poke keep you pinned. |
| Two+ items | Kog'Maw | Two-plus items is Kog'Maw's: uncapped W range and %max-HP shred him from outside Defile. |
Karthus controls levels 1-2. His Q Lay Waste lets him contest CS and poke you at range without ever stepping up, and you're the immobile short-range one who can't punish him for it. Last-hit behind minions, respect that repeated Q hits add up fast, and don't walk into E Defile range for a single caster minion. Take safe farm and scale.
